A social media bio is the shortest piece of writing you will publish as an author, and one of the most read. People see it before they see a single post. On Instagram, TikTok or X, you have a line or two to tell a stranger what you write and why they should follow you.

This guide gives you short author bio examples for each platform, a simple formula, and a list of things to leave out. If you want a quick starting point, the free Author Bio Generator creates a social-length bio alongside short, medium and long versions.

What a short author bio needs to do

A short bio has one job: help the right reader decide to follow you or click through to your book. To do that in a sentence or two, it should cover:

• What you write. Genre or topic, in words readers actually search for.
• A hook. Something specific: your tone, your setting, your background, your promise to the reader.
• A next step. Your latest book, a series name, or “link below” if the platform has a link field.

Each platform sets its own character limit for bios, and these change from time to time. Write to fit comfortably on a phone screen and let the app’s counter tell you if you need to trim.

A formula you can reuse

[What you write] + [specific hook] + [where to start]

For example: “Cozy mysteries with small towns and big secrets. Book 1 of the Lighthouse series out now.” That is two short sentences, and a reader knows exactly what to expect.

Short author bio examples for Instagram

Instagram is visual, and readers there often browse by genre hashtags. Your bio sits right under your name, so it works best when it reads like a tagline. Line breaks and a small number of emoji are common, but they are optional.

• Romance author. Slow burns, small towns, happy endings guaranteed. New book below.
• Writing dark fantasy with morally gray heroes. Book 2 of The Salt Crown out in spring.
• Thriller writer and former ER nurse. Medical suspense that keeps you up at night.
• Poet. Short poems about long days. Second collection out now.
• Helping first-time gardeners grow food in small spaces. Author of The Balcony Harvest.

Short author bio examples for TikTok

TikTok bios are very short, and many readers decide based on your videos rather than your bio. Use the bio to confirm what they just watched and point them to your book.

• Fantasy author. Enemies to lovers, dragons optional.
• I write the cozy mysteries I wanted to read. Book 1 below.
• Debut thriller author. Ask me about the twist.
• Historical fiction about women history forgot.
• Indie author sharing the whole publishing journey.

Short author bio examples for X

X bios are read by other writers, readers, journalists and podcast hosts. A slightly more professional tone works well here, and it is fine to include your day job if it adds credibility.

• Author of the Lighthouse Mysteries. Former harbor master. Writing book 4.
• Science fiction writer. Software engineer by day. Debut novel out with a small press this fall.
• Writing practical guides for new freelancers. Author of Rate Card. Talks about money so you don’t have to guess.
• Middle-grade author and school librarian. Books about brave, curious kids.
• Memoirist. Writing about grief, humor and the strange things families keep.

Short author bio examples for LinkedIn and Threads

LinkedIn headlines and Threads bios are worth a mention too. On LinkedIn, your headline often matters more than your summary, because it appears next to your name everywhere you comment. It is a good place to combine your profession and your book, especially for nonfiction authors.

• HR consultant and author of Hire Slow, a practical guide to building small teams.
• Registered dietitian. Author of The Sunday Prep Plan. Helping families eat well on busy weeknights.
• Novelist writing literary fiction about work, family and second chances.

Threads is linked to your Instagram account, so many authors keep the two bios consistent and only adjust the wording slightly.

Short bios for first-time authors

If your first book is not out yet, you can still write a strong short bio. Focus on what you write and what is coming, without overpromising dates you are not sure of.

• Debut author writing atmospheric thrillers. First novel coming soon.
• Writing my first romance novel and sharing the process.
• Aspiring cookbook author. Recipes from my grandmother’s kitchen, written down at last.

For longer debut bios, see our debut author bio examples.

First person or third person on social?

On social media, first person usually feels more natural because people expect to hear from you directly. Third person can work on X or LinkedIn if you want a more formal, press-style tone. Whichever you choose, keep it consistent across your profiles so you sound like the same person everywhere. Our guide to third person author bio examples covers when each style works best.

What to leave out

• “Aspiring writer” when you have published. If your book is out, you are an author. Say so.
• Vague lines like “lover of words.” Almost every author bio says this. Replace it with your genre.
• Too many hashtags. One or two relevant tags at most, if any. The bio should read like a sentence.
• Every platform and book you have. Point to one next step. A link page can hold the rest.
• Claims you cannot back up. “Bestselling” should mean something specific and true.

Turning a long bio into a short one

If you already have a full author bio, you can cut it down in three steps:

1. Underline the phrase that says what you write.
2. Underline the single most interesting fact about you.
3. Combine them in one sentence, then add your book or series name.

Example: from a 150-word bio about a former teacher who writes historical mysteries set in 1920s Chicago, you get: “Historical mysteries set in 1920s Chicago, by a former history teacher. Book 1 out now.”

If you do not have a full bio yet, start with our guide on how to write an author bio, then shorten it.

Frequently asked questions

How long should a short author bio be?

One or two sentences is enough for social media. Each platform has its own character limit, so write a version that fits comfortably on a phone and check the app’s counter before saving.

Should my short bio include my book title?

Yes, if you have one book or a series to point to. Readers who like your bio need to know where to start, and a title or series name gives them that next step.

Can I use the same bio on every platform?

You can use the same core message, but small adjustments help. Instagram and TikTok suit a casual tone, while X and LinkedIn often suit a slightly more professional one.

Is it okay to use emoji in an author bio?

A few can work on Instagram and TikTok if they fit your genre’s tone. Keep the bio readable without them, and avoid replacing key words with symbols.

Keep every version in one place

Most authors end up with several bios: one for each social platform, one for Amazon, one for the back cover, and short and long versions for press. When a podcast host or blogger asks for your bio, you want to send the right one immediately. Our Author Media Kit Template has a page for your bios, headshot and book details so they are always ready to share.

When you set up a paperback on Kindle Direct Publishing (KDP), one of the first choices is the interior paper. For a book with a black-and-white interior, the main decision is cream or white. It looks like a small detail, but it affects how your book feels to read, how thick the spine is, and whether your cover file fits.

This guide explains the real differences between cream and white paper on KDP, which genres usually use each, and what changes when you switch. If you already know your page count, you can see the exact effect on your spine with our free KDP Spine Width and Cover Size Calculator.

What KDP offers

According to KDP’s help page on print options, paperbacks with black ink can be printed on cream, white or groundwood paper. Cream and white are listed at 50 to 61 pound (74 to 90 GSM). Groundwood is a lighter 45 pound (60 GSM) paper, and KDP says groundwood printing costs about 5% less per page than cream or white.

Color books work differently. Standard color paperbacks use white paper at 50 to 61 pound, and premium color uses heavier white paper at 60 to 71 pound (88 to 105 GSM). KDP notes that white paper shows a higher contrast for images and graphics. In other words, cream is only a choice for black-and-white interiors.

KDP also notes that paper weight can vary based on the printing location, so treat these as ranges rather than exact specifications.

Cream vs white at a glance

	Cream	White
Available with	Black ink only	Black ink, standard color, premium color
Spine thickness per page (KDP)	0.0025 in	0.002252 in
Typical use	Novels, memoir, narrative nonfiction	Nonfiction with charts, workbooks, images, color books
Feel	Warmer, softer contrast, traditional “novel” look	Crisper contrast, brighter page

How the paper changes your spine

This is the part that catches people out. KDP’s cover guidelines use a per-page multiplier to calculate spine width: 0.0025 inches per page for cream and 0.002252 inches per page for white (black-and-white interiors). Cream is slightly thicker, so the same page count gives a wider spine.

• 200 pages: cream 0.500 in, white 0.450 in
• 300 pages: cream 0.750 in, white 0.676 in
• 400 pages: cream 1.000 in, white 0.901 in

The difference grows with page count. At 400 pages it is about a tenth of an inch, which is more than enough to push spine text off-center or make a cover file fail review. Your full cover width is the back cover, the spine and the front cover plus 0.125 inches of bleed on each outside edge, so a change in spine width changes the whole cover size.

The practical rule: choose your paper before you design your cover, and if you ever change it, rebuild the cover at the new size. The spine calculator gives you the spine width and full cover dimensions for both papers, plus a 300 DPI template you can design over.

Which genres use cream?

Cream is the traditional choice for books people read in long stretches. Most fiction from traditional publishers is printed on off-white paper, so readers associate it with novels. Cream is commonly chosen for:

• Novels in every genre: romance, mystery, thriller, fantasy, literary fiction
• Memoir and personal essays
• Narrative nonfiction, history and biography with few images
• Poetry collections

Many readers find cream easier on the eyes over a long session because the contrast between text and page is a little softer.

Which genres use white?

White is the better fit when the interior includes anything visual or anything the reader needs to see sharply:

• How-to and practical nonfiction with diagrams, tables or screenshots
• Workbooks, journals and planners
• Cookbooks with black-and-white photos
• Textbooks and study guides
• Any book with a color interior, since color requires white paper on KDP

Photos and gray-scale images can look muddy on cream because the warm base color shifts the tones. If your book has more than a handful of images, white is usually the safer choice.

What about groundwood?

Groundwood is a lighter, lower-cost paper available for black-ink paperbacks. KDP says it costs about 5% less per page to print, which can help on long books where printing cost eats into royalties. It is thinner and more like the paper used in mass-market paperbacks. If you consider it, order a proof copy first and decide whether the feel suits your book and your readers. KDP’s spine multipliers for groundwood should be checked on its cover guidelines page before you design.

Can you switch later?

KDP’s help page says that after publication, black-and-white paperbacks can switch between cream and white, cream and groundwood, or white and groundwood. Color-ink titles cannot switch paper type. If you do switch, remember that your spine width changes, so upload a new cover at the correct size.

How to decide in five minutes

1. Does your interior use color? Then the choice is made: white.
2. Does it rely on photos, charts or diagrams? Choose white for contrast.
3. Is it mostly continuous text that people read for hours? Choose cream.
4. Look at the top books in your category. If most competitors use cream, readers in that genre expect it.
5. Order a proof. Holding the printed book answers the question faster than any guide.

Checklist before you upload

• Paper type chosen and noted with your final page count.
• Spine width calculated for that paper and page count.
• Cover built to the matching full size with 0.125 in bleed.
• Spine text only if your book has at least 79 pages, which is KDP’s minimum for spine text.
• Trim size confirmed. If you are still deciding, read KDP trim sizes explained.
• Cover dimensions double-checked against our KDP paperback cover size guide.

Frequently asked questions

Is cream or white paper better for a novel on KDP?

Cream is the more traditional choice for novels and is what many readers expect in fiction. White works too, but it gives a brighter, higher-contrast page that suits nonfiction and illustrated books better.

Does cream paper cost more than white on KDP?

KDP’s print options page does not list a price difference between cream and white. It does say groundwood costs about 5% less per page than cream or white, and that color printing costs more.

Why did my cover get rejected after I changed paper?

Cream is thicker per page than white, so changing paper changes the spine width and the full cover size. Recalculate the spine and upload a cover built to the new dimensions.

Can I use cream paper for a color book?

No. On KDP, standard color and premium color interiors are printed on white paper only.

Getting ready for launch

Paper and cover are only part of launch preparation. Once your book is printed, you will start getting requests from bloggers, podcast hosts and local media for your bio, cover image and book details. Our Author Media Kit Template puts all of that in one editable file so you can reply in minutes.

Not sure what page count to expect? Estimate it from your manuscript with the Word Count to Page Count Calculator, then check your final spine and cover size for cream and white with the KDP Spine Width Calculator.

Your Amazon author page is one of the few places a reader goes specifically to learn about you. They have just finished your book, or they are deciding whether to try it, and they click your name. What they find there is your Author Central bio. For many self-published authors it is either empty, copied from a back cover, or written years ago for a different book.

This guide covers how to write an Amazon Author Central bio that does its job: what to include, how long it should be, how it differs from the bio on your book, and examples you can adapt. If you want a fast first draft to edit, our free Author Bio Generator produces short, medium and long versions in first or third person.

What your Author Central bio is for

Author Central is Amazon’s free service for authors. Once you claim your books there, you can manage your author profile, which shows your name, photo and biography on your Amazon author page. The bio can also appear near your books on Amazon.

The reader looking at that page usually wants three things answered quickly:

• Who are you? One or two facts that make you real: where you live, what you do, why you write.
• What do you write? Genre, series, or the kind of nonfiction problem you help with.
• Should I read more of your books? A reason to trust you, and a pointer to what to read next.

Everything in the bio should serve one of those three questions. Anything that does not, such as a long list of every job you have had, can usually go.

Amazon’s guidelines: what to keep in mind

Amazon publishes its own content rules for author profiles inside Author Central, and they can change, so treat the editor in your account as the final word. A few principles are consistent with how Amazon treats customer-facing content in general:

• Keep it about you as an author. The bio is not the place for advertising, discount codes or calls to buy from other stores.
• Avoid contact details and outside links in the text. Readers who want more will search for your name. Your website belongs on your own channels.
• No reviews or ratings. Quoting your own star ratings or reader reviews in the bio is a bad fit for the page and can get the text rejected.
• Accurate and current. If your bio mentions a “forthcoming” book that came out two years ago, readers notice.

Before you paste anything in, check the length allowed in the biography field of your own Author Central account. The field shows you when you have gone over, and a bio that fits comfortably is easier to read than one pushed to the limit anyway.

How long should it be?

Most strong Author Central bios run between 100 and 250 words. That is long enough to show some personality and context, and short enough that a reader on a phone will finish it. A useful test: if a sentence does not tell the reader something they would want to know before buying your next book, cut it.

If you write in more than one genre under the same name, you may need a little more room to explain that clearly. If you write under a pen name, keep the bio consistent with that identity.

First person or third person?

Both are used on Amazon. Third person (“Maya Ortiz writes…”) reads like a book jacket and feels more formal. First person (“I write…”) feels direct and personal. Many indie authors find first person suits Author Central because the reader has already chosen to visit your page, so a more personal tone fits. Pick one and stay consistent within the bio. If you are unsure, our guide on how to write an author bio walks through the trade-offs.

A simple structure that works

1. Opening line: who you are and what you write. “Maya Ortiz writes cozy mysteries set in small coastal towns.”
2. Credibility or connection. Something that explains why you write this: a profession, a place, an experience. “Before turning to fiction, she spent fifteen years as a harbor master.”
3. Your books. The series name, the number of books, or the book a new reader should start with. “Her Lighthouse Mysteries series begins with The Keeper’s Secret.”
4. A human detail. One line about life outside writing. “She lives in Maine with her husband and a very opinionated cat.”
5. A soft next step. “New readers can start with book one, which stands alone.” Keep it inside Amazon: you are pointing to your books, not to another store.

Amazon Author Central bio examples

These examples are written for invented authors. Use them as patterns, not text to copy.

Cozy mystery, third person (about 90 words)

Maya Ortiz writes cozy mysteries set in small coastal towns where everyone knows everyone, and someone always knows too much. Before turning to fiction, she spent fifteen years working on the water, which is where most of her plots begin. Her Lighthouse Mysteries series follows retired lighthouse keeper June Calloway as she solves crimes the local sheriff would rather ignore. The series begins with The Keeper’s Secret. Maya lives on the coast of Maine with her husband and a cat who supervises every chapter.

Nonfiction, first person (about 85 words)

I’m a registered dietitian who spent ten years helping busy parents feed their families without spending every evening in the kitchen. I started writing because the same questions came up in every appointment, and a book could answer them better than a fifteen-minute session. My books focus on simple, budget-friendly meal planning that works on a weeknight. If you’re new here, The Sunday Prep Plan is the best place to start. When I’m not writing, I’m usually testing recipes on two very honest critics: my kids.

Debut fantasy author, first person (about 70 words)

I write epic fantasy about ordinary people caught up in the decisions of kings. The Salt Crown is my first novel and the opening book of a planned trilogy. I’ve been building this world since I was sixteen, and I’m thrilled readers can finally visit it. By day I teach high school history, which explains why my villains always have a reasonable argument. I live in Ohio with my partner and far too many maps.

How your Author Central bio differs from other bios

You will probably need several versions of your bio, and they should not all be identical:

• Back cover or inside flap: very short, usually third person, focused on the one book in hand.
• Author Central: covers all your books under that name and points readers to where to start.
• Social profiles: one or two lines, often first person.
• Press and media kit: a short and a long version in third person that journalists and podcast hosts can paste directly.

Keeping these versions in one place saves a lot of rewriting. A media kit is a natural home for them; our guide on how to write an author media kit explains what else to keep alongside your bios.

Common mistakes to avoid

• Starting with “I’ve always loved books.” Almost every author has. Lead with what you write instead.
• Listing every credential. Choose the one or two that relate to your books.
• Forgetting to update it. Each new release is a good moment to refresh the bio and the “start here” line.
• Using a different name or genre than your books suggest. If the bio and the books do not match, readers lose trust.
• Writing for other authors instead of readers. Industry awards and sales rankings matter less to a reader than knowing what kind of story they will get.

Quick checklist before you save

• The first sentence says what you write.
• There is one reason to trust you on this subject or genre.
• A new reader knows which book to start with.
• There is one human detail.
• No links, contact details, prices or review quotes.
• It fits the length allowed in your Author Central editor and reads well on a phone.

Keep your bios ready for every request

Once your Author Central bio is done, you have the core of every other bio you will need. Save the short and long versions somewhere you can find them quickly, because podcast hosts, bloggers and event organizers will ask for them. Our Author Media Kit Template includes pre-written pages for your bio, book details and interview topics, so everything a host needs is in one file.

Hiring a book publicist is one of the biggest marketing decisions an indie author can make, and one of the hardest to price. Publicists rarely list fees publicly, quotes vary widely, and it is not always clear what you are paying for. That makes it easy to overspend, or to dismiss help that would have been worth it.

This guide explains how book publicists usually charge, what drives the cost up or down, what you should get for your money, and how to decide whether you need one at all. It does not quote a single “average price,” because honest pricing depends on the publicist, the campaign and your book. Instead, it shows you how to get real quotes and compare them.

What a book publicist does

A publicist’s job is to get your book attention you do not pay for directly: reviews, interviews, features, podcast appearances, event bookings and media mentions. This is different from advertising, where you pay for placement. A typical publicity campaign can include:

• Building a media list of outlets that fit your book
• Writing or polishing your press release and pitch
• Pitching journalists, bloggers, reviewers and podcast hosts
• Sending review copies and following up
• Booking interviews and events, and preparing you for them
• Reporting on what was pitched and what was secured

What a publicist cannot do is guarantee coverage. Media outlets decide what they cover. Be cautious of anyone who promises specific placements for a fee, because that usually means paid placement rather than earned publicity.

How book publicists charge

Monthly retainer

Many publicists charge a fixed monthly fee for a set period, often several months around your launch. You pay for their time and effort each month, regardless of how many placements result. This is the most common model for full campaigns.

Flat campaign fee

Some publicists offer a defined package, such as a launch campaign of a fixed length, for one price. Packages make budgeting easier, but read carefully what is included and what counts as an extra.

Pay for placement

A smaller number of services charge only when they secure coverage, with a set price per interview or feature. You know exactly what you pay for, but the price per result is usually higher, and the outlets may be smaller.

Hourly or a la carte

Some freelance publicists will do specific tasks by the hour or per project: writing a press release, building a media list, or pitching a single local campaign. This can be a good fit for indie authors who want to do most of the work themselves.

What affects the price

• Scope. A national campaign targeting major media costs far more than a regional or niche one.
• Length. A three-month launch campaign and a year-long engagement are priced very differently.
• Experience and contacts. Publicists with strong relationships in your genre or industry usually charge more.
• Type of outreach. Traditional media (print, TV, radio) usually takes more effort than blogs and podcasts.
• Your materials. If you already have a polished press release, bios and media kit, less of the budget goes to preparation.
• Extras. Review copies, postage, event travel and design work are often billed separately.

How to get honest quotes

1. Shortlist publicists who have worked on books like yours. Look at the books listed on their websites and check whether those titles got the kind of coverage you want.
2. Ask for a written proposal that includes the fee, the payment schedule, the campaign length, and exactly what they will do each month.
3. Ask what results they consider realistic for a book in your genre with your platform. A good publicist will be candid, even if the answer is modest.
4. Ask who will do the work. At agencies, the person who sells you the campaign may not be the person pitching your book.
5. Ask about reporting. You should receive regular updates showing who was pitched and what came of it.
6. Ask for references from authors they worked with recently, and contact them.
7. Compare at least three quotes before you decide.

Red flags

• Guarantees of bestseller status, specific outlets or a number of reviews
• Pressure to sign quickly or pay everything up front without a clear contract
• Vague proposals with no list of activities or deliverables
• No examples of past campaigns or authors you can contact
• Offers to buy reviews, which can break retailer rules and damage your reputation

Do you actually need a publicist?

A publicist can be a good investment when:

• Your book has a strong media angle, such as expertise, a timely topic or a compelling personal story
• You want traditional media coverage, which is hard to reach without existing contacts
• You have a budget you can spend without expecting it to pay back from book sales alone
• You simply do not have the time to pitch consistently

It may not be the right move yet when:

• It is your first book and your budget is limited
• Your genre sells mainly through retailer ads, newsletters and series read-through, where media coverage matters less
• You have not yet put together basic press materials

The do-it-yourself alternative

Many indie authors start by doing their own publicity, then hire help later for specific tasks. A realistic DIY plan looks like this:

1. Prepare your materials. A short and long bio, a headshot, cover images, a book summary and sample interview questions. Our guide on how to write an author media kit covers each piece.
2. Write a press release with a real angle. Use our free sample press release for a book launch as a starting point.
3. Pitch podcasts and blogs in your niche. These are often more open to indie authors than traditional media. See how to pitch podcasts as an author.
4. Go local. Local papers, radio, libraries and bookstores are the most likely to say yes to a new author.
5. Track everything in a simple spreadsheet: who you contacted, when, and what happened.

Even if you hire a publicist later, this groundwork lowers the cost, because they will not need to build your materials from scratch.

Budgeting tip

Decide on a total publicity budget before you talk to anyone, and decide what success would look like. For example: a set number of podcast interviews, local press coverage, or reviews from bloggers in your genre. Then compare each quote to that goal, not to each other alone. A cheaper campaign that does not reach your readers is not a bargain.

Frequently asked questions

Why don’t most publicists list their prices?

Campaigns vary in scope, length and target media, so many publicists quote individually after learning about your book and goals. Ask for a written proposal so you can compare like for like.

Is pay-for-placement publicity worth it?

It can be useful when you want predictable costs, but check which outlets are included and whether their audiences match your readers. Placement in outlets your readers never see has little value.

Can a publicist guarantee reviews or sales?

No. Earned coverage depends on editors and hosts, and sales depend on many factors. Be cautious of anyone who promises specific results.

What should I prepare before hiring a publicist?

A finished book, cover images, short and long bios, a headshot, a book summary and a clear idea of your audience. Having these ready reduces preparation time you would otherwise pay for.

Start with what you control

Whether you hire a publicist or not, someone will need your bio, cover, book details and talking points. Having them ready makes you easier to book and makes any publicist’s work more efficient. Our Author Media Kit Template gives you an editable, professional kit with all of these pages, so you can start pitching this week. For the rest of your preparation, see our book launch checklist.

A press release is one of the oldest tools in book publicity, and it still has a place in an indie author’s launch. It will not make a newspaper cover your book on its own. What it does is give journalists, bloggers, librarians, bookstores and podcast hosts the facts they need in a format they recognize, so saying yes to you is easier.

This guide explains what a book launch press release should include, how to format it, and who to send it to. It ends with a free sample press release you can adapt for your own book.

When a press release actually helps

A press release works best when there is a reason for someone to care beyond “a new book exists.” Good angles for indie authors include:

• A local connection. Local papers, radio and community sites often cover authors from their area.
• A timely topic. If your nonfiction book or novel connects to something in the news or a seasonal event, say so.
• An event. A launch reading, a library talk or a signing gives media something specific to list.
• An unusual background. A retired firefighter writing thrillers is a story. Your expertise can be the hook.
• A niche audience. Trade publications, hobby blogs and specialist podcasts may be more interested than general media.

If you cannot find an angle, the release can still be useful as a fact sheet to attach to personal pitches. It just should not be blasted to hundreds of strangers.

The structure of a book launch press release

1. Release line. “FOR IMMEDIATE RELEASE” or “EMBARGOED UNTIL [date]” at the top.
2. Headline. One line with the news and the hook. Not just the title of your book.
3. Subheadline (optional). One sentence that adds the second most important detail.
4. Dateline and lead paragraph. City, date, and the who, what, when and why in two or three sentences.
5. Body. Two or three short paragraphs about the book, why it matters now, and who it is for.
6. A quote. One or two sentences from you that sound like a person, not a sales line.
7. Book details. Title, genre, publication date, formats, page count, ISBN, price and where it is available.
8. Event details (if any). Date, time, place and whether it is free.
9. About the author. A short third person bio.
10. Media contact. Name, email, and where to get review copies, images and interviews.
11. End mark. “###” centered at the end signals the release is complete.

Keep the whole release to one page if you can. Editors skim.

Writing tips that make a difference

• Write the headline last. Once the rest is done, you will know what the real news is.
• Write like a reporter, not a marketer. Facts first. Avoid words like “groundbreaking,” “must-read” or “stunning.” Let the angle carry the interest.
• Use third person throughout, except inside your quote. That way an editor can lift whole paragraphs. Our guide to third person author bio examples shows how to keep it natural.
• Make the quote earn its place. Explain why you wrote the book or what you hope readers take from it. That is the line most likely to be printed.
• Do not invent endorsements or numbers. Only include reviews, awards or sales figures that are real and that you can cite.
• Include links to images. A high-resolution cover and author photo save everyone time.

FOR IMMEDIATE RELEASE

Former Harbor Master Turns Fifteen Years on the Water into a New Cozy Mystery Series

Portland author Maya Ortiz launches “The Keeper’s Secret” with a free reading at Harbor Street Library on June 14

PORTLAND, Maine, May 20, 2026: Local author Maya Ortiz will release The Keeper’s Secret, the first book in her Lighthouse Mysteries series, on June 10. The cozy mystery follows retired lighthouse keeper June Calloway as she investigates a disappearance in a small coastal town, drawing on Ortiz’s fifteen years working in Maine’s harbors.

The novel is set in a fictional town inspired by the fishing communities along the Maine coast. Readers who enjoy small-town mysteries with a strong sense of place, gentle humor and no graphic violence will find a new series to follow.

“I spent years watching how harbor towns work: who knows what, who talks to whom, and what never gets said out loud,” said Ortiz. “June is the kind of person those towns depend on, and I wanted to give her a mystery worthy of her.”

Ortiz will celebrate the release with a free reading and signing at Harbor Street Library on Saturday, June 14, at 2 p.m. The event is open to the public.

###

Who to send it to

• Local newspapers and community news sites. Look for an arts, books or community editor.
• Local radio and TV. Morning and community programs often feature local authors.
• Libraries and independent bookstores. Especially if you are planning an event or want them to stock your book.
• Book bloggers and reviewers in your genre. Pair the release with a personal note and an offer of a review copy.
• Podcasts. A release gives hosts the facts, but a personal pitch gets the booking. See our guide on how to pitch podcasts as an author.
• Alumni magazines, trade publications and professional associations connected to your background.

Send it individually with a short, personal email. Paste the release into the body of the email as well as attaching it, because some editors do not open attachments from people they do not know.

Timing

For monthly magazines, reach out two to three months before publication. For newspapers, local sites and blogs, two to four weeks before launch usually works. For event listings, check each outlet’s deadline. Follow up once, about a week later, then move on.

Frequently asked questions

Do indie authors still need a press release?

It is not essential, but it is useful. A clear one-page release gives media, libraries and bookstores the facts they need, and it works well as an attachment to personal pitches.

Should I pay for a press release distribution service?

For most indie authors, personal emails to a targeted list get better results than mass distribution. If you use a service, be clear about where the release will appear and who will actually read it.

How long should a book press release be?

Aim for one page, roughly 300 to 500 words, plus book details and contact information.

Can I send my press release as an attachment only?

Paste it into the email body as well. Many editors avoid opening attachments from unfamiliar senders.

A press release is one part of your press kit

When someone responds to your release, they will usually ask for more: a longer bio, an author photo, a cover image, sample interview questions. Having those ready is what turns interest into coverage. Our guide on how to write an author media kit explains what to include, and our book launch checklist covers the rest of your press preparation.

If you want a ready-made layout, our Author Media Kit Template includes pages for your bio, book details, interview topics and contact information, so you can send a professional kit alongside your press release. And if a host books you, our guide to author interview questions and answers will help you prepare.

One of the first questions authors ask when writing a bio is whether to write it in first person (“I write…”) or third person (“She writes…”). Both are correct. The right choice depends on where the bio will appear and who will read it.

This guide explains when each style works best, then gives third person author bio examples you can adapt, along with first person versions for comparison. If you want to see your own details written both ways, the free Author Bio Generator lets you switch between first and third person with one click.

The short answer

• Use third person for anything someone else will publish or read aloud: book covers, press releases, media kits, conference programs, podcast introductions and guest posts.
• Use first person where readers expect to hear from you directly: your website’s About page, newsletter, and social media profiles.

Many authors keep both versions of the same bio and use whichever fits the situation.

Why third person is standard for press

When a journalist, blogger or podcast host uses your bio, they are introducing you. A third person bio can be pasted straight into an article or read aloud at the start of an episode without editing. If you send a first person bio, someone has to rewrite it, and they may get details wrong.

Third person also reads as more formal and established, which suits book jackets and professional settings. It can feel strange to write about yourself this way at first, but readers are used to it.

Why first person works on your own channels

On your website, newsletter or Instagram, readers have chosen to come to you. Writing “Maya Ortiz loves coastal towns” on your own page can feel distant. “I grew up in a coastal town” sounds like a person. First person builds connection, which is the point of those channels.

Third person author bio examples

All examples below are for invented authors.

Short (one or two sentences)

• Maya Ortiz writes cozy mysteries set in small coastal towns. She lives in Maine with her husband and an opinionated cat.
• Daniel Reyes is a software engineer and the author of the science fiction novel Low Orbit.
• Priya Shah is a registered dietitian and the author of The Sunday Prep Plan, a guide to simple weeknight meals.

Medium (about 60 to 80 words)

Maya Ortiz writes cozy mysteries set in small coastal towns where everyone knows everyone. Before turning to fiction, she spent fifteen years working on the water, which inspired her Lighthouse Mysteries series. The first book, The Keeper’s Secret, introduces retired lighthouse keeper June Calloway and the town that keeps her busy. Maya lives on the coast of Maine with her husband and a cat who supervises every chapter.

Long (about 150 words, for media kits and event programs)

Daniel Reyes is a science fiction author and software engineer whose stories explore how ordinary people live with extraordinary technology. His debut novel, Low Orbit, follows a maintenance crew on a failing space station and was inspired by his years working on systems that cannot afford to go down. Daniel began writing short fiction in college and has published stories in several independent magazines. He is a regular speaker at local library events on the science behind science fiction, and he enjoys talking with readers about what the future of work might look like. When he is not writing or debugging, he hikes with his two dogs and tries, mostly unsuccessfully, to grow tomatoes. Daniel lives in Colorado and is working on his second novel, set in the same universe as Low Orbit.

The same bios in first person

Here is how the medium example changes in first person:

I write cozy mysteries set in small coastal towns where everyone knows everyone. Before turning to fiction, I spent fifteen years working on the water, and that’s where my Lighthouse Mysteries series began. The first book, The Keeper’s Secret, introduces retired lighthouse keeper June Calloway and the town that keeps her busy. I live on the coast of Maine with my husband and a cat who supervises every chapter.

The content is the same. Only the voice changes, and that small shift makes it feel more personal.

Tips for writing in third person

• Use your full name once, then your first name or a pronoun. Repeating your full name in every sentence sounds stiff.
• Use the pronouns you want readers and hosts to use. If you use they/them, write the bio that way so others follow your lead.
• Stay specific. Third person can drift into vague, formal language. Concrete details keep it readable.
• Avoid praising yourself in ways you would not say aloud. “Acclaimed” and “brilliant” sound odd when you clearly wrote the bio. Let facts do the work.
• Keep the tone matched to your books. A humor writer can have a playful third person bio. A thriller writer might keep it tight and atmospheric.

Tips for writing in first person

• Start with what you write, not “Hi, I’m…” The reader can see your name already.
• Do not overuse “I”. Vary sentence openings so it does not read like a list.
• Be warm but focused. A personal detail is good. Your full life story belongs elsewhere.

Where each version goes

Place	Usual style
Back cover or inside flap	Third person
Press release “About the author”	Third person
Media kit	Third person, short and long
Podcast or event introduction	Third person
Amazon author page	Either; first person is common for indie authors
Website About page	Usually first person
Social media profiles	Usually first person

For the Amazon page specifically, see our guide to writing an Amazon Author Central bio. For platform-length versions, see these short author bio examples.

Frequently asked questions

Is it unprofessional to write an author bio in first person?

No. First person is common and appropriate on your own website, newsletter and social profiles. For press and anything someone else will publish, third person is the safer choice.

Should I write my bio in third person if I wrote it myself?

Yes. It is standard practice. Readers and editors understand that authors usually write their own third person bios.

How do I make a third person bio sound less stiff?

Use your full name once, then your first name or pronoun, and include specific, concrete details instead of formal adjectives.

Which bio should I put in a media kit?

Include short and long versions in third person so hosts and journalists can paste them directly. Some authors add a first person version for blogs that prefer it.

Write it once, use it everywhere

The easiest approach is to write one strong medium-length bio, then create a third person and a first person version of it, plus a short and long variation. If you are starting from scratch, our guide to how to write an author bio walks through the process, and our debut author bio examples help if this is your first book.

Once you have your bios, store them where you can send them quickly. Our Author Media Kit Template includes a bio page ready for your short and long third person versions, so hosts and journalists get exactly what they need.

Want to see both styles with your own details? Try the free Author Bio Generator, generate your bio in third person, then switch to first person and compare.

Canva is one of the most popular ways for self-published authors to design a book cover without hiring a designer. It works well for KDP paperbacks, as long as you start with the right dimensions. Most problems with Canva covers come from one mistake: designing at the wrong size, usually the front cover only, without the spine and bleed that KDP requires.

This step-by-step guide shows how to set up a KDP paperback cover in Canva using a free, correctly sized template. You will need your trim size, page count and paper type. With those, our free KDP Spine Width and Cover Size Calculator gives you the exact full cover size and a downloadable 300 DPI template image.

What KDP needs from your cover file

KDP’s cover guidelines set out the main requirements for a paperback cover:

• One PDF containing the back cover, spine and front cover as a single image.
• Bleed of 0.125 inches (3.2 mm) on the top, bottom and outside edges.
• At least 300 DPI resolution for images.
• Text at least 0.125 inches inside the trim lines on the front and back.
• Spine text only if the book has at least 79 pages.
• KDP recommends keeping the file to 40 MB or less, and files over 650 MB will not convert.

The full cover size is calculated as: bleed + back cover width + spine width + front cover width + bleed. The height is bleed + trim height + bleed. The spine width depends on your page count and paper type, which is why you need those numbers before you open Canva.

Step 1: Get your exact cover dimensions

Open the KDP Spine Width Calculator and enter:

• Your trim size (for example, 6 x 9 inches)
• Your final page count
• Your paper and ink type (white, cream, standard color or premium color)

It shows the spine width and the full cover size in inches, millimeters and pixels at 300 DPI. For example, a 6 x 9 inch paperback with 300 pages on white paper has a spine of about 0.676 inches, so the full cover is about 12.926 x 9.25 inches including bleed.

Download the template image from the calculator. It marks the bleed, trim lines, spine and safe areas so you can see exactly where text should go. If you have not settled on a trim size yet, read KDP trim sizes explained first, because changing it later means redesigning the cover.

Step 2: Create a custom-size design in Canva

1. In Canva, choose Create a design, then Custom size.
2. Switch the unit to inches.
3. Enter the full cover width and height from the calculator, including bleed.
4. Create the design.

Do not start from one of Canva’s generic “book cover” templates. Those are usually sized for an ebook front cover only, which is not the same shape as a print wrap cover.

Step 3: Add the template as a guide layer

Upload the template PNG you downloaded and place it on the canvas, stretched to fill the whole page exactly. This gives you visible guides for the spine and safe zones while you work.

Lower its transparency so you can see your design underneath, and lock it so it does not move. When the design is finished, you will delete or hide this layer before exporting. It is a guide, not part of the cover.

Step 4: Design within the safe areas

Remember the layout: the back cover is on the left, the spine is in the middle, and the front cover is on the right.

• Extend background colors and images all the way to the outer edge so the bleed is covered.
• Keep the title, author name, blurb and any important details inside the safe area, at least 0.125 inches inside the trim lines.
• On the spine, keep text inside the spine safe area. KDP’s guidelines ask for at least 0.0625 inches between spine text and the spine edge because printing can shift slightly.
• Leave space for the barcode on the back cover. If you do not provide a barcode, KDP places one on the back cover for you, so keep that area free of important text.
• Use images that are high resolution. A photo that looks fine on screen may be too small for print at 300 DPI.

For the full list of standard sizes and the measurements behind them, see our KDP paperback cover size guide.

Step 5: Remove the guide and export as a print PDF

1. Delete or hide the template guide layer.
2. Choose Share, then Download, and select PDF Print.
3. If your Canva plan offers a CMYK color option, you can choose it. KDP asks for CMYK images and removes embedded color profiles automatically, so expect slight color differences between screen and print either way.
4. Check that the downloaded PDF has the same dimensions you entered.

Canva also has options for print bleed and crop marks. Because your canvas already includes bleed in its size, you do not need Canva to add extra bleed. Crop marks are not needed for KDP.

Step 6: Upload and check the preview

In your KDP paperback setup, choose to upload a cover you already have and select your PDF. Then open the previewer and check:

• No text or important elements are cut off at the edges.
• The spine text is centered and fully within the spine.
• The barcode area does not cover anything important.
• There are no warnings about size or resolution.

Order a proof copy before you launch. Colors and spine alignment are much easier to judge on a printed book than on a screen.

Common Canva cover mistakes

• Designing only the front cover. KDP paperbacks need the full wrap: back, spine and front in one file.
• Using the wrong page count. If your page count changes after editing, your spine changes too. Recalculate before you upload.
• Switching paper type late. Cream paper is thicker than white, so the same book has a wider spine. Our guide to cream vs white paper on KDP shows the difference.
• Text too close to the edges. It might look fine on screen and get trimmed in print.
• Low-resolution images. Stretched or small images print blurry.
• Using elements you do not have the rights to. Check that fonts, photos and graphics are licensed for commercial use on a book cover.

Frequently asked questions

Can I make a KDP paperback cover in Canva for free?

Yes. A free Canva account lets you create a custom-size design and download a PDF. Some features, such as certain export options and premium elements, require a paid plan.

What size should my Canva canvas be for a KDP cover?

It must be the full wrap size: back cover, spine and front cover plus 0.125 inches of bleed on each outside edge. The exact width depends on your trim size, page count and paper type.

Do I need to add a barcode in Canva?

No. If you do not include a barcode, KDP places one on the back cover. Just keep that area clear of important text and images.

Why does my cover look different in print?

Screens display color differently from print, and KDP removes embedded color profiles. Ordering a proof copy is the best way to check colors before launch.

After the cover: get ready to promote

Once your cover is final, you will use it everywhere: on your website, in social posts, and in pitches to bloggers and podcast hosts. Keep a high-resolution front cover image and a 3D mockup ready to send. Our Author Media Kit Template gives you a professional place to present your cover, bio and book details when media requests come in.

Most author interviews, whether on a podcast, a blog or a local radio show, are built from the same two dozen questions. The host wants an easy conversation, and you want to sound clear and confident without sounding rehearsed. The fix is not memorising a script. It is knowing what each question is really asking and having one or two true stories ready to answer it.

This guide walks through the author interview questions you are most likely to be asked, what the host is after, and a simple way to shape each answer. It works for first-time and self-published authors, and it pairs well with a pitch: if you are still lining up shows, start with our guide on how to pitch podcasts as an author.

How to prepare before the interview

Good preparation is mostly small, boring work done a few days ahead. Do these four things and the interview itself gets much easier.

• Write a one-sentence description of your book. Say who it is for and what the reader gets, for example “a cozy mystery set in a Maine bakery for readers who like gentle puzzles”. If you cannot say it in one breath, the host will not be able to either.
• Pick three talking points. Choose three things you want listeners to remember, such as the idea behind the book, one surprising piece of research or your path to publishing. Steer back to them when the conversation wanders.
• Keep a short bio ready. Hosts often read it aloud. If you do not have one, our free Author Bio Generator gives you a short, medium and long version to edit, and our author bio examples show what works.
• Send the host your materials early. A tidy media kit with your bio, book details, headshot and suggested questions makes the host’s job easier. Our post on how to write an author media kit covers what to include.

The questions almost every author is asked

Tell us about your book.

The host wants the hook, not the plot summary. Give your one-sentence description, then add one detail that makes the book specific. Stop after about thirty seconds and let the host ask a follow-up.

What inspired you to write it?

They are looking for a human story. Think of a real moment, such as a conversation, a news item or a question you could not stop asking, and describe it in a few sentences. Specific beats grand every time.

Who is this book for?

Name a reader, not “everyone”. Something like “people who are starting a small business while working a full-time job” tells listeners whether to keep listening, and that is the point.

How long did it take you to write?

Be honest and keep it brief. A real timeline, including the messy parts such as abandoned drafts or a long break, is more relatable than a polished claim. Add what you learned along the way.

What does your writing process look like?

Hosts like concrete habits. Mention when you write, how you plan or avoid planning, and one tool or ritual that actually helps. You do not need an impressive routine, only a true one.

What was the hardest part?

This is a chance to be candid. Pick one real difficulty, say how you handled it, and end on what it taught you. Listeners remember honesty far longer than they remember a humble-brag.

Why did you choose to self-publish?

If you went independent, explain your reasons plainly: control over the cover and schedule, speed, or keeping your rights. Avoid criticising traditional publishing. Describe what worked for you and let listeners draw their own conclusions.

What do you want readers to take away?

Answer with one feeling or one idea, not a list. If a listener remembers a single line from the interview, this is the one you want them to remember.

What are you working on next?

Even if you have no firm plan, say something true, such as the genre or the question you are exploring. It gives the host a natural way to wrap up and gives listeners a reason to follow you.

Where can people find you and the book?

Say your website or main link slowly, then say it again at the end. Keep it short enough to remember, and ask the host to put the full link in the show notes.

Extra questions for fiction and nonfiction authors

Beyond the core list, hosts tend to ask genre-specific questions. If you write fiction, expect to be asked how you build your characters, whether you outline or write by instinct, and which authors shaped your style. Have one or two real examples ready, such as a character who surprised you or a scene you rewrote several times, because stories land better than general statements.

If you write nonfiction, expect questions about your credentials, the problem the book solves and one practical tip a listener can use today. Offering a small, usable idea during the interview, such as a three-step method or a question to ask themselves, gives the host something to share and gives listeners a reason to look for your book.

Harder questions and how to handle them

Not every question is gentle. A few come up often enough that they are worth practising.

• “Why should I read your book over the others in this genre?” Compare on fit, not quality. Describe what your book offers that a particular kind of reader is missing, rather than putting other authors down.
• “Is it based on your own life?” Decide in advance how much you want to share. A polite “parts of it, yes, though the story itself is invented” is a complete answer, and you can steer back to your talking points.
• “What do you say to critics or negative reviews?” Stay calm and brief. Acknowledge that not every book is for every reader, mention what you learned if anything, and move on.
• “How much money have you made?” You are not obliged to answer. A friendly “I would rather talk about what the book has done for readers” is a perfectly good way to pass.

Questions you can offer the host

Many hosts are grateful for a short list of suggested questions, and it gives you some influence over where the conversation goes. Include five to eight questions in your media kit, covering your book, your background and one topic where you have something distinctive to say. Avoid anything that can be answered with a yes or a no, and put your strongest question first. The Author Media Kit template includes a ready-made interview questions page you can adapt, so you are not starting from a blank page.

Practical tips for the day

• Do a short test recording with your microphone, and sit somewhere quiet with soft furnishings to reduce echo.
• Keep a glass of water nearby and a few bullet points in front of you, not a full script.
• Speak a little slower than feels natural, particularly when you give your website.
• If you lose your train of thought, pause. Silence feels much longer to you than it does to listeners, and hosts can edit it out.
• Send a short thank-you note afterwards, with the link to share, and mention the episode on your own channels when it goes live.

Putting it together

You do not need perfect answers. You need a clear description of your book, three talking points, a short bio and a handful of true stories you are comfortable telling. Write a few lines for each question above in your own words, say them aloud once or twice, and then put the notes away. If you want everything a host might ask for in one place, the Author Media Kit template gives you editable pages for your bio, book details, interview questions and contact information. Once your answers are ready, you can start pitching with confidence.

Picking a trim size is one of the first decisions you make for a KDP paperback, and it quietly affects almost everything after it: your page count, your spine width, your cover dimensions, even how the book feels in a reader’s hands. This guide explains the trim sizes KDP offers, how to choose between them, and what changes when you go bigger. When you are ready to turn your choice into exact cover numbers, the free KDP Spine Width & Cover Size Calculator does the math for you.

What “trim size” actually means

Trim size is the finished size of your printed book after the pages are cut, given as width x height in inches. A 6 x 9 book is six inches wide and nine inches tall. It is not the size of your manuscript file, although the two need to match: if you set up your interior at one size and select another in KDP, your margins and layout will not line up the way you planned.

Trim size is also the starting input for your cover. The full cover width is built from the back cover, the spine, the front cover and bleed, so a different trim size means a different cover file. If you want the exact formula, our KDP paperback cover size guide walks through it step by step.

The standard KDP paperback trim sizes

According to the KDP Help page on paperback trim sizes and page counts, the three most commonly used sizes are 5 x 8, 5.5 x 8.5 and 6 x 9 inches. For a black-ink interior, KDP lists these page ranges:

Trim size (inches)	Category	Page range, black ink on white paper	Page range, black ink on cream paper
5 x 8	Standard	24–828	24–776
5.5 x 8.5	Standard	24–828	24–776
6 x 9	Standard	24–828	24–776

Page limits differ again for color interiors and for other paper types, so check the current KDP Help page before you commit, because Amazon can change these numbers. As of this writing, standard-color interiors on white paper are listed at 72–600 pages and premium color at 24–828 pages for these sizes.

What counts as a “large” trim size

KDP treats a trim size as large when it is wider than 6.12 inches (155.5 mm) or taller than 9 inches (228.6 mm). Examples KDP lists include 6.14 x 9.21, 7 x 10 and 8.25 x 11 inches. Large trim sizes are popular for workbooks, journals, textbooks and picture-heavy books, where a bigger page gives you more room to work with.

The practical consequence is that a larger page changes your cover dimensions and, depending on your page count, the spine as well. Always recalculate the cover when you change size; do not reuse a template made for a smaller book.

Custom trim sizes

If none of the presets fit, KDP lets you enter a custom size for paperbacks. The documented limits are a width between 4 and 8.5 inches and a height between 6 and 11.69 inches. Custom sizes are useful for something like a square poetry collection or a compact guide, but they come with a trade-off: readers and bookstores are used to the standard shapes, and your cover and interior both have to be built precisely to your numbers.

How to choose: a practical way to decide

There is no single best trim size. A better question is what your reader will do with the book. These are common conventions, not rules, so treat them as a starting point and look at a few successful books in your own genre:

• Novels and narrative memoir: many authors use 5 x 8, 5.25 x 8 or 5.5 x 8.5, which feel familiar and keep the page count reasonable. Check which sizes are actually available in the KDP trim list before planning around one.
• Non-fiction and how-to: 6 x 9 is a common choice. The wider page handles headings, tables and sidebars comfortably.
• Workbooks, planners and journals: readers write in these, so a larger page such as 7 x 10 or 8.5 x 11 often makes sense, where available.
• Poetry and short books: a smaller or custom size can suit a short manuscript, but remember that very low page counts affect the spine, as covered below.

How trim size affects page count and spine width

The same manuscript runs to more pages at a small trim size and fewer at a large one, because each page holds less or more text. That matters because the spine is calculated from page count and paper type. A manuscript that is 240 pages at 5 x 8 might be closer to 190 pages at 6 x 9, which gives a thinner spine.

KDP publishes the per-page thickness for each paper type, and the cover formula uses it. Two details worth remembering: spine text is only supported once a book reaches 79 pages, and the standard bleed is 0.125 inches. Our cover size guide covers these in more detail, and the KDP Spine Width & Cover Size Calculator applies them automatically so you do not have to do the arithmetic by hand.

A worked example

Say you have a 70,000-word non-fiction manuscript. Typeset at 5.5 x 8.5 it might land around 280 pages. At 6 x 9 the same text could fall closer to 240. If you print on cream paper, the book will be slightly thicker per page than on white paper, so the paper decision interacts with the trim decision. Rather than guess, set up the manuscript at your preferred size, note the real final page count, and then enter it into the calculator with the right paper type. The page count is the number that matters, not the word count.

If you are weighing paper at the same time, the choice between cream and white deserves its own look, and we will cover it in a separate guide.

Common mistakes to avoid

• Choosing a size after designing the cover. Pick the trim size first; the cover depends on it.
• Mismatching the interior file and the KDP setting. If your PDF is 6 x 9, select 6 x 9. Mixed sizes lead to cropped margins.
• Ignoring page-count limits. A very long book may exceed the range for your chosen size and paper, and a very short one may be too thin for spine text.
• Reusing an old cover template. Any change in trim size or page count changes the cover dimensions.
• Relying on memory for KDP numbers. Specifications change. Confirm them on the official KDP Help page when you finalize.

Next steps

Once you have settled on a size, run your page count through the KDP Spine Width & Cover Size Calculator to get your spine width and full cover dimensions. If you also need author-side materials for the launch, such as a bio, our author bio examples for first-time authors and the debut author bio examples are good places to start, and the book launch checklist shows what else to prepare before launch day.

And when the book is ready to promote, a press kit makes it much easier for podcast hosts, bloggers and reviewers to cover you. Our Author Media Kit template gives you a ready-made structure to fill in. You can also read how to write an author media kit first if you would like the basics.

Finally, remember to double-check every size and page limit against the current KDP Help page on paperback trim sizes before you upload, and use the KDP Spine Width & Cover Size Calculator for the final cover numbers.

Not sure how many pages your manuscript will run at a given trim size? Try our free Word Count to Page Count Calculator to estimate your page count and spine width before you commit to a size.

Once your trim size is set, the next choice is paper. Our guide to cream vs white paper on KDP explains how it changes your spine width.

Writing about yourself is harder than writing the book. If you are about to publish your first one, you probably need a bio for the back cover, your Amazon page, your website and a handful of social profiles, and you have no previous titles to lean on. This guide gives you a plan and eight original debut author bio examples you can adapt. If you would rather start from a draft, our free Author Bio Generator builds short, medium and long versions in a few clicks.

What makes a debut author bio different

An established author can list awards and earlier titles. A debut author cannot, and that is fine. Readers of a first book are not looking for a long résumé. They want to know three things: who you are, why you wrote this book, and whether you are a believable guide to its subject. A good debut bio answers those quickly and then stops.

Three habits separate a strong debut bio from a weak one. First, it leads with the connection between you and the book, not with your job title. Second, it uses one or two concrete details instead of a list of adjectives. Third, it is honest. Do not invent credentials or claim a following you do not have. A modest, specific bio reads as more trustworthy than an inflated one.

The simple formula: hook, proof, personal touch

Most bios that work follow the same three-part shape, and you can write each part in a single sentence.

• The hook: who you are in relation to the book. “Maya Ellison writes mysteries set in the fishing towns where she grew up.”
• The proof: the one fact that makes you credible. A relevant job, a place you know well, a course you finished, years spent researching the topic.
• The personal touch: something human and short. Where you live, what you do when you are not writing, or the pet that interrupts your edits.

Put the pieces in that order, keep it in the third person unless the platform asks for first person, and trim anything that does not help a reader decide to trust you. If you want a deeper walkthrough of the framework, read our guide on how to write an author bio for first-time authors. This post is the companion piece: less theory, more examples.

Eight debut author bio examples

Every example below is fictional and written for this guide. Swap in your own details rather than copying the wording, since a bio that sounds like you will always outperform a borrowed one.

1. Debut novelist, no publishing credits

“Daniel Okafor spent eleven years as a hospital night nurse before he started writing the stories he never had time to tell on shift. The Quiet Ward is his first novel. He lives in Leeds with his wife and a very opinionated cat.”

Why it works: the job explains where the story comes from, and the closing line adds warmth without padding.

2. Romance debut

“Priya Nair writes warm, slow-burn romance about people who are bad at timing. She worked in event planning for ten years, which taught her that every wedding has at least one disaster. Second Chance Catering is her debut. She lives outside Toronto and tests every recipe in her books.”

Why it works: it tells the reader the tone of the book in the first sentence, so the right audience knows immediately that this is for them.

3. Fantasy debut

“Tomas Reyes grew up reading maps before he could read novels. After a decade as a land surveyor, he now draws imaginary ones. The Salt Road is the first book in his fantasy series. He is working on book two from a shed at the bottom of his garden.”

Why it works: one unusual detail, the surveyor background, makes the author memorable and fits the genre.

4. Memoir author

“Helen Burke taught primary school for thirty-two years and, after retiring, finally wrote down the stories her family kept asking her to repeat. Chalk Dust and Second Chances is her first book. She lives in Cork with her husband and two retired racing greyhounds.”

Why it works: for a memoir, the author is the proof. Staying plain and warm suits the genre.

5. Non-fiction, expert voice

“Marcus Webb is a bookkeeper who has helped more than two hundred freelancers get their accounts in order. Tax Season Without Tears is his first book. He lives in Manchester and still sorts his own receipts by hand.”

Why it works: non-fiction readers want a reason to trust your advice, so the number and the profession do the heavy lifting. Only include a figure like this if it is true and you can back it up.

6. Children’s picture book

“Amira Hassan is a children’s librarian who has read the same bedtime stories aloud more than a thousand times. Little Fox Finds the Moon is her first picture book. She lives in Bristol with her two young sons, who are her toughest critics.”

Why it works: the librarian detail tells parents she understands what children actually enjoy.

7. Short social media bio

“Debut author of The Quiet Ward. Former night nurse. Tea, cats, and plot twists.”

Why it works: social bios have very little room, so keep the book title, one credibility detail and one personality detail.

8. Author with a day job and no platform

“Sam Liu is a software tester by day and a crime writer by night. His debut thriller, Edge Case, follows a tester who finds a bug that was never meant to be found. He lives in Vancouver.”

Why it works: it does not apologise for being new. It simply connects the day job to the book.

Length: have three versions ready

You will be asked for bios of different lengths, so write them once and keep them somewhere handy. A short version of about 25 to 50 words suits social profiles and conference listings. A medium version of 80 to 120 words fits your book page and back cover. A longer version of 150 to 250 words works for your website, podcast pitches and press requests. Our Author Bio Generator produces all three lengths, in first or third person, which saves time when you are updating several places at once.

Common mistakes in a debut bio

• Starting with “I am a passionate writer.” It says nothing a reader can picture.
• Listing every job you have ever had. Keep only what supports the book.
• Claiming you are “bestselling” or “award-winning” without a real award to name. Readers and platforms notice.
• Writing a bio that is longer than the book blurb. The bio supports the book, not the other way around.
• Never updating it. Revisit your bio after each new release or milestone.

Where your bio will be used

Once the bio is written, it earns its keep across your whole launch. It appears on your book page, your website, your newsletter sign-up and any guest posts. It is also one of the first things a podcast host or blogger reads when you reach out, which is why it belongs in your media kit. If you are building one, our guide on how to write an author media kit shows where the bio fits, and the podcast pitching guide explains how hosts use it. Our ready-made Author Media Kit Template also includes space for your bio, headshot and book details so everything stays in one place.

Quick checklist before you publish

• Does the first sentence connect you to the book?
• Is there at least one concrete detail a reader could remember?
• Is every claim true and something you could prove if asked?
• Have you saved short, medium and long versions?
• Does it sound like you when read aloud?

A debut bio does not need to impress anyone. It needs to be clear, honest and a little human. Draft one version today using the formula above, or start from the free Author Bio Generator and edit the result until it sounds like you.
