How to Write an Author Bio: Step-by-Step Guide With Templates

By the Inkora team · Oct 26, 2026 · 10 min read

An author bio is a short paragraph, usually written in the third person, that tells readers who you are and why they should trust you with their time. Write a long version of about 150–250 words first. Then cut it to a short version of 50–100 words and a one-line version, so you have the right length for Amazon, your back cover and the "About the Author" page.

The steps below take you from a blank page to three finished versions, with templates you can fill in.

What do you need before you start?

Gather these before you write. It takes 15–20 minutes and makes the writing much faster.

  • Your book's genre and audience. A cozy mystery bio and a tax-planning bio need different details.
  • A list of credentials. Include jobs, qualifications, years of experience, awards, publications and relevant life experience. Write everything down, even if it feels small.
  • Two or three personal details. Where you live, a hobby, a pet, a habit that connects to your writing.
  • Your other books, if any. Use exact titles, spelled correctly.
  • Where readers can find you. Your website or newsletter name, if you have one.
  • Two or three bios you like. Pick authors in your genre. Note what they include and what they leave out.

Step 1: Decide which versions you need

Most authors need three lengths. Write all three now. You will avoid rushing one at the last minute when a form asks for it.

Version Typical length Where it's used Point of view
One-liner 1 sentence (15–30 words) Social profiles, guest post bylines, podcast intros, anthology credits Third person
Short bio 50–100 words Back cover, retailer author fields, press kits Third person
Long bio 150–250 words (or more) Amazon Author Central, your website "About" page, "About the Author" page in the book Third person, sometimes first person on your own website

These lengths are common working ranges, not store rules. Each platform sets its own limits. Amazon Author Central, for example, has a maximum bio length, so check the current limit on the bio form before you paste your text in.

Step 2: Choose first or third person

Use the third person ("Maria Lopez writes…") for almost everything connected to your book. Here's why:

  • It reads as if a publisher wrote it. That is what readers expect from book jackets and store pages.
  • Other people can reuse it without editing. Podcast hosts, event organizers and bloggers often copy a bio as-is.
  • It makes it easier to state achievements without sounding like you're bragging.

First person ("I write…") works on your own website, in a newsletter welcome email, or in a casual "About me" section. Pick one point of view per version and stick to it. Switching from "she" to "I" halfway through is one of the most common bio mistakes.

If you want a refresher on how first and third person read differently, see what point of view means in writing.

Step 3: Sort your raw material into four buckets

Take your list from the prep stage and sort each item into one of these:

  1. Authority. Why you can write this book. Credentials, experience, research, lived experience.
  2. Track record. Other books, awards, publications, notable press.
  3. Personality. One or two human details that make you memorable.
  4. Next step. Where readers can find more of your work.

Then cross out anything that doesn't serve the reader of this book. A fantasy reader probably doesn't need your accounting degree. A reader of your small-business tax guide does.

Step 4: Write the long version first

It is easier to cut than to expand, so start long. Use this order:

  1. Opening sentence: your name, what you write, and who it's for.
  2. Authority sentence(s): the strongest reason a reader should trust you.
  3. Track record: previous books, awards or publications, if you have them.
  4. Personal detail: one or two lines, ideally connected to the book's themes.
  5. Closing line: where you live or a call to action (website, newsletter).

Write in plain sentences. Use specific nouns instead of adjectives. "Former ER nurse of 12 years" tells the reader far more than "passionate healthcare professional." Only use numbers that are true for you, and be ready to back them up.

Read it aloud when you finish. If any sentence would make you wince when a stranger reads it to you at a book event, rewrite it.

Step 5: Cut it down to a short bio and a one-liner

Now trim the long version.

For the short bio (50–100 words):

  • Keep the opening sentence and the single strongest authority point.
  • Keep one track-record item, or none if you're a debut author.
  • Keep one personal detail.
  • Drop the list of hobbies, the full career history and most adjectives.

For the one-liner:

Use this formula: [Name] is a [credential or genre] author of [book or type of book] who [one distinctive detail].

Example structure: "[Name] is a former high school chemistry teacher who writes funny science books for curious kids."

Step 6: Build credibility in a non-fiction bio

Non-fiction readers buy expertise. Your bio has to answer "why should I learn this from you?" within the first two sentences.

Credibility can come from several sources. You don't need all of them:

  • Professional experience: your role, how long you've done it, and the kind of problems you've solved.
  • Formal qualifications: degrees, licenses, certifications, but only those relevant to the book.
  • Results: concrete outcomes you can verify, such as "has helped hundreds of families plan home renovations." Only use claims you could prove if asked.
  • Lived experience: for memoir, health, parenting or recovery books, personal experience is the credential. Say it plainly. See how to write a memoir for more on framing lived experience.
  • Teaching or speaking: workshops, courses, conference talks, columns.
  • Recognition: media features, awards, or professional bodies you belong to.

A few non-fiction rules:

  • Lead with what's most relevant, not what's most impressive. A PhD in physics matters less for a gardening book than 20 years of growing vegetables on clay soil.
  • Don't inflate. Readers and reviewers check. A bio that oversells hurts you more than one that undersells.
  • Connect your credential to the reader's problem. "She spent a decade cleaning up messy small-business books, which is why this guide starts with the five mistakes she saw most often."

If you're still writing the book itself, how to write a non-fiction book covers how to set up your authority inside the text, not just in the bio.

Step 7: Adjust the tone for fiction

Fiction bios can be lighter. Readers care less about credentials and more about whether you'll tell them the kind of story they enjoy. Good fiction bio material includes:

  • The genre and tone you write ("dark, twisty thrillers," "small-town romance with big families").
  • A personal detail that matches the books, like a historical novelist's love of old maps.
  • Other books in the same genre or series.
  • Where you live, especially if your setting draws on it.

Match the bio's tone to the book's tone. A horror author's bio can be a little eerie. A rom-com author's can be playful. Keep it readable even then. Jokes that need context fall flat for strangers.

Author bio templates you can copy

Fill in the brackets, then rewrite in your own words so it doesn't sound templated.

Short non-fiction bio template

[Name] is a [job title or credential] with [length of time or type of experience] in [field]. [He/She/They] has helped [type of people] [achieve a specific result]. [Book title] is [his/her/their] [first/second] book. [Name] lives in [place] with [family/pet/detail] and shares more practical advice at [website or newsletter name].

Short fiction bio template

[Name] writes [adjective] [genre] about [type of characters or themes]. [He/She/They] is the author of [titles or series name]. When [he/she/they] isn't writing, [Name] can be found [specific hobby or habit linked to the books]. [He/She/They] lives in [place].

Debut author bio template

[Name] is a [current job or role] who has spent years [relevant experience, interest or study]. [Book title] is [his/her/their] debut [novel/book], inspired by [personal connection to the story or subject]. [Name] lives in [place] and is at work on [his/her/their] next book.

Long bio template (website or Author Central)

Paragraph 1: Who you are, what you write, who it's for, and your main credential or genre hook.

Paragraph 2: Your background, meaning the experience, research or life events that led to your books. Include one or two specific details.

Paragraph 3: Track record. Other books, awards, publications, talks.

Paragraph 4: Personal life in two or three sentences, and where readers can find you next.

Step 8: Put your bio where readers will see it

Amazon Author Central

Amazon Author Central is where you claim your author profile, add your bio and photo, and link your books. Your Author Central bio appears on your Amazon author page. Depending on the marketplace, it may also show on your book's detail page.

Steps in outline:

  1. Sign in to Author Central with your Amazon account.
  2. Claim your book(s) once they are live on the store.
  3. Add your long bio (trimmed to fit the current character limit) and an author photo.
  4. Check whether you need to add your bio separately for other Amazon marketplaces you sell in.

Author Central is separate from the KDP book setup, where you enter your book description. If you're setting up the book itself, the Amazon KDP publishing guide walks through that side. Inkora's Publishing Hub also has step-by-step KDP checklists for ebooks and paperbacks, though you upload everything in your own account.

Back cover

The back cover usually holds the book description, possibly a short review quote, and a short bio, often with a small photo. Space is tight, so use your short version. Your blurb sells the book, and your bio supports it. Write the book blurb first, then fit the bio into the space left over.

On a KDP paperback, Amazon places the barcode in the bottom-right of the back cover, per KDP's published cover terms. Keep your bio and photo clear of that area, and confirm the current placement in KDP's cover guidelines. To check your full cover dimensions, use the book cover size calculator. If you build your full-wrap cover PDF in Inkora, the spine width is set from your page count, which helps you see how much back-cover space you have.

"About the Author" page inside the book

This page usually sits at the back of the book. You can use the long version here and end with a direct line to your website or newsletter. Readers who just finished your book are the ones most likely to act on it. For where other pages go, see what front matter is in a book.

Other places

  • Your website's About page (long version, first person is fine)
  • Other retailers' author or contributor fields, such as Kobo, Apple Books and Draft2Digital
  • Guest posts, podcasts, interviews and event programs (short version or one-liner)
  • Press kits (short and long versions together)

Step 9: Test and keep it current

Before you publish:

  • Ask someone who doesn't know you well to read the short bio. Then ask them what you write and why you're credible. If they can't answer, rewrite.
  • Check every name, title and claim for accuracy.
  • Save all three versions in one document so you always paste the latest one.

Update your bio when you release a new book, earn a relevant credential, or change genre. Don't forget to update it everywhere. Old bios linger on retailer pages long after you've changed your website.

Common problems and fixes

"I have no credentials." Use lived experience, research or genuine interest instead. "Has spent ten years restoring old sailboats" is a credential for a sailing novel. For fiction, focus on genre, tone and a personal detail.

"It sounds like a résumé." You've listed too many jobs. Keep the one or two that relate to the book, then add a human detail.

"It sounds like bragging." Switch to third person and replace adjectives with facts. "Award-winning" means little alone. Name the award, or leave it out.

"It's too long for the form." Paste the next shorter version instead of cutting mid-sentence. This is why you wrote three.

"I write in two very different genres." Write a separate bio for each. If you use a pen name for one genre, keep the bios separate unless you want readers to connect them.

"My bio and book description repeat each other." The description is about the book, and the bio is about you. Cut any plot or content summary from the bio.

"I published with an old bio." Update Author Central and your retailer fields now. For the printed back cover, the change takes effect when you upload a revised cover file. Check your platform's rules for updating a live paperback.

Write the long version once, cut it into a short bio and a one-liner, and keep all three in one file. A bio built on specific, honest details will work everywhere you need it, from Author Central to the back cover. Revisit it each time you publish, so it grows with your books.

Frequently asked questions

Should I include a photo with my author bio?+

A clear, recent headshot helps readers connect with you and is commonly used on Amazon Author Central, back covers and websites. Use a well-lit photo that fits your genre's tone, and keep the same image across platforms so readers recognize you.

Can I write an author bio under a pen name?+

Yes. Write the bio as your pen-name persona and include only details you're comfortable linking to that name. Many pen-name authors share their genre, general location and interests while leaving out their legal name and day job.

Should I mention my day job in my author bio?+

Mention it if it adds credibility or interest to this specific book, such as a nurse writing medical thrillers. If it has no connection to what you write, you can leave it out or reduce it to a single phrase.

How do co-authors handle a bio?+

Co-authors usually write either one combined bio covering both people or two short separate bios placed side by side. Agree on the same length and tone for both so neither author looks like an afterthought.

Can I add my email address or social links to my Amazon bio?+

Amazon has content guidelines for Author Central bios, so check the current rules on the bio form before adding contact details or links. Your website or newsletter is usually safer to include in the "About the Author" page inside your book.
