An author bio is a short paragraph about the writer, shaped for the place it appears: a query letter, a back cover, a website, the line under a guest essay. Most run 50 to 150 words. A good one says what you write, gives the one or two facts that make a reader trust this particular book, and ends on a detail that sounds like a person rather than a résumé.
Below are twenty-five original bios for invented authors, grouped by where they appear, across thrillers, romance, fantasy, literary fiction, memoir, nonfiction and picture books. Each group has notes on why the examples work. The writers, books, journals and prizes are all made up: borrow the shape and use your own facts.
Where your bio goes, and how long
You need more than one bio. An agent, a reader holding your paperback and a podcast host want different things from it, and the length and point of view change with them.
| Where | Person | Length | Lead with |
|---|---|---|---|
| WhereQuery letter | PersonFirst | Length50–100 words | Lead withCredits and experience the book draws on |
| WhereBook proposal | PersonThird | LengthHalf a page to a page | Lead withExpertise, then platform |
| WhereBack cover or jacket flap | PersonThird | Length50–100 words | Lead withWhy you could write this book |
| WhereWebsite, Amazon and Goodreads | PersonThird | Length150–300 words | Lead withYour books, then your story |
| WhereByline under an article | PersonThird | LengthOne or two sentences | Lead withYour book and where to find you |
| WhereSocial profile | PersonFirst or fragments | Length15–30 words, or the platform's limit | Lead withWhat you write |
| WhereIntroduction at an event | PersonThird | Length75–150 words | Lead withShort sentences, written to be read aloud |
Third person is the default for anything someone else will publish: jacket copy, a festival program, a press page. It also lets you state a prize without sounding pleased with yourself. The query letter is the exception, because it is a letter from you, and so is a social profile. A website can carry both: a third-person bio that people can copy, and a first-person note to readers beside it.
One author bio at four lengths
Write the longest version first, then cut. Each shorter version keeps the same order and loses detail, never the credential that matters. Here is one invented crime novelist at four lengths.
Maren Kessler spent eleven years as a fraud investigator for an insurance company in Milwaukee, most of them on fires: warehouses, restaurants, a bowling alley that burned twice in one winter. She learned to read a scene from the smoke patterns and the paperwork, and to tell a family that had lost everything from one that had planned to. Several of her cases ended in court, where she saw how a jury listens to a story. A Fire in Unit Nine, her first novel, grew out of a case she never closed. It follows an investigator who suspects the man she has been sent to help, and can't prove it.
Before insurance, Maren reported for a weekly paper in northern Wisconsin, covering county board meetings, deer season and one memorable cheese theft. Her short fiction has appeared in two crime anthologies. She now writes full time and teaches a night class on investigative interviewing at a technical college. She lives in Milwaukee with her husband, two teenagers and a smoke detector that goes off whenever anyone makes toast. Her second novel takes place during a single night shift at a grain elevator, and is due out next year.

The fire investigations survive every cut because they are the reason to trust this book. The color goes first (the bowling alley, the cheese theft), then the newspaper job and the anthologies. The smoke detector stays as long as there is room: it is the line a reader will remember.
Author bio examples for query letters
The query bio comes after the pitch and the book details, just before your sign-off. It is in the first person and usually 50 to 100 words, the range Jane Friedman's query letter guide gives. An agent working through the slush pile reads it for two things: credits they would recognize, and experience that makes you the right person for this book. Name credits specifically, leave out small contests, and never apologize for having none. Friedman goes as far as saying an unpublished novelist with nothing relevant to share can skip the bio altogether.
This is my first novel. I've worked nights as a hospital pharmacist in Columbus, Ohio, for fourteen years, which is where Lena's habit of counting other people's pills came from. I swim a mile before every shift, and most of this plot was worked out in the slow lane.
My short stories have appeared in The Cinder Hill Review, Northlight Quarterly and Ferry Street, and “Low Country” was a finalist for the Marlow Prize, chosen from about 2,400 entries. I teach composition at a community college in Sacramento. I grew up in the Delta, two miles from the levee that fails in chapter nine.
I drove a long-haul truck for twenty-two years, the last nine as an owner-operator, and kept a second logbook in a spiral notebook on the dash. An essay drawn from those notebooks ran in Heartland Weekend last spring and drew more reader mail than anything else the magazine published that year. I now teach defensive driving in Joplin, Missouri, and still can't sleep without road noise.
I'm a certified arborist and have spent sixteen years caring for street trees for a city forestry department in Ohio, where I now run the tree inventory. I write Root Zone, a weekly newsletter about city trees with about 18,000 subscribers, and once a month I answer listeners' questions on a regional public radio call-in show. My article on why street trees die young was the most-read feature on a national gardening site last year.
I've self-published five books in the Hollis Bay cozy mystery series since 2021. Together they have sold about 60,000 copies, and the first has more than 3,000 ratings averaging 4.4 stars. THE WIDOW'S LIGHTHOUSE begins a new and separate series, written for traditional publication. Before writing full time I was a court stenographer in Providence, Rhode Island, which is excellent training for dialogue.
I've taught kindergarten in Tacoma, Washington, for twelve years, which means about 300 five-year-olds have heard my read-alouds, a tough room. GOODNIGHT, LOUD HOUSE came from a student who told me his house was too noisy to sleep in and then listed every sound. I'm a member of SCBWI and a monthly picture book critique group.
Why they work. The pharmacist's bio is a complete answer for a debut: her status, a job that explains a detail from the pitch, one human line. The literary novelist names her journals and gives the prize's entry count, so the agent can judge it. In nonfiction the bio is part of what is being sold, so the arborist's paragraph is credentials and audience numbers. The self-published author mentions sales only because they are strong.
Leave in
- Publication credits, named
- Prizes with real competition, ideally with the number of entries
- Jobs, places and experience the book draws on
- Writing degrees, workshops and professional organizations
- For nonfiction: audience size, columns, shows, endorsements
- One human detail, briefly
Leave out
- How long you have dreamed of being a writer
- Apologies for having no credits
- Vague credits such as “various literary journals”
- Small local contests and honorable mentions
- What your family or writing group thought of the book
- Your blog, unless its audience is a selling point
The bio follows the paragraph with your word count and comp titles. The guide to writing a query letter covers the rest of the letter, and the query letter template gives each paragraph a word budget. For a nonfiction book the bio grows into a full section of the book proposal.
Back cover bio examples by genre
A back cover or jacket flap bio is read by someone deciding whether to buy, usually after the blurb has done the selling. Keep it in the third person and between 50 and 100 words, and match the tone of the book: a romance bio can be warm and a little funny, a thriller bio terse.
Theo Marsh was a court reporter in Baltimore for nine years and typed the testimony of more liars than he can count. Silent Record is his first novel. He lives in Annapolis, Maryland, and still types faster than he talks.
Lucy Adeyemi writes small-town romances with big families, bad weather and at least one dog. She grew up above her parents' bakery in Astoria, Oregon, and can still shape a baguette half asleep. Second Rise is the third Harbor Street novel. She lives in Portland with her husband, who proposed to her in a grocery store.
R. J. Sato designs bridges for a living, which is why the cities in The Tidebound Crown have working drainage. This is his first novel. He lives in Seattle with his partner, their daughter and an unreasonable number of hand-drawn maps.
Nadia Ferrante is the author of the story collection Salt Year, which won the Marlow Prize for short fiction. Her stories have appeared in The Cinder Hill Review and Northlight Quarterly. Born in Trieste and raised in Providence, she teaches creative writing at a state university in Vermont. The Glass Orchard is her first novel.
Jess Tolliver coached high school debate in El Paso, Texas, for ten years and judged more than 2,000 rounds, several of them fairly. Rebuttal is her first novel for young adults. She lives in El Paso with her wife and a retired greyhound who sleeps through everything.
Dr. Helen Ashby is a soil scientist who has spent twenty years studying farmland across the Great Plains, from Texas to North Dakota. Her research on topsoil loss has been cited by state agriculture agencies, and she has testified before two state legislatures. What the Ground Remembers is her first book for general readers. She lives on a small farm outside Lincoln, Nebraska.
Carla Duarte drove a long-haul truck for twenty-two years and more than two million miles. Mile Marker Zero is her first book. She teaches defensive driving in Joplin, Missouri, and still can't sleep without road noise.
Why they work. Each fiction bio has one fact that connects the author to the book (the court reporter and the liars, the engineer and the drainage) and one that is just the person. Debuts say so plainly. The memoir bio is the query bio turned to the third person, with the magazine essay dropped: a reader in a bookstore cares about the two million miles, not the credit.
Website and Amazon author page bios
Your website, your Amazon author page (set up through Author Central) and your Goodreads author profile are where readers go after a book they liked. These bios can run 150 to 300 words and should name your books, newest first. Keep a third-person version on your site that event organizers and reporters can copy, and label it plainly as a bio. The author website examples show where it sits among the other pages.
Annie Brandt is the author of the Juniper Pass mysteries, six novels about a retired park ranger who keeps finding trouble on the trails she used to patrol. The newest, The Switchback, came out this spring.
Annie worked fourteen summers as a seasonal ranger in national parks across the West, from Glacier to Big Bend, and she still spends every August with the trail crew that gave her the idea for the first book. The series began as campfire stories for visitors who asked what the most dangerous thing in the park was. Before the parks, she taught high school biology in Fort Collins, Colorado. Her books have been translated into German and Polish, and The Long Way Down was a finalist for a regional mystery award. She lives in Bozeman, Montana, with her husband and a pack mule named Earl, who appears in book four and has not forgiven her.
Hi, I'm Annie. I spent fourteen summers as a park ranger, which mostly meant explaining to visitors that the elk are not friendly. Now I write mysteries set on the trails I used to patrol. If you're new here, start with The Long Way Down, the first Juniper Pass book. Once a month I send a short newsletter with a true story from the backcountry and news about the next book. It's free, it's short, and Earl the mule makes regular appearances.
The bio is for people who need to paste it somewhere. The note is for readers, and it ends by telling them which book to start with and how to hear about the next one.
Short bios for bylines, profiles and events
The shortest bios get read the most. A byline has a sentence or two to send readers to your book, a social profile has one line, and an introduction at a reading is heard rather than read. For bios outside publishing, such as a LinkedIn summary, see the professional bio examples.
Nadia Ferrante's first novel, The Glass Orchard, is out now. She teaches creative writing in Vermont.
Helen Ashby is a soil scientist and the author of What the Ground Remembers. She writes about farmland in her monthly newsletter, Topsoil.
- Crime novelist. Former fire fraud investigator. A FIRE IN UNIT NINE out now.
- Small-town romance with big families and at least one dog. Harbor Street series, book three out now.
- Soil scientist writing about farmland for people who eat. New book: What the Ground Remembers.
Helen Ashby is a soil scientist. For twenty years she has studied farmland across the Great Plains, from Texas to North Dakota, measuring how fast the topsoil is leaving and where it goes. She has explained it to farmers, to state legislators, and now to the rest of us. Her new book is What the Ground Remembers. She lives on a small farm outside Lincoln, where, she tells me, the soil is in good shape. Please welcome Helen Ashby.
Why they work. The bylines get to the book within a sentence, since the book is the point of writing the essay. The introduction uses short sentences, says the name at the start and the end for anyone who came in late, and leaves out anything that only works on paper, such as parentheses and long titles. Send the host your pronunciation if your name is often misread. The press kit examples show how the short and long bios sit together for reporters.
How to write your own author bio
- Make a raw list
Write down everything that could go in: jobs, places you have lived, publications, prizes, degrees, odd skills, and the reason you wrote this book. Thirty items is not too many. You will use four or five.
- Find the credential for this book
Ask which fact explains why you could write this book. For fiction it is often a job, a place or a community. For nonfiction it is expertise and an audience. That fact goes near the top of every version.
- Write the long version, then cut
Draft about 200 words in the third person, in this order: what you write and your newest book, the credential, other credits, one human detail. Then cut to 100, 50 and 25 words, keeping the order.
- Choose one human detail
Make it specific and true. A pack mule named Earl beats “loves hiking, coffee and her two kids”, which describes several million people. If it echoes the book's tone or setting, better still.
- Fit it to each place, and keep it current
Switch to the first person for queries and social profiles, check the length you were given, and read it aloud. Update every version when you publish something new, and date the files so you know which is current.
Before. Jennifer has loved writing ever since she was a little girl. She has always been passionate about stories and has worked very hard on her craft. When she isn't writing, she enjoys reading, coffee and spending time with her family. This is her first book, and she hopes you enjoy reading it as much as she enjoyed writing it.
After. Jennifer Lowe spent eight years as a 911 dispatcher in Reno, Nevada, where she learned how much can happen in a ninety-second call. Dead Air is her first novel. She lives in Reno with her family and still answers the phone on the first ring.
The first version could be about anyone. The second is shorter and gives a reader three things to remember, one of which sells the book.
If you keep your book in Strokes, put all your bio versions in one document inside the book's project, so the query, the back cover and the website draw on the same facts. Version history keeps last year's bio when you rewrite it. To make a short version, select the long one, press ⌘K and ask for a 50-word cut in the third person, then check that the credential survived.
Frequently asked questions
Should an author bio be in first or third person?
Third person for anything someone else will publish: the back cover, a press page, an event program, a byline. First person for a query letter, which is a letter from you, and for social profiles. A website can carry both: a third-person bio to copy and a first-person note to readers.
How long should an author bio be?
It depends on where it goes. A query letter bio usually runs 50 to 100 words, a back cover bio about the same, a website or Amazon author page bio 150 to 300 words, and a byline one or two sentences. If an agent, publisher or event gives you a limit, use theirs.
What should I write if I have no writing credits?
Say that this is your first book, add any job, place or experience the book draws on, and finish with one specific detail about you. Don't apologize for the missing credits. Agents judge a debut mainly on the pitch, and an unpublished novelist with nothing relevant to share can leave the query bio out.
Should I mention self-published books in a query letter?
Mention them if the sales or ratings are strong, and give the numbers. Otherwise it is your choice. Make clear that the book you are querying is new, since agents rarely take on a book that is already self-published.
Should my bio mention my family, pets or hobbies?
One personal detail is enough, and it works best when it is specific or connects to the book. A list of hobbies reads like a dating profile and uses words you need for credentials.
