Author bio generator: build your bio at three lengths

Here's exactly what happens when you type, taken from the code.

The tool has seven sentence slots, each built from your boxes. The opening is "Name writes ...", or "Name is the author of the book" when you give no genre phrase, or "Name is a writer." with only a name. The book sentence reads "She is the author of the book (publisher or year)." Then come earlier books ("Earlier books include ..."), credentials ("Credits include ..."), working life ("She spent ..."), place ("She lives in the place with whom or what.") and website ("Find her at the site."). A full stop at the end of what you type is stripped and put back, so you can type it either way. When your place already contains a comma, as in "Lake City, Colorado", a second comma goes in before "with".

Which sentences land in which length is fixed:

So the short bio never carries your book or your credits. If a retail page needs your book's name, add it by hand.

Each bio is measured against a band: short 15 to 35 words, standard 40 to 80, long 60 to 190. Under the band you'll see "Short even for this one. Another true detail would help." Over it, "Longer than the slot usually allows." Inside it, "Right for the slot." Words are counted by the same function as our word and page count tool, so a hyphenated word or one with an apostrophe counts once.

What it can't do is the longer list. It doesn't rewrite, add style, check facts, choose which credits matter or hear your tone. A template can't make a bio sound like you. The sections below cover what to add by hand.

Every count here came from running the tool's own sentence builder and its word counter. The authors and books are invented for this page, so none of these are real people.

Example A fills all nine boxes: Ana Beltrán (she), who writes historical fiction set in the mountain west; her book The Long Winter Count (Western Reflections, 2027); earlier books Cold Creek and The Quiet Season; a Pushcart nomination and work in Ploughshares; thirty years as a wildland firefighter; Lake City, Colorado, with two badly behaved dogs; and anabeltran.com.

The short version reads: "Ana Beltrán writes historical fiction set in the mountain west. She lives in Lake City, Colorado, with two badly behaved dogs." The long one reads: "Ana Beltrán writes historical fiction set in the mountain west. She is the author of The Long Winter Count (Western Reflections, 2027). Earlier books include Cold Creek, The Quiet Season. Credits include a Pushcart nomination and work in Ploughshares. She spent thirty years as a wildland firefighter. She lives in Lake City, Colorado, with two badly behaved dogs. Find her at anabeltran.com."

Notice that the long version is only 63 words, 13 more than the standard one, and 42 percent of the 150 the side panel talks about (63 divided by 150). It sits just inside its band, and it's still plain. That's the template's ceiling, and it's why the page keeps telling you to write the rest.

Example B is a first-time author with three true facts: Tom Fletcher (he), science fiction, Cardiff. All three versions come out identical, "Tom Fletcher writes science fiction. He lives in Cardiff.", at 9 words, all flagged short. A thin bio is fine. Don't pad it with a made-up credit to turn the pill green.

Example C is a debut nonfiction author: Maria Lopez (she), practical guides for first-time farmers; Forty Acres and a Loan (2027); twenty years as an agricultural lender; Pueblo, Colorado. Short is 13 words, standard 32 and long 32 (there are no earlier books or website to add), and all three are below their bands. The bands assume more input than most debut authors have, so read the verdict as a prompt, not a fault.

The closing point is a simple one: the numbers tell you whether a bio fits a slot. They don't tell you whether it's any good.

Different kinds of writers hit the template differently, so here are four more runs. All four are invented, and every number came from the tool's code.

Priya Nair's standard version reads: "Priya Nair writes picture books about small animals with large problems. She is the author of Otter Needs a Plan (Juniper Hill Books, 2027). Credits include a state library award shortlist. She spent twelve years as an elementary school librarian. She lives in Duluth, Minnesota, with a cat named Biscuit." That's 50 words and it works, because a children's author's working life (a librarian) is exactly what a parent or teacher wants to know. Her long version is 56 words, four short of the long band.

Marcus Hale's pattern is the same. A career as a public defender is the credential behind a legal thriller, and the template places it in the working life sentence. Standard is 48 words and fits. His long version, with two earlier books, lands at 56, still under the long band's floor of 60.

Lien Tran, a poet with a chapbook and three magazine credits, gets 13, 32 and 32 words. All three fall under their bands, and the standard and long versions are identical because she has no earlier books, working life or website to add. Poets often have a brief, true bio, and a bio of 32 words is not a failure. Check what the magazine or press asks for before you add anything.

Walt Pruitt, a local historian, comes in 1 word under the short band, 1 under the standard and 8 under the long band. Close misses like these are where a single true sentence by hand fixes the verdict: a society he belongs to, a talk he gives, a map he surveyed.

The pattern across all seven authors in this section and the one above is simple. Nine boxes of facts produce a bio of about 60 words at most. Anything beyond that is something you write.

• The long bio stops early. With all nine boxes it builds about 63 words. Reaching a website-length bio means writing two to four sentences yourself: why you write about this subject, one specific research or life detail, and where readers can find you or what you speak about.
• The short bio contains no book and no credential. If a retail page needs your book's name, edit it in. For example, "Ana Beltrán writes historical fiction set in the mountain west and is the author of The Long Winter Count." is 19 words and still fits the slot.
• The working life box must start with a length of time, because the tool writes "She spent ...".
• With the name box empty, the tool says "The author" where your name would go, which is a placeholder and not a bio.
• If you leave "What you write" empty but fill the book and a year, you'll get a clumsy sentence such as "The Long Winter Count was published by 2027." Fill the genre phrase and the tool writes the book sentence properly.
• Nothing is fact-checked. The spelling of your book's name and your publisher is whatever you typed.
• Don't claim awards you can't back. A false line in a bio travels farther than you'd think, since it gets copied to every platform that carries your name.

Lengths differ by place, so keep all three versions on file. This table pairs each place with the version that usually fits and what a source says about its length. Sources are linked where used, and the tool's bands are the tool's own.
