Author Bio Generator
A bio for your back cover and Amazon profile
Most authors find their own bio the hardest hundred words in the book. It has to build credibility without bragging, sound like a person rather than a CV, and work in third person. Give a few details below and get both a full bio and a one-line version.
How long should an author bio be?
Eighty to one hundred and twenty words for the back of the book and the Amazon author page. A single sentence under twenty-five words for retail listings, podcast introductions and social profiles. Writing both at once saves you rewriting the same facts five times.
Why third person?
Convention in publishing is third person for book jackets and retail profiles, because it reads as a description rather than a pitch. First person is fine on your own website and newsletter, where readers expect your direct voice.
What if I have no credentials?
Most debut authors do not, and readers do not require them for fiction. What works instead is specificity: where you live, what you did before writing, what draws you to this genre, one concrete human detail. A bio that says something true and particular beats one that claims authority it has not earned.
Should the bio mention my other books?
Yes, briefly, if you have them. It signals that you finish what you start, which matters to readers deciding whether to invest in a series. One clause is enough, not a list.
Frequently asked questions
How long should an author bio be?
Around 80 to 120 words for the back of the book, plus a one-line version under 25 words for listings and profiles.
Should an author bio be first or third person?
Third person for book jackets and retail profiles. First person is fine on your own site and newsletter.
What do I write if this is my first book?
Be specific rather than impressive. Where you live, what you did before, why this genre, one real human detail.
Do I need a photo with my bio?
Not required, but Amazon author pages with a photo tend to feel more trustworthy to browsing readers.
Can I use the same bio everywhere?
The long version can be reused widely. Adjust the one-liner per platform, since a podcast introduction and an Amazon profile emphasise different things.
