For Self-Publishing Authors, How Many Words Is The Average Book?

If you're plotting a first indie novel, treat word count like part of the recipe: it changes the flavor more than it changes the fact that you baked something. My tactical guideline is to research ten books similar to the one you love and calculate their average. For many self-published authors that turns out to be roughly 65,000–95,000 words for adult commercial fiction. Romance often sits in the 60k–90k range, thrillers and mysteries around 70k–100k, while epic fantasy usually needs 100k+ to breathe.

Practical notes I tell people: shorter books are faster to edit and launch, which is great if you plan to publish a series. Longer books can justify higher prices and feel more immersive, but they demand stronger plotting and more rigorous pacing. Nonfiction's flexibility is a blessing—focus on usefulness rather than hitting a magic number. If you want a landmark reference, 'Harry Potter and the Sorcerer's Stone' is a mid-length read (roughly in the 70k–80k neighborhood), which shows you can be both commercially huge and not overbloated.

At the end of the day, market expectations matter, but authenticity matters more: write what the story needs and then trim. When I aim a book at readers I try to imagine handing it to someone on a commute — that mental image helps me decide whether 80k feels roomy or cramped.

Books I've seen self-published run the gamut, but if you're trying to pin down an average, think in ranges rather than a single number. From my experience browsing indie shelves and helping friends edit, a typical self-published novel often lands between 60,000 and 90,000 words. That band covers a lot of contemporary fiction, romance, thrillers, and many commercial titles because it balances pacing, production cost, and reader expectations. On the shorter end you'll find novellas and some YA or cozy mysteries sitting around 20,000–50,000 words; on the longer end, epic fantasy and dense sci-fi frequently push beyond 100,000 words and can go up to 150,000 or more.

Genre matters more than whether a book is self-published or traditionally published. For example, middle grade tends to be 25,000–50,000 words, YA around 50,000–80,000, and adult fantasy often expects 90,000+. Nonfiction is a different beast — practical guides and niche how-tos can be 30,000–60,000 words, while narrative nonfiction might be longer. I also notice many indie authors aim for that sweet 70k–90k window because it's comfortable for readers, easier to edit, and cheaper to produce in paperback formatting.

If I were picking a target for a first indie release, I’d pick a genre-appropriate goal and edit mercilessly to hit it; fluff is costly and hard to justify to readers. Personally, I gravitate toward tight, focused reads around 80k, but I adore sprawling 150k epics when the world and characters earn every page — each book finds its own rhythm, and that’s half the fun.

Dependence is the short truth: it depends on genre, audience, and how you plan to publish. I keep a quick mental chart: middle grade 25k–50k, YA 50k–80k, adult commercial fiction 60k–100k, and epic fantasy north of 100k. Self-publishing gives you flexibility, so some indie authors deliberately choose 40k–50k novellas for faster releases, while others craft 120k doorstoppers because their readers love depth.

What I find most useful is thinking of word count as a promise to the reader: the length implies pacing and commitment. If you write a cozy mystery, readers expect a tighter, faster pace; if you write high fantasy, they expect worldbuilding and space to breathe. I usually recommend modeling after comparable titles and then trimming anything that doesn't serve the plot or voice. For me, that approach keeps the book honest and the page turns real — feels right every time.
