Words to Pages for Authors: Book Length Guide by Genre

September 5, 2026 · 5 min read

The length of your book matters. Too short and readers feel cheated. Too long and you lose casual readers — and spend more on printing. Different genres have different expectations, and meeting those expectations signals to readers (and publishers) that you understand the market.

Word Count by Genre

Literary fiction: 80,000-100,000 words. Commercial fiction (thriller, romance, mystery): 70,000-90,000 words. Fantasy and sci-fi: 90,000-120,000 words (epic fantasy can go higher). Young adult: 55,000-80,000 words. Middle grade: 25,000-50,000 words. Self-help and business nonfiction: 40,000-60,000 words. Memoir: 70,000-90,000 words.

Words to Print Pages

A standard trade paperback fits about 250-300 words per page. A 80,000-word novel is roughly 280-320 printed pages. For ebooks, the page count is less relevant — readers care about reading time. An 80,000-word book takes about 5-6 hours to read at average speed.

Why These Ranges Exist

Genre conventions exist because readers have expectations. A 40,000-word romance feels rushed. A 150,000-word debut novel is a hard sell to agents and publishers — it signals that the author cannot edit. Self-published authors have more flexibility, but straying too far from genre norms affects reader satisfaction and reviews.

Tracking Your Progress

Set a daily word count target based on your total goal and deadline. Writing 1,000 words per day produces a first draft of an 80,000-word novel in about 80 days — under three months. Track your daily output to stay on pace and adjust when life gets in the way.
