My
Bookshelf is messy but reliable, and over the years I’ve scribbled down word-counts for everything I read — it’s my little librarian’s cheat-sheet. For most adult literary fiction novels I’d say the average hovers around 80,000 to 110,000 words; think of classics like '
Pride and Prejudice' sitting near the upper middle of that
range. Contemporary thrillers and general commercial fiction often live between 80,000 and 100,000 words, while big psychological thrillers and some doorstopper crime novels can push 120,000 to 150,000 — '
gone girl' is a reminder that
popular books sometimes break the mold.
Fantasy splits into personalities: epic fantasy usually averages 120,000 to 180,000 words (debuts often aim for 100,000–140,000 but series can balloon past 200,000), whereas
urban fantasy and fantasy with modern pacing trend 80,000 to 110,000. Science fiction generally sits around 90,000 to 130,000 for mainstream works, with space opera leaning toward the higher end. YA novels prefer tighter storytelling — typically 50,000 to 80,000 words — and middle-grade tends to be 25,000 to 50,000. Picture books are tiny in comparison, often
300 to 1,000 words.
Nonfiction varies wildly: memoirs and popular history/pop-
science books often fall between 60,000 and 100,000 words; practical self-help and business books can be shorter, 40,000 to 80,000.
novellas live in the 20,000 to 40,000 area, and short story collections depend on story lengths but commonly total 30,000 to 70,000 words. Graphic novels are best measured in pages rather than words, but most single-volume graphic novels contain far fewer words than prose novels. I keep these ranges in mind whether I’m reading, recommending, or drafting my own projects — they’re guidelines more than rules, but handy ones nonetheless.
