Advice
Adult fiction
by Stewart Ferris
For most adult novels the safe harbour is 70,000–100,000 words, and 80,000–90,000 is the band that rarely scares an agent. Writer's Digest's long-used benchmark still holds for commercial and literary debuts: 80,000–90,000 is the comfortable middle, under 70,000 is usually too short, and 110,000 or above is usually too long. Genre moves the edges.

Literary and book-club novels cluster at 80,000–90,000. A bestselling author can publish 130,000 words. A debut above about 110,000 is a hard conversation.
Single-title contemporary romance usually lands at 70,000–90,000. Category romance — Harlequin and the other numbered lines — is a different product, often 50,000–60,000, and each line publishes its own target. Historical romance runs longer because the period has to be built. Romantasy has pulled the ceiling up: 90,000–120,000 is now ordinary, but a 150,000-word debut still needs a reason beyond “the world is big”.
Pace is the product in mystery, thriller, and horror. Cozies are the short end, often 60,000–75,000. Traditional mystery and thrillers sit at 70,000–90,000, sometimes toward 100,000 for espionage. A taut horror novel at 70,000–85,000 is easier to sell than a bloated one.
World-building is why science fiction and fantasy run long, not a licence to. For a debut, 90,000–110,000 is the comfortable fantasy band, and 90,000–100,000 in science fiction. Epic fantasy can justify 120,000–130,000 if the cast and the map are doing work on the page. Past that, most agents will ask for a cut before they read. Later books in a series can be longer once the world is already paid for. Historical fiction is similar: 90,000–120,000 is normal, and 100,000 is a sensible debut target. The extra words should be scene, not a lecture.
