What Average Novel Length Do Indie Authors Aim For?

Lots of folks ask me how long a debut novel should be, and I always give a rounded, practical take because the truth is delightfully messy. For adult literary and mainstream fiction, the sweet spot most editors and agents mention is roughly 70,000–100,000 words. Commercial genres swing a bit: mysteries and thrillers often land between 70,000–90,000 words, romances commonly sit around 70,000–90,000, and historicals can drift toward the higher end—90,000–110,000—because of worldbuilding and context. Fantasy and science fiction are the usual outliers: established epic fantasies can easily exceed 120,000 words, but for debut authors it's smart to aim closer to 90,000–110,000 unless you have a very strong, marketable concept. Young adult generally falls between 50,000–80,000 words, while middle grade tends to be 25,000–55,000. Those ranges exist for reasons beyond taste: debut novels are riskier for publishers, and shorter, tighter manuscripts are easier and cheaper to produce, market, and test with readers. That said, there are famous exceptions—books that broke the mold and still succeeded—so these numbers aren’t jailers, just guideposts. If I had one practical tip, it’s to research comparable titles in your intended market, trim ruthlessly for pace and clarity, and let length serve the story rather than trying to hit a magic number. I find that aiming for the lower end of your genre’s range keeps momentum and makes it easier to impress gatekeepers, and I still love the thrill of reading a debut that defied norms and worked anyway.

one thing I've noticed is that the average length tends to be on the hefty side. Most fantasy novels I've read fall somewhere between 80,000 to 120,000 words. That's roughly 300 to 400 pages in a standard paperback format. Epic fantasies like 'The Lord of the Rings' or 'A Song of Ice and Fire' often go way beyond that, sometimes hitting 200,000 words or more. The genre just lends itself to detailed world-building, complex plots, and large casts of characters, which naturally require more space. Shorter fantasy novels do exist, especially in YA or middle-grade categories, but they're the exception rather than the rule.

Novel length is one of those topics that feels straightforward until you start poking at it, and then you realize just how much it varies. There's a very common publishing industry guideline that sits around 70,000 to 100,000 words for a debut adult novel. That range has become a sort of unofficial standard, especially for genres like literary fiction, mysteries, and thrillers, where it seems to hit a sweet spot for production costs, reader commitment, and bookstore shelf expectations. Going significantly under that can sometimes signal a work is more of a novella to agents and editors, while going dramatically over can raise eyebrows about pacing and marketability for a first-time author. Yet, as a reader, you quickly notice how genre completely reshapes those numbers. Epic fantasy and historical fiction are famous for their doorstopper volumes; it's not unusual for books in these categories to start at 120,000 words and balloon to 200,000 or more. Brandon Sanderson's 'The Way of Kings' is a famous example, sitting well over 380,000 words. On the flip side, a lot of contemporary romance or cozy mysteries might wrap up a satisfying story in a tighter 60,000 to 80,000 words. Young adult novels also often trend shorter, frequently landing between 60,000 and 80,000, though the massive success of books like the later 'Harry Potter' titles blew that ceiling wide open. I think the 'average' is useful as a baseline for writers, but for readers, it's more about the reading experience a word count implies. A 30,000-word novella promises a fast, intense dive, while a 50,000-word novel suggests a more developed arc, and anything over 100,000 signals a world you're meant to settle into for a while. The count sets a rhythm before you even turn the first page. My own shelf has everything from slim, potent 40,000-word stories to massive tomes, and which one feels right just depends on the mood I'm in—sometimes you want a sprint, and other times you're ready for a marathon.
