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.
