Fantasy, historical fiction, and horror novels are about 15% longer than other genres.
In one case, a fantasy book was in the top 25 best sellers with approximately 42,000 words (less than half of the average length for this category). Word count matters, but rules can still be broken!https://kindlepreneur.com/how-many-words-in-a-novel/I'm sitting at 50k for my fantasy so who knows whats the best.
