I’ve noticed word counts can vary wildly depending on the subgenre and author’s style. Epic fantasy like 'The Way of Kings' by Brandon Sanderson often breaches 400,000 words, sprawling with intricate worldbuilding and multiple POVs. Middle-grade fantasy, like 'Percy Jackson', tends to be leaner at around 60,000–80,000 words. Most adult fantasy falls between 90,000–150,000 words—long enough to flesh out magic systems but not so dense it becomes a doorstop. Self-published works sometimes skew shorter (70,000–100,000), while trad-published debuts aim for 100,000–120,000 to balance cost and reader patience.
Trilogies often expand word counts per book, like 'The Name of the Wind' (250,000+), whereas standalone novels like 'Uprooted' wrap up neatly around 100,000. Pro tip: Kindle’s 'Reading Time' feature estimates length—if it says ‘12 hours,’ that’s roughly 120,000 words. Publishers also have sweet spots; Tor loves chunky 150k+ tomes, while YA imprints like Scholastic keep it tight under 80k.
