It really depends on the medium and genre! For novels, I've noticed chapters often land between 3,000–5,000 words. Fantasy tomes like 'The Name of the Wind' sometimes stretch to 7,000+, while YA or thrillers like 'The Hunger Games' keep it tight at 2,000–3,000. I love how pacing affects this—longer chapters build immersion, but shorter ones create that 'just one more' binge-read effect.
Manga and comics are a whole different ballgame. A single chapter might be 20–50 pages with minimal text, relying on visuals. Web serials? They vary wildly—some authors post 1,000-word updates daily, while others craft 10,000-word monthly epics. It’s fascinating how format shapes storytelling rhythm.
