I've learned that chapter length depends on the story's pacing and genre. Fast-paced thrillers often have shorter chapters, around 1,500 to 2,500 words, to keep readers hooked. In contrast, epic fantasies like 'The Lord of the Rings' might have longer chapters, sometimes 5,000 words or more, to build detailed worlds. I personally prefer chapters around 3,000 words because they give enough space to develop scenes without losing momentum. It's also important to end chapters on a hook or cliffhanger to keep readers turning pages. The key is consistency—readers notice if chapters vary too much in length.
