https://en.wikipedia.org/wiki/Word_count#In_fiction
This Wikipedia page tells you under which classification a fictional work falls under depending on its length, so we have 3 I am most interested in, namely: novellette, novella and novel. We could argue that all of them are novels, so would you agree that the length of a chapter should depend on the length of the novel?
Moreover, how short should the shortest chapter be? I am asking, because sometimes, you write a scene, and you have a hard time adding any relevant information to it and you want to end it as soon as possible. One of my chapters is barely 400 words long, so I was kinda concerned about the length.
