I change my chapter lengths as the action increases. Toward the end, as many things are happening simultaneously in different places, I have some chapters that are less than a hundred words long.
I don't shift PoV at all in my story and so far I've only started a new chapter where I felt that a significant enough amount of time has passed since the previous scene - like between days or after a long trip or something along those lines.
Every thread about chapters on this site that I've read basically states that you can break up chapters however you like. My editor, interestingly enough, has a different opinion. She says that, "a chapter is a single unit of tension."
All you have to do is look through any number of published books, whether in fantasy or otherwise, to see that your editor's definition is too restrictive. Some authors take the approach your editor suggests; many others do not. I see more of your editor's approach outside of fantasy than within it.
You know me - I've never met a rule I didn't like
Speaking of which, I went back and found her actual quote, and it was, "a single unit of conflict," not tension as I originally wrote. I don't think that matters a whole heckavalot, but I wanted to be accurate.
Seriously, though, I've found that the advice caused me to focus each chapter around a central theme of a particular conflict. Not saying that everyone should do so, but I like, so far, how it has transformed the way I'm telling my story.
Glad I'm not the only one.I find myself liking shorter chapters more and more. Of course, I like fast pace without a lot of description, so...
My chapters are averaging in the 1000-2000 word range.
