This is basically a follow-up question I asked here: Scene switching and how to do it?
I always considered it normal for a chapter to have between 3000 and 5000 words. And people around here thought so too: What is a normal length for a chapter? But the comments I got from my "Scene switching" question recommended way smaller amounts.
I tried looking for a different approach which is read on here: When should a chapter end? The answer I liked most was of "Lauren Ipsum". But it seems outdated?
All this raises some questions.
What is the deal with chapter sizes? How many should I use? Should I be consistent in sizing? Wouldn't variable sizing be annoying to readers?
