Pick up the nearest book. Whether it’s fiction or non-fiction, it’s almost certainly split into chapters.
As readers, we take that for granted. Chapters give us an easy way to discuss where we’ve got to in a new book (“I’m on Chapter 10 now…”) – and provide handy stopping points in the text where we can put the book down.
As writers, though, chapters can be surprisingly tricky.
How many should you have? How long should they be? Do you even need chapters at all?
