Nowadays, many novels are written with short chapters of no more than four or five pages. I guess this is supposed to go along with the limited attention span of today’s readers. However, short chapters create a lot of chapters.
How long should a chapter be? More importantly, how many chapters are too many and what chapter number should the novel end with?
To the first question, I think that chapters are like sentences and paragraphs. Important tools a writer can use to keep the pace of the story and the suspense. I don’t agree with many publishers who think short chapters should be in thrillers to quicken the tempo and longer chapters used in novels such as romance and the literary to slow the pace. I think it really comes down to what is right for the story and a writer should not hold to any nonsense guideline.
Another excuse given for short chapters is that readers need a break from reading. Readers can find a break from reading even with long chapters. At some point, the story has a transition from one event to another, a change of scenery, or the departure/entry of a character. This is where I can stop reading and take my nap.
To the second question, do readers really pay attention to the chapter numbers? They will if they are superstitious, have a need to read only to a certain chapter number, or believe in the ending of odd or even numbers. But, this is another issue.
I just ask the reader not to blame the writer, who probably ended on a chapter number only because that’s where the ending came.
