James Patterson and Robert B. Parker’s are 2 or 3 pages. Any Rand’s run as long as 35. Most writers are somewhere in between. Me, I’m always struggling with knowing when to end a chapter and start the next one.

In my research to find a rule for how long a chapter should be, I’ve discovered there isn’t one. There is no cookie-cutter, one-size-fits-all solution.

Some writers look at a chapter as a short story—each one has a goal for the characters, a miniature plot arc, a climactic moment and some sort of resolution that leads their characters onward.

Some folks put in a chapter break when the POV changes, the scene shifts or time changes. A writing instructor told her class to aim for your chapters to be at least 20 pages long. Other would-be authors count words—somewhere between 4,500 and 5,500 seems to be enough for them.

“there is one fundamental principle for chapter endings: Something should always be amiss.”

In her blog, Gail Carson Levine says there is one fundamental principle for chapter endings: “Something should always be amiss. If one problem has been solved, another should rise from the horizon or come forward from the background.”
