Welcome to JT.
In addition to being a writer, I'm a bit of a math nerd. I record the length of each chapter of each of my books. Here are the statistics from my first three novels (a trilogy), showing the minimum, average, and maximum number of words per chapter:
1st novel: 551 - 2,401 - 4,836
2nd novel: 695 - 2,161 - 4,128
3rd novel: 1,060 - 2,893 - 4,977
I may not be a good role model to follow but I hope you find some comfort from my sharing this information.
