Novel Chapters: Does Size Matter?

In the process of writing my novel series, I began to realize that I was writing incredibly long chapters. Granted, I am still in the the beginning rough draft stage of my novel, but it got me to thinking. How long should chapters be in a novel? Is there a set length that should not be exceeded? Or a length considered too short? What is the acceptable length of an average chapter? I decided to do some research on this topic, and this is what I discovered.
