In fiction chapters should be not long, and should give a definite break, but also should make the reader want to read on. Chapters should also contain a logical sequence of events that fit together. Like a sentence that is too long is annoying and loses meaning, so can a chapter be too long. All that is a tall order, but its just craftsmanship. My chapters are usually 4,000 6,000 words. I believe readers like a predictable pace.
An ultra-long chapter is ok sometimes; breaking the rules every now and then can work. An ultra-short chapter is fun, but too many of them makes a piece seem choppy. Michael Moorcock wrote a novel based on ultra-short chapters and I hated it.
BTW, how do you post to the entire ping list?
Go to JamesP81’s home page. He has the list there. Copy it (Control+C just in case you didn’t know that shortcut) and then post it in to the to section and go to the town.
I would link it to you but I don't know how.
