I never used to really think about it, but when I re-did a couple of my old stories I did split them into chapters rather than large massive oneshots. Seemed easier to read!

This is one of those questions that plague writers everywhere. Readers struggle with it as well.
There is a school of thought that chapters work at anywhere from 3-5k words per chapter. Any longer, and it’s hard to find a stopping point, since most readers don’t have the luxury of reading a book through in one sitting. Any shorter, and you hit the same problem people have with flash fiction in general: how do you convey sufficient information to hold the reader’s attention and make them want to read the next chapter?
Personally, I like 4-5k words per chapter. That’s my comfort level as a writer. As a reader, as long as you hold my attention, I’ll keep reading. I’ve stayed up half the night to finish a particularly engrossing book.
