Personally, I will refuse to read anything that has chapters short of at LEAST 2,000 words. I can accept a prologue and even an epilogue being shorter, but that is my only exception. I am not in any way, shape, or form, convinced that chapters are acceptable any shorter than that. To me, even 2,000 is too short but I can tolerate it. Any shorter and I automatically shun the story since there is no way a writer can convey a proper amount of detail, description, action and so on in a single chapter, and condense it to be shorter than 2,000 words. As I said, 2,000 words are awfully short to me, but I tolerate it. However, as for the longest? The sky is the limit as far as I'm concerned.
I'm a hardliner on this. Before I get invested in any story, I make sure the author's know this and ask beforehand.
