My chapter lengths are oddly uniform. Apart from the prologue, which was one and a half pages, Chapters 1 to 9 were all very close to eight pages. Then came Chapter 10 which ended up being twelve pages, and since then all chapters have come very close to that number instead. The more dialogue-filled ones are probably shorter than they look, though, due to all the extra line-spacing that there isn't so much of in a description-filled chapter.
