For me I have a hard time reading anything less than a 1000 words (that's idiotic I know). I will read any length. But I do have to admit, when the story is very long and I didn't start reading early on (as a WIP) I have a hard to sitting down and starting it. Especially if it hits in the 200k+ range. It isn't that don't love LONG fics, I do, but I kind of feel like I have to have the time to devote to them. I rarely do with RL happening. Anything over 250k is really really hard for me. I just don't have the time.

The long and short of it (see what I did there) is I love all length, but not all the time. Hope that makes sense.
