I don't really pay attention to length if it's an author or book I know I want.
For an unknown (to me) I'm not going to be happy to pay standard price (say $11 to $14) for what ends up being a short novella. So I don't. I'll wait until it goes on special, put it on my Prime KOLL wish list if it's available that way, or just go without reading it.
Actually, for an unknown author, I'm not likely to pay that much even for a standard length book unless it looks really good to me and has lots of good word of mouth.
