I'm 5'2', with 30 in "inseam". I use 170mm cranks. It goes more by leg length than size of frame. If you have to use shorter cranks than optimal just in order to not have toe overlap with the front wheel, then the frame is too small for you. But in your case, with 29 in of leg, you're probably borderline where you could use either size of crank, and I doubt that you would find 165 too short.
