i just picked up a bike yesterday t obuild up for my gf who is 5'5 or so pretty normally proportioned. its a raleigh capri about 15 years old. 19" seat tube (center of bb to top of the tt) and a 29.25 inch standover with 27"wheels. she says her inseam is 30 inches so well see how it fits her. look for something in that range would be my suggestion
