Supposedly you should have 'two fingers' of stand over height, or an inch if you prefer, between the crown jewels and the top tube, but in reality you can have more than that. The more important factors in fit are seat tube, top tube, stem length, and saddle to bar drop. At 175 your cranks are ideal for someone around the 6' mark, but I'm 6'2" and seem to be able to ride cranks from 170-175 without much noticeable difference. Some people seem to have very specific preferences, and others don't. This too applies for what frame sizes one can ride on. At 6'2" I ride a 61c-t and a 59c-t with not much noticeable difference, except a bit more seatpost showing! The more you ride, the more bikes you try, you begin to learn what will or wont fit!
