Everyone is different - No matter if you are the same height, different parts of your body will be longer and shorter than another person. Its not like a production line and if we are the same height then we are the same lengths. Everyone is different - I am 5ft 11ins and my inside leg is 34ins.
I'm 5'7" and my inside leg is 32", and my partner at 5'8" has 30" inside leg - I agree with everyone else - you will get different answers from everyone, there is no real answer.
