But equally important is the top tub length. So go set on a few bikes and get a better idea of what fits. Remember some bikes list their size as Small, Medium, Large and Xlarge.
This is what you have to beware of--I am 5'6" and I have an inseam of 30"-I ride a 51cm- or a Small or Medium in Compact sizing on road bikes--Or a 15 1/2" on the MTB but I can fit on the front or rear of our offroad Tandem that is a Large/medium.
Frame sizing will give you an indication of the size that may fit you and most go by standover height of the frame. WRONG. The important measurement is top tube length- if you must take one measurement as a rule.
Difficult to know on your first bike as to how it should fit but the main thing is does it feel comfortable? Doesn't have to be exact on your first bike as all it will tell you---Is what your second bike should be on size- type and quality.
Sorry if I am putting you off- but you should try and find someone local to you that rides the type of bike that you are thinking of buying to advise you. It could save a few problems and a bit of money.
