    It way off with me it says i should be on a 56cm frame when a 53 fits me perfectly and it says i should 170 cranks.

    The guy i paid to do my bike fit was way off according to this.

    I found it on the internet so it has to be right!!?????:o

    Works for me, 31.5 inside leg and tells me a 54cm square frame is the way to go!

    Compact size was a little off though.

    There's one at competitivecyclist.com. Their server seems to be acting up at the mo' so I can't give an exact link. It goes in to a lot more datail including instructional videos on how to take your measurements. Baring in mind that every model of bike is different it's quite handy to have these. At the end it will suggest 3 sets of size ranges for a Competive Fit, Eddy Fit and French Fit.

    Many, many years ago I did a thesis on determining the correct frame size. Many thousands of words, numerous diagrams and endless formulae and I came to the conclusion that the most scientific way to determine correct frame size is to look for the one you feel most comfortable on. No 2 people are alike, upper leg length, lower leg length, length of back and suppleness of muscles all determine frame comfort. This is what most formulae overlook.

    I agree however if one is to buy online without being able to fully inspect the frame beforehand it's handy to know such measurements. If they already cycle then they should already have an idea for what fit should suit them.

    The ebicycles calculator is telling me 53cm and I should also consider 52cm, 54cm, 55cm, 56cm, 57cm, 58cm
    So I should be ok on a 52....or a 58 :confused:

    the ebicycles.com calculator I presume?

    The calculator at competitivecyclist.com should throw recommendations for pretty much all dimensions of a frame.

    Of couse, these are only guidelines. If one is without physical injury or deformity their body should be able to adapt to whichever frame they choose so long as its dimensions are somewhat suitable to begin with.
