Despite the variations in body measurements, the majority of 6' tall people are best off on what would be considered a 58. Going by inseam or body length alone will play against a good fit, because someone with long legs is going to need a shorter top tube, but not a shorter stack. And someone with short legs needs the top tube length. Unless the person's proportions are so far off that they really need a custom, total height is one of the best predictors of frame size.

I've been doing this a long time, but now work at a shop that does the best fittings in the midwest. Our fitter starts with a blank slate, but I have yet to see someone who fits a stock bike and the size wasn't predicted by height. There are always exceptions, but those prove the rule, right?


I wouldn't use pros as examples of how to size a bike. Non-pros shouldn't be concerned with trying to find the lightest, shortest wheelbase, lowest stack frame they can fit on. Bikes fit that way are great for crits, not for all around use.
