Surely height is irrelevant – inside leg is more important.
For example, despite brushing 6ft, I only have a 29 inch inside leg, but still ride a large bike, due to having gibbon arms (Size 12 feet probably have an influence too).
I also agree that BB height is a factor, as this affects the overall height of the saddle.
I do wish people would get their head round the fact that bike sizing is not simple and is a factor of not only your individual proportions, but the brand of bike too (an 18 inch frame can be different across manufacturers)
The number of times somebody says “I’m 5ft 10in, what size (insert bike brand/model here) should I get?” is quite astounding, to be honest.
The only real answer is to go and ride the bike(s) that you’re interested in, and probably to get a bike fit.
P.S. When ‘leaping’ onto your bike, try to land on the inside of your thigh, then slide across into the riding position – either that or start a Bee Gees tribute band.
