Go to your lbs they will tell you what size you need

Depends on type of bike length of inside leg plus a load more body measurements. Personally I would research it yourself and not go 100% by what lbs says. I did once and ended up with a bike 2 sizes too small.

These size guides will give you an idea. http://www.tredz.co.uk/sizing_guides.aspx
