Before you buy
Measure once, size everything
Grab a soft tape measure and take five numbers: chest, waist, foot length, head circumference and hand width. With those in hand, every chart above will point you to the right size in seconds. Cycling kit is cut close, so a measurement always beats guessing from your usual clothing size.
Sizing still varies from brand to brand, so treat each chart as your starting point and cross-check the maker's own guide before you order. When you are on the boundary between two sizes, the fit notes on each page tell you which way to round.
