Size Chart


To measure your head, place a tape measure around your head about 1/8" above your ear, across the mid-forehead, completely circling your head. Hold the tape firmly, but not too tightly. You are measuring your head exactly where the hat will sit.

Our hats and caps are labelled in 'cm' and 'UK Size'. When comparing your size to other non Bates branded hats, please use the 'Generic Sizing' as a guide only.
