To measure your hat size, wrap a tape measure around your head just above your ears and at the center of the forehead. The tape should fit comfortably – not too tight. Round up to the nearest size. You can also use a piece of string, and then measure it with a normal ruler.

This conversion chart is for both men and women – look here for children’s hat sizes. Please observe that this is only a guide to find your hat size, sizes may vary between different manufacturers.
