Hat Sizing Guide

When measuring your head always measure to the nearest whole centimetre. When ordering a hat we advise to size up to the nearest cm. Measuring in centimetres, rather than inches, also provides a more accurate head size.

Generic sizes are approximate sizes, where possible we will give more accurate sizes in the product description.

If you find a hat is very slightly too big, and the next size down is too small, sometimes either stuffing the sweatband with a bit of felt or stitching a pleat in the sweatband will help.
