Hat size guide
How to measure your head and find your perfect fit.
How to measure
Wrap a soft tape measure around your head about 1cm above your ears and eyebrows — where the hat will sit. Keep it snug but comfortable and read the measurement in centimetres. If you’re between sizes, go up.

A fit tip from our hatters
Felt and straw hats relax slightly with wear. A new hat should feel snug and secure, not tight. We include a free sizing strip with every structured hat so you can fine-tune the fit.
