Gem Hats Sizing Guide

Every Gem Hat comes with an elastic sweatband to better serve all head shapes and sizes. 

If you are in between sizes, we always suggest going up a size. If you don't know your head size, scroll down for instructions on how to measure!

Measurements Guide


Grab a tape measurer

If you don't have a soft tape measurer, you can use a piece of string  and a ruler to measure the length of the string. 


Measure the circumference

Place the tape measurer right below the divot on the back of your head, slightly above your ears and around your forehead where the hat will sit. Do this twice and make sure to not pull it too tight. 


Check the size chart above​

Make sure to measure to the centimeter or quarter inch. The average female head size is 56 cm and average male size is 59 cm. Don't worry, we can accommodate sizes 52cm-62cm!
