How to measure your head circumference and determine your hat size

 

Use a tailor measuring tape and start measuring from the middle of your forehead.

Take the measurement about one inch above your ears without tightening the tape, as shown below.

Make sure the tape goes over your occipital bone (the small bump at the back of your head).

 

Take note of the exact measurement from a mirror or have someone take note of it for you.

 

A few tips :

 

  • Make the measurement by tightening the tape as you’d like your hat to fit on your head. It’s a matter of your own taste.
  • Take the measurement at least twice to crosscheck.
  • If you fall in between two sizes, choose the upper size.
