Find Your Hat Size

To determine your correct hat size, you need a measurement of your head.

Measure your head about one-half inch above your eyebrows where your hat will rest using a tape measure. Be certain that the tape measure is not twisted.
You can also use piece of string to measure your head, and then measure the length of the string with a ruler. Buy the larger size if you are not certain about size, or are between size.
 
Use the chart below to determine your hat size based on the measurement you take.
