You can determine your hat size by measuring around your head with a cloth tape measure. Just place the tape around your head, making sure it is about an inch or so above your eyebrows where the hat would settle. Take the measurement in inches to the 1/8th of an inch and convert it to your head size using the chart below.
If you don't have a cloth tape measure, you can use a piece of string or yarn, and then measure it.
