There are two primary methods of measuring your hat size and are based on the style in which you wear your hat. You will need to take both measurements (shown below) and then use the larger of the two
measurements to determine your hat size. Once you’ve received your hat, you can decide on the style you’d like to size your hat to and adjust your hat accordingly.
TIP: If you don’t have a textile measuring tape, use a string or piece of yarn to measure the distance around your head. After you have marked the yarn around your head, lay it out flat on the ground or table and measure the straightened out piece of yarn with a measuring stick or regular measuring tape.
The Traditional Style
This is the traditional style of wearing a hat. The front tip of the hat is low on the forehead, just above your eye brows, causing the hat to sit nearly level with the ground. To measure your head using the traditional style method, measure the distance around your head from the center of the back of the head to the forehead just above the eyebrow as shown below.
