Measuring for your head size is both an art and a science. To figure out what size you wear, you will need to find a cloth measuring tape. Measure the circumference of your head at the place where you would wear a hat. Take the measurement in inches and refer to the chart below. If you are in between two sizes, choose the bigger size. You can always pad a hat smaller.
Please understand that hats are not unlike other apparel, in that sizes can vary somewhat, depending on how accurate your measurements are. We will do our best, but cannot guarantee that by following these instructions there is an assurance of a perfect fit.
