Measuring for your head size is both an art and a science. You can use a tape measure or a length of string that you will have to hold up to a tape measure to determine the length. Place the string or tape around you head about 1/8” above your ear, across the mid-forehead, completely circling your head. Hold the tape firmly, but not too tightly. Basically you need to measure your head exactly where the hat will sit. If your measurement falls between sizes, choose the next largest size. You can also use a hat-sizing conversion chart to determine your exact size.
