Measuring Your Head To Determine Your Hat Size
Measure the distance around your head at the position where your hat normally rests. This is done above the ears and across the forehead. You should have someone take the measurements for you to be accurate. Sit in front of a mirror while someone else measures your head. Have them tighten the measuring tap and loosen it a couple of times to determine the comfort level of how you would like your hat to fit. Your head may be between sizes. Do not let that affect the measurement. Hats can be fitted to within a 1/16 of an inch. If you have an existing hat you may want to compare the hat size with the measurement you took.
