Measure the size of your belt in the following way:
Take the measurement from the buckle and out to the hole in the middle. This measure will be about the same as your waist.
Find your hat size by measuring your head with a measuring tape. You measure horizontally around the head over the middle of the forehead, where the head is widest. Do not tighten the measuring tape too hard. If you get measurements between two centimeters, choose the highest one.
