If you do not know your hat size, you can find it by using a measuring tape. Place the measuring tape around the widest part of head where the cap is worn. This is usually about one inch above the ears. Be sure the tape is snug, not tight. Covert the measurement to US Hat Size (e.g. 7 1/8) using the chart below.
