How to measure your hat size
HOW TO FIND YOUR HAT SIZE
1. Pull a fabric tape measure or length of string around your head just slightly above the ear, across the mid-forehead, completely circling your head.
2. Hold the tape firmly, but not too tightly. You are measuring your head exactly
where the hat will sit in either inches or centimeters.
3. If your measurement falls between sizes, choose the next largest size.
