HOW TO MEASURE YOUR HEAD
Using a flexible tape measure, measure the widest part of your head, about a finger's width above your ears, above your eyebrows, and around the widest part of the back of your head. Hold the tape firmly, but not too tightly and measure to the nearest 1/8th inch Measure 2 or 3 times to make sure the measurements are accurate.
If you have not purchased a new hat recently, please measure your head to determine your current hat size.
Sizes vary with hairstyle and weight loss/gain.
If your measurement falls between sizes, choose the next largest size.
