Measure your head circumference using a soft tape measure. Place the tape around your head, beginning just above your eyebrows and continue all the way around the widest part of your head, keeping the tape slightly above your ears. Where the tape meets is your head size.
22" to 22 1/2" is about the average for women's head sizes, but if your head if smaller or larger, I am happy to work with you to create a hat that will fit you perfectly.
