Size Chart

Using a tape measure, measure the widest part of your head (just above the ears and eyebrows) to the nearest 1/8th of an inch.

If you have not purchased a new hat recently, please remeasure your head, as sizes may change depending on hair style, weight loss/gain, and age.

Please also keep in mind that hat sizes vary depending on the manufacturer, so if you are unsure of which size to order, please contact us on and we’ll be happy to advise.

If you are in between hat sizes, try this cotton sizing to make adjustments at home.
