How to find the right hat size?

At JJ Hat Center, finding the perfect fit is easy. Simply measure your head circumference:

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

  • If you haven't purchased a hat recently, we recommend taking your measurements again—changes in hairstyle, weight, or age may affect sizing.

  • Also note that sizes may vary between manufacturers.

  • If you are between sizes, we recommend using our cork strips to adjust the hat to your comfort.
