Hat and Cap Size Charts

Fitted Cap Sizes

Fitted caps have fabric that wraps entirely around your head (no snaps, straps, buckles, or velcro). Fitted hat sizes vary and it is important to measure your head to get the most comfortable fit.

Hat sizes are U.S. hat-size numbers, not head circumference in inches. Measure your head and check the listing for the specific style, because fits can vary. See how to measure your head.

Below are different fitted sizing options to help you in your selection process.
