The table above provides a conversion of our hat sizes in inches and centimeters.
How to determine hat size:
- 1.Measure around your head about 3/4 inch above your ears, where the hat will sit.
- 2.Keep the measuring tape level and snug, without pulling tight.
- 3.If your measurement falls between two numbered sizes, choose the larger size.

No measuring tape? A convenient option involves using a snapback hat and matching your preferred fit to the provided chart.
If your measurement falls in between sizes, opt for the larger size. Adding a bit of padding to the sweatband can always help you attain that ideal fit.
