Hat Sizing Chart: How to Measure Your Head and Find Your Hat Size

Get the perfect fit every time—measure once, shop confidently, and enjoy hats that feel as good as they look. Finding your correct hat size is the key to all-day comfort. A properly fitting hat should feel snug but not tight, sit securely without slipping, and never cause pressure or headaches.

How to Measure Your Head for a Hat

Measure your head where you want the hat to sit—generally just above your ears and eyebrows.

  • Use a soft measuring tape for the most accurate result.
  • No tape? Use a string, mark the length, then measure it on a ruler.

How to measure you head

Measure your head where you want the hat to sit; generally, above your ears and eyebrows. If you don't have a measuring tape handy, you can use a string, then measure the string on a ruler.

This hat size chart includes measurment in inches, centimeters, fitted hat sizes, and size ranges for easy fit, stretch fit and one size fits most hats.

If your measurement falls between two sizes, choose the larger size. You can adjust it with a size reducing tape.

"One size fits most" women's hats are generally 57 cm,  medium. Men's one size hats are 59 cm, large. We will often note if a style "runs larger" and up to what size it will fit. 

Sizes can vary some by brands. Fit and feel can change based on the material of the hat (soft or stiff structure), inner band type (elasticized, cotton, leather), style of the hat, or how you wear your hat (if for example you like to wear your hat tilted back measure your head on that path). A properly fitting hat should be snug but not too tight, and should sit comfortably on your head without slipping or causing discomfort.
