  4. Switch tabs to the "Calculate My Size"
  5. Copy and paste or input your head size in inches into the blank field. Once again you can switch to CM tab if you would like to use centimeters instead of inches.
  6. Choose your fit preference - Decide if you want your fitted hat a little loose, a little tighter or just regular.
  7. Depending on your Fit Preference the recommended size will display below.

If your head measurement is smaller than 21.6 inches or larger than 26.1 inches then you will encounter an error (as seen below)

Β This happens because there are no fitted hat size for adult heads of 19 inches. Our suggestion would be to choose 21.6 inches for small heads and for larger heads choose the 26.1 inches. You can always stretch out and shrink your fitted hat to fit your head better. Children head sizes are commonly between 16-19 inches and have specialized New Era fitted hats made for them.
