How to measure your correct Hat size?

Time needed: 2 minutes

How to measure your perfect hat size is explained in simple steps.

  2. To measure your head size you need a measuring tape and a mirror.

  3. Hold the measuring tape against the back of your head.

  4. Pull the measuring tape forward on either side of your head slightly above your ears and your eyebrows to the center of your forehead.

    As a tip, you can use the thickness of 1 finger above your ears

  5. Do not pull the centimeter too tight.

  7. Use the head measurement in inches or centimeters and convert it into the desire hat sizing system

Hat sizing tips – Size-Charts.com

  • We always recommend rounding up the length slightly to a round number (e.g. from 57.5 to 58 cm).
  • If you prefer to wear your hat, cap or hat a little deeper over your head, then add 1 cm or 1/8 of an inch.
  • Ladies are advised to comb their hair back (see picture below).
  • If you don’t have a measuring tape to hand, determine your size with a string and measure it with a ruler.
  • A hat or cap that is too small causes a headache. If a hat is a little too big, it can be compensated with two cork strips. The right hat size matters!
