How to measure your head for the right fitting hat…
To measure your head for a hat, you can use a flexible measuring tape to measure the circumference of your head just above your eyebrows:
Place the tape measure around your head, slightly above your ears.
Make sure the tape measure is snug but not too tight.
Bring the tape measure around to the back of your head.
Measure yourself 2-3 times to be as accurate as possible.
If your measurement falls between two sizes, always go up.
Different manufacturers build their hats differently, and fits vary with a hat’s rigidity features.
