HOW ARE HATS MEASURED? 

Hats are measured by the inside circumference at the bottom of the hat's sweat band and is usually measured in centimetres. While hats may be sized according to their measurement, it is fairly common for hats to be sized based on average  head sizes.

HOW DO I MEASURE MY HAT SIZE?

There are two main methods of measuring your hat size and are based on the style in which you wear your hat. The traditional style, where your eyebrows are just visible below the brim at the front of the hat. The halo style is where the hat sits on top of the head at varying angles behind your ears.  Remember there is nothing worse than a hat that is too big that you have to hold onto on a windy day.

TIP:  If you don't have a textile measuring tape, use a string to measure the distance around your head and use a ruler to measure the length of string.
