----- How to measure your head - A quick guide -----

A - With a measuring tape, start by the center of your forehead and run the tape around your head, passing by the occipital bone (the bump at the back of your head).
If you don't have a measuring tape, you can also use a string or shoelace, and then measure the distance you've obtained with a ruler.
B - Measure your head from back to front, starting with your occipital bone, all the way to the center of your forehead.
C -  Start the tape line where the edge of your hat will sit to the same point on the opposite side of your head near your ear.
