STEP 1

Looking in a mirror, start at the center of your forehead an inch above your eyebrows. Gently wrap the string or cloth tape around your head, a finger width distance above your ears, to the most prominent point in the back of your head. Meet at the starting location in the center of your forehead.

STEP 2

Mark the joint. If you are using a string, measure the start and end points.

STEP 3

We recommend measuring three times for accuracy.
