How To Find Your Size
Use a cloth or paper tape measure to measure around your head. For best results, use a plastic/cloth tape measure. Alternately, you may use a piece of string or cord and then measure the length of the cord.
Measure across your brow (approx 1″ above eye brows), slightly above your ears keeping the tape parallel to the floor. This measurement is a “two-person” event and is nearly impossible to accurately do by yourself..
