How to Measure
To determine the correct size, use a tape measure to measure the circumference of your head by wrapping the tape around your forehead and the back of your head. It is easier and more precise if you have a second person to help you. Make sure the tape measure is NOT too tight or too loose around your head when measuring.
Head Circumference: Measure around the largest part of the head; about one inch above the eyebrows.
