Determining your wig size is easy. Simply measure around your head, as shown in the photo. Drape the cloth tape around the back of the head and touch the base of your skull at a point where the wig will end. Position the end of the tape at mid-point of your front hairline, place tape measure as shown, just above ears. This measurement is your head 'circumference'.
