To measure your head for a wig, use a cloth tape measure that has not been stretched for accuracy. 1  Forehead to Nape Start the tape from the center of the front of your hairline, to the hairline at the nape of the neck. If you have little or no hair, lay your index, third, and ring finger flat against your forehead just about at the brow bone. At the top of the three fingers would be a good straight point.
You can use a tape measure (or a length of string that you will have to hold up to a tape measure) to determine the length. Place the string or tape around your head about 1/8 above your ear, across the mid-forehead, completely circling your head. Hold the tape firmly, but not too tightly. Basically you need to measure your head exactly where the hat will sit. If your measurement falls between sizes, choose the next largest size.
