1. Circumference:
This measures the distance around your head. Starting at the center of the front hairline, place the tape flat against your head, going just above the ear towards the back of the head, keeping the tape at the nape of your neck and going around to the opposite side of your head, just above the opposite ear and returning to the center of the front hairline.

2. Front to nape:
Place the tape at the center of the front hairline, measure directly across the middle top of your head to the nape of your neck.

3. Ear to ear across forehead:
Place the tape at your temple, just in front of your ear, measure from the hairline at the base of your sideburn, go up across the hair line along your forehead to the same point in front of the opposite ear. 

4. Ear to ear over top:
Place the tape from hairline edge at the top of your ear and go directly across the top of your head to the hairline edge at the top of the opposite ear

5. Temple to temple round back:
Place the tape against your head at the front edge of the hairline (temple area), go around the head above the occipital bone to the opposite front edge of the hairline (the opposite temple area).

6. Nape width
This measures the width of the hairline across the nape of the neck. Place the tape at the lowest point on the bone behind your ear (mastoid bone) and measure across the neck to the opposite mastoid bone.
