Before you start: Pin hair as flat and as tight as possible before taking the measurements. Cornrowing your hair is also an excellent method of condensing it as much as possible. This will eliminate bulges that distort head contours. Do not measure your head while wearing weaves/wigs/braids. Otherwise, the measurements will not be accurate.
1. The Circumference of the Head:
Measure all around the head. Position tape measure so its edge follows the hair line around the head and nape of the neck. (Average measurement is 22.5 inches).
2. From Forehead to Nape of Neck:
Measure from hairline at center of forehead straight back over crown to center of hairline at nape of neck.
3. Ear to Ear Across Front Hairline:
At front of ear, measure from hairline at base of sideburn, up across the hair line along forehead to same point in front of other ear.
4. From Ear to Ear Over Top of Head:
Measure from hairline directly above the ear across top of head to the hairline directly above the other ear.
5. Point to Point: (From temple to temple)
From temple to temple across the back of head.
6. Nape of Neck:
Measure the width of hairline across the nape of the neck.
