Step-by-Step Measuring Guide

1

Position the tape correctly

Wrap the measuring tape around your head at the points where the wig’s edge will sit — usually from your hairline at the forehead, around just above your ears, and down to the nape of your neck.

2

Account for your hair volume

If your natural hair adds bulk (e.g. thick, braided, or curly hair), you may want to add up to 1 inch (about 2.5 cm) to your measurement. Don’t overdo it; too much slack can make the wig loose.

3

Include baby hairs or desired hairline coverage

If you want your wig to cover baby hairs or sit slightly in front of your natural hairline, extend the tape just a bit beyond your hairline to capture that.

4

Record the measurement

Write down the measurement in inches or centimeters. It’s better to round down a bit than up — we can always adjust the cap tighter, but loosening is tougher once it’s fitted.

Final Tips
  • Measure more than once to double-check accuracy.
  • Use a mirror or get help — it’s easy to misread angles.
  • Don’t pull the tape too tight — keep it snug but comfortable.
  • Keep your hair in the style you’ll wear under the wig (braids, curls, etc.) when measuring.
