How to Measure Human Hair Bundles

Measure straight human hair from the weft to the hair ends. For Body Wave, Deep Wave, Water Wave, Loose Wave, Curly, and other textured hair, gently stretch the hair straight before measuring.

Straight Hair Length Display

Straight hair usually shows more visible length than wavy or curly textures because it falls directly downward. Use this chart to compare common straight human hair lengths from 10 inches to 30 inches.

Wavy Hair Length Display

Wavy hair can look shorter than straight hair at the same listed length because of the wave pattern and volume. Hair length is measured when the textured hair is gently stretched straight.

Hair Length & Wig Size FAQs

How is human hair length measured?

Human hair bundles are measured from the weft to the ends. Wavy and curly textures should be gently stretched straight before measuring.

Does wavy hair look shorter than straight hair?

Yes. Wavy hair can look shorter than straight hair at the same listed length because the wave pattern reduces the visible vertical length.

How do I measure an HD lace closure or frontal?

Measure from the lace base to the hair ends in a straight line. Stretch wavy or curly hair straight before measuring.

How do I choose a wig cap size?

Measure your head circumference around the natural hairline and compare it with the applicable cap size chart. If you are unsure, contact JAZZWIGS before ordering.
