Understanding Hair Extension Lengths

Hair extension lengths are measured from the top of the weft or clip to the ends of the strands, typically in inches. This measurement determines where the hair will fall on your body, but things like your height, natural hair texture, and body shape can affect how it looks. Straight hair extensions usually hang true to their listed length, while wavy or curly ones might appear shorter because of the way the curls coil up. For example, an 18 inch curly hair length might look closer to 16 inches when left natural. To get a clear picture, stretch the strands fully when measuring.

Most brands offer a hair extension length guide to help visualize how different lengths will look, but nothing beats holding a measuring tape against your back to see where the extensions will fall. It’s a simple way to make sure your choice feels just right.
