How long are 20 inch hair extensions?

Use this 12–24 inch hair extension chart as a visual reference for where 20 inch extensions may fall. Measurements run from the attachment point to the ends, and the position shown assumes straight hair.

This is a length reference, not an inventory list. Final placement varies with the client’s height, body proportions and installation position; waves and curls can appear shorter than the same measured length worn straight.
