Our lengths are true: every strand measures the full stated length from the point where it's sewn into the cap. Hair is sewn in all over the cap, from the crown down to the nape, so the strands end at different points — that's what gives the wig its natural layers. That is why a wig always falls longer than its number: on an 18-inch wig, measured from the top of the head, the shortest layers fall at about 18 inches and the longest can reach about 24 inches.
