A lace front wig listing throws three choices at you at once: lace size, length, and density. Each one changes how the wig looks and what it costs. Here is what they mean in plain terms, using our pink human hair lace front wig as the example.
Lace size, 13x4 or 13x6
The numbers are inches of lace across the front. A 13x4 gives you a parting strip that runs ear to ear and 4 inches back. A 13x6 gives you 6 inches back, so you can part deeper and pull the front up with a more natural hairline. If you wear a simple middle or side part, 13x4 is enough. If you change your part often, pick 13x6.
Length, 12 to 40 inches
Length is measured stretched straight. 12 to 16 inches sits at the shoulders. 18 to 24 inches is the most worn range and reaches the chest to mid back. 26 inches and up is full drama length and costs more, because it is more hair. When in doubt, measure from the crown down your back with a tape and match the number.
Density, 150% or 180%
Density is how much hair is on the cap. 150% looks like a natural full head of hair and feels lighter. 180% is noticeably thicker and reads glam. Both densities on this wig ship from the United States.
