Measure a wig cap before choosing a size

Arrange your own hair as you will wear it beneath the wig. Using a soft tape, record the circumference around the intended hairline, the front-to-back distance over the head and the ear-to-ear distance over the crown. Follow the maker’s diagram for the measuring points: instructions may differ between brands. Repeat each measurement without pulling the tape tight.

Send all three figures and the units to the supplier. Ask which model and cap size they recommend and how much adjustment its straps actually offer. Do not assume that a larger adjustment range compensates for a cap that is too shallow or too short from front to back.

At a permitted fitting, check the position of the front edge, ear tabs and nape. Move your head gently and look for slipping or uncomfortable pressure. More tension is not automatically a better fit. Stop wearing an uncomfortable item rather than tightening it further.

Keep the measurements and the supplier’s written advice with your order. Do not cut lace or make irreversible alterations until fit and return conditions are clear.
