Find Your Wig Cap Size

While average size wigs tend to fit about 95% of customers, you will find that quite a few wigs also come in petite and large sizes. Consider that many also have adjustable straps that give up to 1/2” so that you can achieve a comfortable and secure fit. To determine the right size wig for you, measure the circumference of your head from the front hairline, behind your ear, to the nape of your neck, to your other ear and then back to the front hairline. Jot down your measurement then consult the table below. Please note that sizes may vary slightly by brand and that not all wigs are available in all cap sizes.
