What If You're Between Wig Sizes?

If your measurements are between two cap sizes, it is always advisable to go for the larger cap size. Many of the wigs nowadays have adjustable straps or tabs to tighten the wig, which makes it a comfortable and good fit for your head. It is always better to select a slightly bigger cap than one that is too small and to be tight, fitting irritated and even cause a lot of irritation during long hours. If you’re unsure about the wig size between sizes, it’s always a good idea to compare your measurements with our wig sizing chart and take into account your hair volume, as hair that’s thicker or more voluminous than average may affect your wig size, having a larger crown diameter inside the cap.
For the most precise fit, get a good grip of your head’s measurement and utilize our measurement guide.
