A comfortable wig fit starts with accurate measurements. Because cap construction and adjustability vary by product, use this guide as a measuring reference and confirm the fit information on the individual product page before ordering.
How to measure your head circumference
Use a soft measuring tape. Start at the front hairline, guide the tape around the head above the ears and across the nape, then return to the starting point. Keep the tape snug without pulling it tight. Measure twice for consistency.
Common wig-cap size references
- Small: approximately 21–21.5 inches (53–54.5 cm)
- Medium: approximately 22–22.5 inches (56–57 cm)
- Large: approximately 23–23.5 inches (58.5–59.5 cm)
These are general industry reference ranges, not a guarantee that every Melted Hair product is offered in these exact cap sizes. Adjustable straps, bands, combs, drawstrings, and other cap features vary by style.
Understanding density
Density describes how full a wig is intended to look; it is separate from cap size. A higher percentage generally indicates more fullness, but available density options differ by product and sometimes by variant. Use the options shown on the product page as the source for what is currently available.
Understanding lace size
Numbers such as 4x4, 5x5, 13x4, and 13x6 refer to the approximate dimensions of the lace area. A larger lace area can provide more room for parting, while a smaller closure uses a more limited lace area. A 360-lace construction uses lace around the perimeter. Exact construction and styling flexibility can still vary by product.
