My Own Cap Size Catastrophe
You’d think after my dog, Buster, ate my favorite toupee, I’d be more careful. But no. My next wig was a beautiful, expensive piece that I ordered online without checking the cap size. It was a ‘large,’ and I have an average-sized head. I looked like a squirrel storing nuts under a hat. So let me save you from that embarrassment.
What Are Wig Cap Sizes?
Wig cap sizes refer to the circumference of the wig’s base, measured in inches or centimeters. The most common sizes are Small, Average, Large, and Petite. Some brands also offer Extra Small or Extra Large. The size affects not only how the wig fits but also how natural it looks.
- Petite/Small: 20.5–21.5 inches (52–54.5 cm)
- Average: 21.5–22.5 inches (54.5–57 cm)
- Large: 22.5–23.5 inches (57–59.5 cm)
- Extra Large: 23.5+ inches (59.5+ cm)
These measurements are for the circumference. But cap sizes also account for the front-to-back and ear-to-ear distances, plus the nape (back of neck) area. Some wigs have adjustable straps or ear tabs to fine-tune the fit.
How to Measure Your Head for a Wig
Grab a soft measuring tape. Measure around your head where a wig would sit: start at your hairline (forehead), go above your ears, and around the nape of your neck. That’s your circumference. Then measure from your hairline to the nape (front-to-back) and from ear to ear over the top of your head. Compare these to the brand’s sizing chart.
- Circumference: around head at hairline level
- Front to Nape: from hairline to base of skull
- Ear to Ear: over the top, from one ear to the other
Don’t pull the tape too tight—you want a snug but comfortable fit. Write down the numbers. If you’re between sizes, go with the larger size and use adjusters. Trust me, a too-small wig will give you a headache faster than Buster stealing your breakfast.
Why Cap Size Matters
The right cap size ensures the wig stays put, looks natural, and feels comfortable. A too-large cap will slip and look bulky; a too-small cap will pinch and show telltale bulges. Plus, proper fit means fewer adjustments and more confidence. Whether you’re wearing a wig for hair loss, fashion, or cosplay, size is key.
Final Tips from a Cap-Size Veteran
Don’t rely on hat size or your partner’s guess. Measure your head properly. If you’re still unsure, many brands offer adjustable caps or custom sizing. And keep Buster away from your measuring tape—I’m still finding bits of mine in the backyard.
