[How to Read Overseas Wig Sizes] Inch-to-cm Conversion Chart and a Guide to Choosing the Right Size

Have you ever been confused when buying a wig from an overseas store, wondering things like “I don’t understand the size in inches” or “Where exactly do I measure my head circumference?”
Because wig sizing standards and units differ between Japan and overseas markets, getting it wrong can lead to problems like “it doesn’t fit” or “it’s shorter than I expected.”

In this article, we’ll clearly explain how to read overseas wig sizes, provide an inch-to-cm conversion chart, and show you how to choose the right size for yourself.

The Basics of Overseas Wig Size Labels

On overseas shopping sites, it is common for hair length and head circumference (cap size) to be listed in inches.

• 1 inch = about 2.54 centimeters

How to Read Hair Length (Length)

A wig’s listed length refers to the longest part of the hair from root to tip.
Because of that, curled or wavy styles may look a little shorter in practice.

Example:

26 inch Long Straight Wig
This means a long straight wig of about 66 cm.

Head Circumference Size

For overseas wigs, the cap size (the inner net) may also be shown in inches.
This refers to your head circumference, or the measurement around your head.

Many Japanese women fall around 21.5 to 22.5 inches (about 54 to 57 cm)

If you’re choosing an overseas wig, around 22 inches is often the easiest fit.
Personally, mine is around 61 cm, so finding larger sizes can be quite difficult.

Let’s Decode a Real Label Example

When you see a product description like the one below, here’s how to interpret it.

In other words, it’s a standard-size long wig made of heat-resistant fiber.
