Asian Size to US Size Conversion Overview

Inconvenient as it may be, not every country measures clothing sizes in the same way. Asian clothing manufacturers use a different system than US ones, which use different sizes than Europe, and so on.

If your store sells clothing that’s made in another country, you’ll likely have to convert the sizes to your own country’s. Having accurate size conversion info is also critical when ordering stock from Asian suppliers.

As a general rule, Asian clothing runs smaller than US or European clothing. So for example, when comparing Asian sizes to US sizes, an Asian large may be a US size small, which in turn may be a European size medium. The size conversion depends on a couple of different factors which we’ll cover below.

4 Tips for Converting Asian Size to US in Your eCommerce Store

Ok, hopefully those charts help you understand the different sizes across different continents and markets. With those covered, here are a few tips to help your or your customers understand size conversions. Remember, the less doubt your customers have, the more sales you’ll get on your checkout pages.

1. Make the Sizing System Super Clear on The Product Page

If your store sells products to multiple countries, consider using a different version of each product page depending on where a user is from. If that’s not possible, you’ll need to make it super clear to customers which system you’re using. Each product page and option should include whether you’re using US, EU, or Asian sizes as the default.

2. Make Your Size Charts Easy to Find & Read

For stores that have multiple size systems, make your charts easy to find from each product page. The less hassle it is to figure out the right size, the more of your customers that will make it to the checkout.

3. Contact Suppliers or Visit Their Websites

The best way to find out product sizes is by contacting the suppliers themselves. Most of the time a supplier will include their sizing chart on-site. From there, you’ll have to convert each size for your own store.

4. Test Order Your Own Products

You should also test out each product before you start selling. It’s always best practice to order samples of the product to get a hands-on view if the sizes are accurate. In addition, ordering a product helps you judge the quality too. What’s more is that you can then take custom photos of the product for use on your product pages and in your marketing collateral.
