The Difference Between European T-Shirt Sizes And Asian T-Shirt Sizes

Buying a T-shirt sounds simple—until you shop across borders. A size “M” in one market can fit like a “S” or even an “L” in another. This happens because European and Asian sizing use different body standards and shirt cuts. In this guide, you’ll learn the key differences between these systems, how to read Asian codes like 160/84A, and how to use real body measurements to choose the right fit with confidence.

• Letter Sizes: XS, S, M, L, XL (Common in Europe and Global brands).
• Number Systems: Height-based codes (Asia) or specific regional numbers (US 0-16, UK 4-20, IT 36-52).

Why European Sizes Often Feel Larger

When people say “European size runs large,” they are referring to the cut. European-fit T-shirts are typically designed to be wider and longer to accommodate larger average body frames. In contrast, Asian-fit T-shirts are often slimmer and shorter.

• European Cut: Roomy, relaxed, and longer hemline.
• Asian Cut: More fitted, narrower shoulders, and shorter length.

Even if the label shows the same letter (like “M”), a European shirt will generally feel much roomier than an Asian one.

Reading Asian Size Codes (e.g., 160/84A)

In many Asian markets, sizes are written based on data rather than just letters. A code like 160/84A provides specific measurements in centimeters:

• 160: Recommended height (cm).
• 84: Bust measurement (cm).
• A: Standard body type (B or C indicate wider builds).

The Best Way to Choose: Real Body Measurements

Letter sizes change by brand, but centimeters do not. For the perfect T-shirt fit, always use a tape measure and prioritize your bust measurement. If you are between sizes, choose the larger one for comfort, or go up one full size for an oversized street-style look.

Production Note for Custom Orders

For custom manufacturing, we advise against following a single “standard.” Instead, collect key body data from your target market and adjust your Tech Pack patterns accordingly. At Mekong Garment, we specialize in adjusting patterns to match either European or Asian fit standards, ensuring your collection fits your customers perfectly from the first sample.

Conclusion

European and Asian T-shirt sizes may look the same on the tag, but the fit in real life is vastly different. Don’t rely on letters alone—use body measurements and clear size charts to guide your choices. For brands, successful production starts with clear data and a confirmed target market standard. This simple step saves time, costs, and prevents the frustration of poor-fitting garments.
