International Size Labels & Conversion: Selling Across Regions

Woven size labels with an international size conversion chart

If you sell beyond your home market, size labels and international size conversion matter. A small that fits in the U.S. is a different number in the EU, UK, or Japan. Clear size labeling prevents returns and confusion.

Size label basics

A size label (or size tab) shows the garment size — XS–XXL, a numeric size, or both. It can be a small woven tab, a printed line on the care/content label, or part of a tagless print. Keep it easy to find (neck or waistband) and legible.

International size conversion

Sizing systems differ by region. A rough guide for women’s tops:

US UK EU Letter
4 8 36 XS/S
6 10 38 S
8 12 40 M
10 14 42 M/L
12 16 44 L

Conversions vary by garment and brand — always base labels on your own measured fit. Use this as a starting reference, not an exact rule.

How to label for multiple regions

  • Multi-size labels — print several regional sizes on one label (e.g., “M / US 8 / UK 12 / EU 40”).
  • Region-specific runs — separate size labels per market.
  • Letter sizing — S/M/L travels well and is simplest for many casual garments.
  • Pair with a clear size chart on your website and hang tags.

Tips

  • Base sizes on actual measurements, not just a conversion chart.
  • Keep the size easy to locate — neck or waistband.
  • Order size labels alongside your brand and care labels for consistency.

Frequently asked questions

How do I label clothing sizes for international sales?

Use multi-size labels showing each region’s size, or letter sizing (S/M/L), and back it with a size chart. Base everything on your measured fit.

Is a US medium the same as a EU medium?

Not necessarily — numeric systems differ (US 8 ≈ UK 12 ≈ EU 40 for women’s). Letter sizing is more consistent but still varies by brand.

Can one label show multiple sizes?

Yes — many brands print combined sizes like “M / US 8 / UK 12 / EU 40” on a single label.
