How to use Clothing Size Converter

  1. Choose the category — Men's Tops or Women's Tops / Dresses — in the first dropdown.
  2. Select the size you know (XS to XXL) in the second dropdown.
  3. Read the equivalents shown on the cards: International, US, UK and EU versions of that size.
  4. Verify with the brand's own chart when it is available — regional charts get you close; the brand's cm measurements confirm it.

What is Clothing Size Converter?

A clothing size converter maps garment sizes between regional systems — the international letter sizes (XS–XXL), US numeric sizes, UK sizes and EU sizes. The systems disagree more than people expect: a women's US 8 is a UK 12 and an EU 40, while men's sizing usually tracks chest measurement in inches (US/UK) versus centimeters-based EU numbers around 44–62.

Letter sizes are the loosest layer of all — one brand's M is another's L — but the numeric US/UK/EU ladders keep fixed offsets from each other, which is what this converter encodes: UK = US + 4 for women's sizes, and EU ≈ US + 32 for women's, EU ≈ chest-inches converted to a 44–62 scale for men's tops.

About the Clothing Size Converter

This converter covers men's tops and women's tops/dresses across four systems — International letters (XS to XXL), US, UK and EU — showing all equivalents for any size you pick.

It removes the guesswork of international shopping: a men's M is US/UK 38–40 and EU 48–50; a women's M is US 8–10, UK 12–14, EU 40–42. Order from a European store using your US size unconverted and you will typically receive a garment two sizes small — the most common cross-border sizing mistake.

Because brands cut differently (fast fashion runs small, outdoor brands run large), treat the chart as the correct starting point, then confirm against the specific brand's measurement table — especially chest width in cm for tops.

Frequently Asked Questions

A women's US 8 is a UK 12 and an EU 40 — part of the fixed offsets: UK = US + 4, EU = US + 32 for women's clothing.
Men's S is US/UK 34–36 (EU 44–46), M is 38–40 (EU 48–50), L is 42–44 (EU 52–54), XL is 46–48 (EU 56–58). The US/UK numbers correspond to chest size in inches.
Most likely an unconverted size: an EU 40 is a women's US 8, not a US 40-anything, and a men's EU 50 is a US M/39 — using your US number as an EU number lands about two sizes off.
Only roughly. Letter sizes have no legal definition, and vanity sizing shifts them over time. The numeric US/UK/EU ladders are more stable, and the brand's own cm chart is the ground truth.
Chest circumference at the widest point (and hips for dresses), in cm, with a relaxed posture. Compare that number to the brand's size chart rather than converting a size from memory.
