Sizes vary between brands — often by a whole size. If the shop has its own size chart in centimetres, compare it with your measurements. That beats any conversion table, this one included.

How to use it
Pick women’s or men’s and the size you know to see the matching US, UK, EU, and letter sizes, plus the body measurements that size is meant for.
Buying clothes from another country? Pick the type of clothing and the size you normally wear, and see the matching US, UK, EU, and S/M/L sizes.
Quick rules for women’s sizes: UK is 4 higher than US (US 8 = UK 12), and EU is about 30 higher (US 8 = EU 38). Men’s sizes are simpler — the chest in inches in the US and UK, and in centimetres in Europe.
Here’s the catch: clothing sizes aren’t official anywhere, and brands vary a lot. Your body measurements are the one thing that doesn’t change, so they’re shown with every size. You can even start from your measurements instead.
Buying vintage? Sizes have shrunk over the years — a size 8 today is roughly a size 12 from the 1980s — so ask for measurements.
Women’s sizes: US, UK, EU
UK is US plus 4, and EU is US plus 30, for most sizes. The bust measurement is what each size is meant to fit.
| US / UK / EU | Bust |
|---|---|
| 2 / 6 / 32 | 82 cm |
| 4 / 8 / 34 | 86 cm |
| 6 / 10 / 36 | 90 cm |
| 8 / 12 / 38 | 94 cm |
| 10 / 14 / 40 | 98 cm |
| 12 / 16 / 42 | 103 cm |
| 14 / 18 / 44 | 108 cm |
| 16 / 20 / 46 | 113 cm |
Men’s tops and jackets
Men’s sizes are the chest measurement — in inches in the US and UK, and centimetres in Europe. So the EU size is roughly the US size plus 10.
| US / UK / EU | Chest |
|---|---|
| 34 / 34 / 44 | 87 cm |
| 36 / 36 / 46 | 92 cm |
| 38 / 38 / 48 | 97 cm |
| 40 / 40 / 50 | 102 cm |
| 42 / 42 / 52 | 107 cm |
| 44 / 44 / 54 | 112 cm |
| 46 / 46 / 56 | 117 cm |
Letter sizes
Each letter size usually covers two number sizes, so it fits less precisely. If a shop offers both, go by the number.
| Letter | US women’s / US men’s |
|---|---|
| XS | 2 / 32–34 |
| S | 4–6 / 34–36 |
| M | 8–10 / 38–40 |
| L | 12–14 / 42–44 |
| XL | 16–18 / 46 |
| XXL | 20 / 48 |
FAQ
What is a UK size 12 in US sizes?
A US 8. UK women’s sizes are usually 4 higher than US.
What is a US size 8 in EU sizes?
An EU 38 for women’s tops and dresses. Some European brands differ by one size, so check the bust measurement too.
How do I measure myself?
Measure your bust at the fullest point, your waist at the narrowest, and your hips about 20 cm below your waist. Keep the tape level and snug, not tight. For men: chest under the arms, and waist where your trousers sit.
Why do sizes differ so much between brands?
Clothing sizes aren’t standardised anywhere. If a shop has a size chart in centimetres, compare it with your measurements.
Are vintage sizes different?
Yes — about two sizes smaller. A vintage 12 is roughly a modern 8, so buy by measurement.
How it worksFor the curious
US women’s sizing has no legal or industry definition; the voluntary US standard was withdrawn in 1983 and not replaced. Country-to-country tables are therefore published conventions, not facts about garments.
Vanity sizing has shifted labels about two sizes smaller since the 1980s. The standard offsets — US + 4 = UK, US + 30 = EU for women’s tops and dresses — hold across most of the range, with some European brands numbering one step differently.
Men’s sizing is a measurement: chest and waist in inches in the US and UK, centimetres in Europe, so the EU number is roughly the US number plus 10. That makes men’s conversions more reliable than women’s.
