Clothing sizes vary by country and have no universal standard. A US women's size 8 is a UK size 12 and an EU size 38. A men's EU suit jacket size 50 corresponds to a US/UK chest of approximately 40 inches. Without a reference, ordering internationally means guessing.
ToolHQ's clothing size converter covers women's and men's sizes across the three major systems, US, UK, and EU, for tops, bottoms, and dresses. Enter your size in any system and get the equivalents instantly.
Key Takeaways

- Men's letter sizes (S, M, L) broadly align across US, UK, and EU with minor fit variations
- EU men's suit and jacket sizes use chest measurement in centimeters (48, 50, 52)
- Sizes are approximate, always check the specific brand's measurement chart
- No data is stored or transmitted, all calculations run locally in your browser
Why clothing sizes differ by country
Clothing sizes are not internationally standardized. The US, UK, and EU each developed their own sizing conventions based on different measurement traditions and body measurement surveys. The result is a system where the same garment number means different things depending on where it was made.
The key rules for women's sizes:
- UK numeric sizes = US numeric sizes + 4 (US 6 = UK 10, US 8 = UK 12, US 10 = UK 14)
- EU numeric sizes are approximately US sizes + 30 (US 6 = EU 36, US 8 = EU 38, US 10 = EU 40)
- Letter sizes (XS, S, M, L, XL) are broadly similar across regions but not identical
The key rules for men's sizes:
- Letter sizes (S, M, L, XL) are roughly equivalent across US, UK, and EU for casual wear
- EU suit and jacket sizes use chest circumference in centimeters (48 = US 38, 50 = US 40, 52 = US 42)
- EU trouser/pants sizes use waist measurement in centimeters (82 = US 32, 86 = US 34, 90 = US 36)

Note: Jeans sizing in the US and UK often uses the waist measurement in inches directly (e.g., W30 L32). EU jeans may use the same inch-based system or a continental system depending on the brand.
Mini-story 1: Maya ordered a dress from a French brand online. She normally wore a US size 10, but the site only listed EU sizes. She entered her US size into ToolHQ's clothing size converter and saw that US 10 corresponds to EU 40. She ordered EU 40 and the dress fit well. She also checked the brand's own measurement chart, which confirmed EU 40 was right for her bust and waist measurements, reinforcing the converter's result.

EU men's suit sizes use chest in centimeters divided by two, approximately. A 50 EU jacket corresponds to a 100cm chest, which is about 39-40 inches. This relationship makes EU suit sizes straightforward to convert once you know the pattern.

Mini-story 2: James was buying a suit jacket as a gift for his brother in Germany. He knew his brother's US chest size was 42 inches. He used ToolHQ's clothing size converter and found that a US/UK 42 corresponds to an EU 52. He found a jacket in EU 52 from a German retailer and the size was correct. He noted for future reference that EU men's suit sizes roughly follow the pattern of doubling the chest-in-inches, then rounding: 42 inches x 2 = 84, which rounds to the nearest EU suit size of 52, a useful mental shortcut.

Frequently asked questions
Why is my US size different from my UK size?
US and UK women's numeric sizes use the same numbers but mean different things. UK sizes are US sizes plus 4. So a US 8 = UK 12, and a US 10 = UK 14. Men's letter sizes (S, M, L) are roughly equivalent, but men's tailored sizes (suits, dress shirts) differ significantly.
Are EU clothing sizes in centimeters?
EU sizes for men's suits and some tailored items are based on chest or waist measurements in centimeters. EU women's numeric sizes (32, 34, 36) are not directly in centimeters, they follow a separate convention where EU 36 corresponds approximately to a 36-inch or 88cm bust.
Can I convert kids' clothing sizes with this tool?
ToolHQ's clothing size converter focuses on adult men's and women's sizes. Children's sizing varies significantly by age, height, and brand, making standardized conversion less reliable.
Why do my sizes vary between brands?
Clothing sizes are not legally standardized internationally. Each brand uses its own fit model and measurement tolerances. A brand that targets a slim fit will size differently from one that targets a regular fit, even if both label the garment the same size.
Is the clothing size converter free?
Yes. ToolHQ's clothing size converter is completely free, with no account, no sign-up, and no usage limits.
The short version
The key rule for women's sizes: UK = US + 4, EU = US + 30 approximately. A US 8 is a UK 12 and an EU 38. For men's casual wear, letter sizes are broadly equivalent across US, UK, and EU. For men's suits, EU sizes use chest measurement in centimeters (EU 50 = US/UK 40). These are conversions, not guarantees, sizing varies by brand, garment construction, and fit model. Always verify with the brand's own measurement chart when ordering internationally. ToolHQ's converter gives you the standard equivalent as a starting point.
