What this tool does
The International Clothing Size Converter helps you find your correct clothing size when shopping from international brands or retailers. It converts between US, UK, EU, Australian, Japanese, Italian, and French sizing systems for tops, bottoms, shoes, dresses, and bras — for men, women, and children.
Whether you are ordering from a European fashion site, shopping a Japanese brand, or buying clothes as a gift for someone in another country, this tool gives you the equivalent size instantly. No math needed.
All conversions are based on standard international sizing references and cover the most common size ranges. Because sizing varies by brand and garment fit, this tool is best used as a starting reference alongside individual retailer size charts.
How to use
1. Select your gender: Women, Men, or Children. 2. Choose the clothing type: Tops, Bottoms, Shoes, Dresses, or Bras. 3. Pick the region where you already know your size (for example, US). 4. Select your size from the dropdown. 5. Your equivalent sizes in all other regions appear instantly below.
Results update as you change any selection — no button to press.
Understanding clothing size systems
Clothing sizes are not standardized globally, which creates confusion when shopping internationally. Here is a breakdown of the major systems:
**US Sizes** Women's US sizes typically run as numeric sizes (2, 4, 6...) for dresses and tops, and as waist measurements in inches for pants. Men's sizes use labels (S, M, L, XL) or numeric waist/inseam measurements.
**UK Sizes** Women's UK sizes run 4 numbers higher than US sizes — a US 8 is a UK 12, for example. Men's UK sizes generally match US labels (S, M, L), though some measurements differ.
**EU Sizes** European sizes use a higher numeric system, often 30-60 for clothing. EU shoe sizes are larger numbers than US or UK. EU sizes are widely used across continental Europe including German, Spanish, and Portuguese retailers.
**Japanese Sizes** Japan uses a unique sizing system. Women's clothing often uses numbers 5-19, while men use S/M/L labels with Japanese-specific measurements. Shoe sizes in Japan are expressed in centimeters of foot length.
**Italian and French Sizes** Italy and France each have their own numeric systems that differ from standard EU sizing. Italian and French sizes tend to run smaller than equivalent US sizes.
**Australian Sizes** Australian women's clothing sizes typically run 2 sizes lower than US (a US 8 = AU 12). Shoe sizes in Australia differ from both US and UK.
FAQs
Q: Why does my EU size differ between brands? A: EU sizes are a reference standard, not a mandatory specification. Individual brands may size up or down based on their target market, fit philosophy, or production region. Always check the brand's own size chart when possible.
Q: Are US and Canadian clothing sizes the same? A: Yes, Canadian clothing sizes use the same numbering system as US sizes. You can use US size conversions for Canadian retailers without adjustment.
Q: What does "JP (cm)" mean for shoe sizes? A: Japanese shoe sizes are expressed in centimeters of foot length rather than a numeric size code. A US women's size 7 corresponds to approximately 24 cm in Japanese sizing. Measure your foot from heel to toe to find your JP shoe size.
Q: Do children's sizes work differently internationally? A: Yes. Children's sizes often use age ranges (such as 3-4Y) or height in centimeters (such as EU 98-104) rather than simple numeric codes. The converter uses common reference sizes, but fit will vary significantly with the child's actual measurements.
Q: Why are bra sizes listed separately? A: Bra sizing uses a combination of band size (a number) and cup size (a letter), and the band measurement system differs between regions. For example, a US/UK 34B becomes an EU 75B and a French 90B because each country adds a different offset to the underbust measurement in centimeters.
Q: I wear a US Large but my EU size shows 48-50. Which should I order? A: For men's EU tops, sizes 48-50 represent a Medium-to-Large range. If a brand only offers one number, ordering 48 is generally the safer choice for a standard Medium fit, while 50 fits closer to a large US fit. Check the brand's chest measurement chart to be certain.
Q: Can I use this tool for athletic or sportswear? A: The conversions work as a starting point for athletic wear, but sportswear brands often use brand-specific sizing that may differ from standard international tables. Many sporting goods brands publish their own size guides that account for stretch, compression, or activity-specific fit.
Q: Are shoe sizes the same for all shoe types? A: Generally yes within a country, but slight differences can exist between athletic shoes, dress shoes, and boots. Width is also an important factor not captured by size numbers alone. Use this converter for a starting point, then consult retailer fit guides for narrow or wide width needs.
