Clothing Size Converter
Convert clothing sizes between US, UK, EU, Japan, and Australia. Free, accurate international size charts for all clothing types.
Important: These conversions are approximations based on standard size charts. Actual sizing varies significantly between brands. For the most accurate fit, measure your body and compare to brand-specific measurements.
Understanding International Clothing Sizes
Clothing sizes vary significantly across countries, making international shopping confusing. A US size 8 is approximately a UK size 12, an EU size 38, and a Japan size 11. These differences stem from different measurement systems and body proportion standards used in each country.
Our free clothing size converter helps you translate between sizing systems, but remember that clothing sizes aren't standardized even within the same country. Brands create their own size charts, and vanity sizing means a size 8 at one brand might fit like a size 12 at another.
For the most accurate fit, we recommend taking your body measurements and comparing them to brand-specific size charts. Better yet, use AI body scanning technology to get precise measurements that work across all brands.

Frequently Asked Questions
How accurate are international size conversions?
Our size converter uses standardized international sizing charts, but keep in mind that sizes can vary between brands. These conversions are approximations based on industry standards. For the most accurate fit, we recommend using your body measurements and comparing them to brand-specific size charts, or using our AI body scanning tool.
Why do clothing sizes differ between countries?
Different countries developed their own sizing systems based on local population measurements and standards. The US, UK, EU, and Japan all use different numbering systems. Additionally, there's no universal standard within countries—brands can create their own size charts, leading to further inconsistency.
How do I convert US size to UK size?
For women's clothing, UK sizes are typically 4 sizes larger than US sizes (US 8 = UK 12). For men's clothing, US and UK sizes are usually the same for tops, but pants use different systems (US 32 waist = UK 32 waist, but the rise and length may differ). Use our converter above for specific conversions.
What's the difference between EU and US sizes?
EU sizes are typically 30 numbers higher than US sizes for women's clothing (US 8 = EU 38). For men's tops, EU sizes are about 10 numbers higher (US 40 = EU 50). EU shoe sizes use a completely different numbering system based on foot length in centimeters.
Should I trust size converters or measure my body?
Both are useful, but body measurements are more reliable. Size converters help you understand international sizing systems, but actual fit depends on your specific body measurements and how brands cut their clothes. For the best results, take accurate body measurements and compare them to garment specifications. Our AI body scanning tool can help you get precise measurements.
