About Fashion Size Converter
Fashion Size Converter is a free, browser-based tool that converts shoe, clothing, and ring sizes between Korean (KR), US, UK, and EU standards. It runs entirely in your browser, so nothing you enter is sent to a server.
The tool covers three size types in one place: shoes, clothing (tops and bottoms), and rings. It is built for international online shopping, where the same garment or shoe can carry very different size labels depending on the region.
For shoes, enter a foot length in millimeters or centimeters, or a regional size such as EU, US Men, US Women, or UK, and the matching values are calculated instantly. Clothing and ring sizes use built-in equivalence tables, so you can tap any value to see the corresponding S/M/L, US, KR, EU, UK, or ring diameter in millimeters.
Results are approximate and meant for reference. Shoe conversions follow ISO 19407 formulas, and clothing and ring charts are general guidelines, so actual fit still varies by brand. Check the specific brand size chart before you buy.
Frequently asked questions
- How do I convert my Korean shoe size to US or EU?
- Open the Shoe Sizes tab, enter your foot length in millimeters (the Korean and Japanese standard), and the tool shows the equivalent EU, US Men, US Women, and UK sizes at once.
- Are the converted sizes exact?
- No. They are approximate values based on ISO 19407 formulas and common size charts. Brand sizing differs, so always confirm against the seller's own size chart.
- Is my data sent anywhere?
- No. All conversions are calculated in your browser using built-in formulas and tables, so the measurements and sizes you enter never leave your device.
