About this app

My Size instantly converts shoe, clothing, pants, hat, ring, kids, and bra sizes between Korean, US, EU, UK, and Japanese standards — ideal for online shopping, overseas travel, or buying international brands.

Size Converter — 9 Categories
My Size covers shoes (foot length in mm), men's tops, women's tops, men's pants (inch/cm), women's pants, hats, rings, kids clothing, and bras. Compare size charts across Korean, US (American), European (EU), UK, and Japanese size systems in one tap.

13 Shoe Brand Guides
Nike, Adidas, New Balance, Converse, Vans, ASICS, On Running, Hoka, Salomon, Brooks, Saucony, Mizuno, and Puma — each with a width tendency rating (narrow / true to size / wide) and practical fit tips. For example, Nike runs narrow, so sizing up is often recommended — the kind of real-world guidance this app provides.

5 Clothing Brand Guides
Zara, H&M, Uniqlo, Gap, and Levi's — with brand-specific sizing notes and shopping tips to help you make the right choice.
