MyBrandSize is a free tool that converts women's clothing sizes between brands — so you can find your size at Zara, H&M, Shein, Uniqlo, Lululemon and more without guessing.
Why it exists
A "medium" or an "EU 38" maps to different body measurements at different brands, and vanity sizing makes label-matching unreliable. We built MyBrandSize to solve that.
How it works
Instead of mapping label to label, MyBrandSize pivots on body measurements: it reads the measurement range a brand assigns to a size, then finds the size in another brand that covers the same range. Enter your measurements once and get your size everywhere.
Our data
Sizes are based on brands' published charts and recognised sizing standards. Some entries may be sample or estimated values until verified; we flag this on brand pages and welcome corrections.
Independent
