What Size Am I on AliExpress?

AliExpress sizing is the most confusing of all Asian retailers because sizes run the smallest and vary the most between sellers. Your AliExpress size is typically two or more sizes larger than your US size — a US Medium often needs a 2XL or even 3XL on AliExpress. This dramatic difference catches many first-time buyers off guard. The best approach is to forget about letter sizes entirely and focus on the centimetre measurements that most AliExpress sellers provide. Our converter gives you the right starting size for AliExpress across tops, jeans, shoes and swimwear. Use it as your first step, then verify against the specific product's measurement chart. With experience, you'll develop an instinct for AliExpress sizing, but every category requires its own conversion.
