How it is calculated
Each letter covers two consecutive US sizes: XS = 0/2, S = 4/6, M = 8/10, L = 12/14, XL = 16/18, XXL = 20/22, then the chart converts them: UK = US + 4, EU = US + 32, FR = US + 34, IT = US + 38, JP = US + 5.
Example
Inputs: Letter size = M. Result: US size: 8/10; UK size: 12/14; EU size: 40/42.
Limits and caveats
- How letters map to numbers is not an official standard, and some brands call US 0 an XXS.
- Brands differ and can be a full size apart, so check the brand chart before you order.
- Does not include XXS or 3XL and above.
Questions about this tool
What EU size is a medium?
M covers EU 40 and 42 on the common chart, which is US 8 and 10 or UK 12 and 14.
What US size is a large?
L matches US 12 and 14, or EU 44 and 46.
Which of the two numbers should I pick for M?
The lower number suits the smaller end of the band and the higher one the fuller end. Compare your bust and waist with the brand chart to choose.
