Formula
How the calculation works
The calculator takes the size you enter and the system it belongs to and first converts it to a UK size as the base.
It then adds one to get the US size and thirty-three to get the EU size, while the Bangladeshi figure stays equal to UK.
All four values are shown together so you can check the mapping against the shoes you already own.
Common mistakes
- Assuming the same number means the same fit across systems, since a UK 8 is not a US 8 or an EU 8.
- Ignoring that children's and women's sizes follow different offsets from the men's scale used here.
When to use it
- Online shoppers use it to pick the right size when a foreign store lists shoes in a different numbering system.
- Travellers and expatriates use it to compare their usual size with the sizes printed on shoes sold abroad.
Worked example
A UK size 8 converts to US 9, EU 41 and Bangladesh 8.
Common questions
Is this conversion exact?
It is a close approximation for adult sizes, so always check the brand chart, because last shapes and widths vary between makers.
