The Included Bra Size Standards
The calculator will allow you to convert between the bra sizes for Europe (International), UK, US, Australia, France and Italy.
Each of these bra standards differs from the others in at least one of the two measurements (band size or cup size). For instance; while France follows the same European standard for cup sizes, their band sizes are always 15 cm larger.
In case you wonder where in the world each standard is used, here is a summary:
| Bra Size System | Countries |
|---|---|
| Europe (International) | Most European countries and large parts of the world including Japan |
| UK | UK and Portugal |
| US | US |
| France | France, Belgium, Spain |
| Australia | Australia and New Zealand |
| Italy | Italy |
