How it is calculated

Band: US and UK 32 = EU 70 = FR 85 = IT 1 = AU 10, and each step adds 2 in (US, UK), 5 cm (EU, FR), 1 (IT) or 2 (AU). Cup: letters are matched by position. UK: AA A B C D DD E F FF G, US: AA A B C D DD DDD G H I, EU, FR and IT: AA A B C D E F G H I.

Example

Inputs: EU band = 75, EU cup = E. Result: US size: 34DD; UK size: 34DD; French size: 90E.

Limits and caveats

  • Follows the usual retail chart; some brands differ by one cup size.
  • Some US brands label DDD as F, and Australian cup letters past F are not consistent, so they are not shown.
