The Conversion Rules

  • For Bands: EU bands are the underbust measurement in centimetres. To estimate your EU band from a UK band, add 5 (e.g. UK 34 + 5 = EU 75 approx). However, the exact conversion requires the chart above.
  • For Cups: Up to a D cup, UK and EU letters are identical (A, B, C, D). After D, the UK uses double letters (DD, FF) whereas Europe continues with single letters (E, F, G).
  • French Sizing: French (FR) bands are exactly 15 higher than European bands. So an EU 75 is an FR 90. The cups remain the same as EU cups.

Frequently Asked Questions

An EU 75B is equivalent to a UK 34B. The cup size is exactly the same, but the band 75cm translates to a 34-inch band in the UK.

Do all European brands use the same sizing?+

Mostly yes. Countries like Germany, Poland, and the Netherlands use standard EU sizing. However, France and Italy use different band numbering systems, though their cup letters usually follow the EU standard.
