9 EU and FR/BE cup letters, one page each
The letters this system writes, each with its own page.
EU band labels run from 60 to 140, rising by 5 for each 2 in the US and UK band. The EU method rounds your underbust to the nearest 5 cm. A band label identifies the number on a tag, not a body measurement. French and Belgian bands add 15 to the EU label, running from 75 to 155. On tags, the French and Belgian cup letters are the same as EU letters.
EU cup letters run in this order: AA, A, B, C, D, E, F, G, H, I, J, K, L, M, N, O. The EU method counts cup letters in centimetres, beginning with AA at 10 cm and continuing to H. Published inch charts list EU letters from AA to O for differences from less than 1 in to 15 in; other differences are not listed. Difference means your bust minus the band.
Published charts disagree on the cup scale: the EU method defines letters in centimetres, while inch charts assign EU letters to differences in inches, and the scales do not line up. French and Belgian cup letters match the EU letters. Example EU tags include 70A, 75B and 80C.
