European Bra Sizes
European bra sizes give the band in centimetres in steps of 5. On size charts, EU 70 = US/UK 32, 75 = 34, 80 = 36 and 85 = 38. So 75C is a 34C and 80B is a 36B. Cups match up to D; EU E equals UK DD, and French sizes add 15 to the band.

Converted size
Brands do not all follow the same chart. Treat converted sizes as a starting point and check the brand’s own size guide.

How European sizes are measured
European sizes give the band in centimetres. Some European size guides measure in centimetres with their own steps, which can give a different result than converting a UK or US size. This site works out your size with the inch method and converts it, so all systems agree. If a European brand publishes its own measuring guide, use it for that brand.
French, Spanish and Belgian labels
French sizes use EU cup letters with bands 15 higher, so EU 75B is French 90B. Some Spanish and Belgian brands also use French numbers, and some Italian brands use their own numbering, so check the brand’s chart.
Frequently asked questions
What is 75C in US size?
On standard size charts a 75C converts to a US and UK 34C, a French 90C and an Australian 12C. Brands vary, so try the size or check the brand’s own chart.
What is 80B in US size?
An EU 80B converts to a US and UK 36B, a French 95B and an Australian 14B on standard charts. If the band feels too loose, the sister size 75C has about the same cup volume.
What is 70A in US size?
An EU 70A is a US and UK 32A, a French 85A and an Australian 10A on standard size charts. Its sister sizes are 65B and 75AA.
What is the European equivalent of a UK DD?
A UK DD is an E in EU and French sizing. So a UK 34DD is an EU 75E and a French 90E. A UK E is an EU F.
Why do EU and French sizes differ?
They share cup letters but French bands are 15 higher. EU 80C and French 95C are the same size. Some Spanish and Belgian labels use the French numbers.
Why does a European brand chart give me another size?
Some brands measure in centimetres with their own steps or size their bands differently. The two results are often one or two sister sizes apart. Use the brand’s chart for that brand and try the size that feels right.
