How UK and US bra cup size conversion works above DD
UK sizing uses double letters such as FF, GG and HH. US brands commonly continue through DDD, G, H and I, but some use proprietary sequences. This converter aligns each cup by index rather than assuming identical letters.
How to convert UK band sizes to EU and French bra sizes
A UK 34 band commonly maps to EU 75 and French 90. Australian band labels generally use the UK band minus 22, so UK 34 becomes AU 12. These are label conversions, not new body measurements.
How Comexim and Ewa Michalak bra size conversion differs
Standard EU cup conversion usually follows 2.54 cm steps, while Comexim and some nonstandard EU ranges use 2 cm steps. Ewa Michalak combines metric band labels with UK-style cup letters, and some styles can feel firmer in the band. These specialist results are therefore approximate starting sizes rather than exact brand guarantees.
Why an international bra size converter is still a starting point
Size labels do not standardize cup shape, wire width, stretch or grading between brands. After conversion, check the specific brand chart and compare adjacent sizes when possible.
