US does not have a separately published cup-letter scale in the sources checked for this site, so only the band conversion is shown above. For cup letters across US, UK and EU, see the cup size chart.

Bra size is two independent measurements folded into one label: the band comes from the underbust circumference, and the cup comes from the difference between the bust and the band. France and US both describe the same body, just with different numbering, so the band and cup charts above convert the label without changing the fit.

Band and cup conversions here are checked against the internationally published bra size conversion tables (matching the reference tables in Wikipedia's "Brassiere measurement" article), including Italy's separate small-number band scale. There is no single global standard for bra sizing the way there is for shoes or rings, so treat the chart as a strong starting point and confirm fit in person where possible.

To measure your own band and bust, see how to measure bra size, or use the bra size calculator to get your size from measurements directly.

Common questions

What is a France 90 band in US?

A France 90 band is a US 34 band, both fitting an underbust measurement of about 73 to 77 cm.

Does this chart convert cup letters to US?

No. There is no separately published cup-letter scale for US in the sources checked, so this page compares band size only. For cup letters across US, UK and EU, see the full cup size chart.

How do I convert a France bra size to US?

Find your France band in the chart and read across to the US column for the band, then do the same on the cup table if it is shown. Both are anchored to real body measurements, so the conversion holds regardless of brand.

What if I'm between two band sizes?

Choose the smaller band on the loosest hook. A band that is snug on the loosest setting still has room to tighten as the band stretches with wash and wear.
