Bra size chart: band labels across five systems

Band labels side by side

This chart follows the calculator’s label model: one US/UK band equals one row, and every row names the same band in each system. It translates labels; it does not convert your tape measurement.

Why the numbers differ

US and UK bands use the same numbers. EU bands step in fives, French bands sit fifteen higher than EU, and Australian bands start much lower. These are general label correspondences, not a promise that garments are identical across brands.

A band label is not necessarily your underbust measurement. Brands may round, offset or group measurements, so use the label as a name, not a tape reading.

Using a chart without over-trusting it

Translate the band first, then translate the cup letter separately; cup sequences also differ between systems (see the cup size guide). Use the band and cup labels from the same declared sizing system.

If a brand publishes its own chart, that chart wins over any general table. If your translated size is not sold in a style, that is a limit of the style, not proof your size is wrong.

Next steps

Need a starting size first? Use the calculator with your own measurements. Already have a size and a fit problem? Try the fit check or the sister-size guide before buying a different label.

Find a starting size

If your cups gape or overflow, size and cup shape may both matter. Check your current measurements before changing styles, then compare the estimate with how your bra actually fits.
