Bra Size Calculator Brazil
Brazil uses centimetre bands like the EU system: 70, 75, 80, 85, 90, 95 with consecutive cup letters. Some Brazilian brands also print an alternate 40/42-style numbering — this page explains both.

Sizes on this page are estimates. Sizing varies by brand and style, so always check the brand’s own size chart and try on before you buy. Nothing here is medical advice.
How to measure
You need a soft measuring tape and two minutes. Underbust: wrap the tape directly under your bust, level and snug, breathing out normally. Bust: wrap it around the fullest part, level across your back, without pressing in. Enter both numbers above, in inches or centimetres. The full steps are in the step-by-step measuring guide.
Brazil bra size chart
| BR / EU band (cm) | US band | UK band | FR band |
|---|---|---|---|
| 70 | 28 | 28 | 85 |
| 75 | 30 | 30 | 90 |
| 80 | 32 | 32 | 95 |
| 85 | 34 | 34 | 100 |
| 90 | 36 | 36 | 105 |
| 95 | 38 | 38 | 110 |
Cups run by the difference between your bust and band measurements. One inch of difference is roughly one cup step in US and UK sizing; in centimetre systems the steps are 2.5 cm.
How Brazil sizing works
Brazilian bands in centimetres follow the EU convention (nearest 5 cm), and cups run A, B, C, D, E and beyond. A Brazilian 75B is roughly a US 34B. On some Brazilian labels you will also see numbers like 40, 42 or 44, where 42 is roughly an EU 90 — if your label uses those numbers, check the brand's own chart, because that numbering is not the centimetre system.
A worked example
A 34-inch underbust with a 3-inch difference is a Brazilian 85D, a US 34C and a UK 34C.
Converting to and from Brazil sizes
Convert a Brazilian centimetre size exactly like an EU size: a Brazilian 85D is a US 34C and a UK 34C. If your Brazilian label uses the 40/42 numbering instead, convert via the brand's chart — the two numberings do not map by a fixed rule.
Common measuring mistakes
Measuring over a padded bra lifts and compresses, giving a smaller bust reading. Measure without a bra or in a thin, unpadded one. Pulling the tape too tight underestimates the band. Letting the tape droop at the back overestimates the bust. Using an old size without re-measuring — weight, pregnancy, breastfeeding and aging all change the numbers, so re-measure every year or two.
Shopping tips for Brazil
Brazilian stores mostly label in centimetres like the EU, but some brands use the alternate 40/42 numbering. If the band number on a Brazilian label looks too high to be centimetres, it is probably the alternate numbering — check that brand's own chart before ordering.
One habit covers every system: check the system on the label, convert both the band and the cup, and try the bra on before committing to more than one. Returns are easier than a drawer full of the wrong size.
Frequently Asked Questions
What sizing system does Brazil use?
Brazilian bands in centimetres follow the EU convention (nearest 5 cm), and cups run A, B, C, D, E and beyond. A Brazilian 75B is roughly a US 34B. On some Brazilian labels you will also see numbers like 40, 42 or 44, where 42 is roughly an EU 90 — if your label uses those numbers, check the brand's own chart, because that numbering is not the centimetre system. If a label you are reading does not match this system, it is probably an import — convert it rather than guessing.
How do I convert my US or UK size to a Brazil size?
Convert a Brazilian centimetre size exactly like an EU size: a Brazilian 85D is a US 34C and a UK 34C. If your Brazilian label uses the 40/42 numbering instead, convert via the brand's chart — the two numberings do not map by a fixed rule. The global size converter does this translation for any size in one step.
What if my size is not sold, or I am between sizes?
Try a sister size: one band down and one cup up, or one band up and one cup down, keeping roughly the same cup volume. If you are between cups, start with the larger cup — you can tighten a band, but you cannot add cup volume.
Do brands in Brazil vary?
Yes. Every system is a starting point, not a guarantee: band stretch, cup depth, wire width and grading vary by brand and style. Always check the brand's own chart and try on when you can.
