Brazilian lingerie is a genuinely major global export industry, and its sizing sits closer to the US system than most of Latin America. Brazil generally uses band numbers in inches with letter cups following a scale close to the US standard, though some domestic brands use their own numbered scale unrelated to band/cup at all.

How Brazil Sizing Actually Works
Brazil generally uses band numbers in inches with letter cups following a scale close to the US standard, though some domestic brands use their own numbered scale unrelated to band/cup at all.
If a Brazilian brand’s tag shows a single number with no letter, it’s likely using a proprietary domestic scale — check that brand’s own size guide rather than assuming band/cup logic applies.
Convert Your Size
Use the calculator above to see your size across all 7 systems this site supports, Brazil included. If you already know your size in another system, enter it into the Global Bra Size Converter instead of doing the math by hand.
Getting an Accurate Starting Point
The conversion is only step one — How to Measure explains the exact measuring method this page assumes, and the Sister Size Calculator helps fine-tune things if your first size guess isn’t quite right.
A Worked Example: Shopping in Brazil
Say your measurements convert to a US 30C. If you’re buying an American brand, ask for exactly that. If the label is European, convert to roughly 90cm band, C cup using the Global Size Converter. If it’s an Asian import, expect a band closer to 75cm with a similar cup letter. The tag’s country of manufacture is your best clue for which conversion applies.
Shopping Locally vs. Importing in Brazil
Brazilian sizing on many local labels follows its own numeric system distinct from both US and EU charts, so imported brands are usually easier to size correctly using this page’s conversion than local ones.
Common Sizing Mistakes Shoppers Make in Brazil
A frequent Brazilian-market mistake is comparing a local numeric size directly to a US letter-based size without going through an actual conversion step first.
Another Brazilian-market slip is assuming a size that fits well in swimwear will fit identically in everyday bras, since the two categories often use different local sizing conventions.
A Note on Retail Fitting in Brazil
Specialty lingerie boutiques in Brazil’s larger cities commonly offer personal fittings, which is especially useful given the local numeric sizing system.
Brazil’s Position Within South American Sizing
Brazilian sizing isn’t part of the site’s core conversion table, and imported brands sold locally often carry their original country’s sizing rather than a Brazil-specific standard — treat any chart you find as retailer-specific rather than a universal Brazilian norm.
A Strong Domestic Lingerie Manufacturing Base
Brazil has one of the larger domestic lingerie manufacturing industries in Latin America, which means a genuinely wide range of Brazilian-made options exist alongside imported international brands — worth exploring domestic brands specifically, not just international ones.
Regional Latin American Trade Influences Availability
Brazil’s retail ties with other South American markets mean some sizing conventions and brand availability overlap with neighboring countries, though Brazil’s own domestic industry means it’s less import-dependent than some smaller regional markets.
A Strong Culture Around Swimwear-Adjacent Sizing Knowledge
Brazil’s globally recognized swimwear industry means many Brazilian shoppers are already comfortable with detailed body measurement for fit purposes, which can make adapting to precise bra measurement techniques feel more familiar than in markets less swimwear-focused.
FAQ
Often yes for internationally-styled brands, but some domestic labels use a separate numbered-only scale.
If the tag shows just one number with no letter, it's likely a proprietary size — check that brand's chart directly.
Closer to the US inch-based approach when band/cup labeling is used at all.
A converter gets you close, but cut and construction still vary by brand — treat the converted number as your starting point for trying on, not a guarantee.
Yes — conversions get less reliable at the extremes of any scale, since brands often adjust proportions rather than just scaling a size up or down uniformly.
It can add cost and delivery time, and in some cases customs duties — factor this in especially for a size you're not fully confident about, since returns get more expensive across borders.
After — get your baseline size from the calculator, then check that exact product's own chart, since retailer-wide conversions are a starting point, not a guarantee for every individual style.
Most markets have at least some domestic labels alongside international brands, but sizing conventions typically follow whichever system that specific brand was designed under, not necessarily the country it's sold in.
There's meaningful overlap due to regional trade, but always check a specific brand's chart rather than assuming exact equivalence across the region.
