Bra Size Calculator Mexico

Mexico commonly uses US sizing: inch bands in even numbers with US cup letters including DD and DDD. If you shop Mexican brands or US brands sold in Mexico, your US size is usually the right starting point.

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.
Mexico bra size chart
| MX / US band | EU band | FR band |
|---|---|---|
| 28 | 70 | 85 |
| 30 | 75 | 90 |
| 32 | 80 | 95 |
| 34 | 85 | 100 |
| 36 | 90 | 105 |
| 38 | 95 | 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 Mexico sizing works
Mexican labels you will see most often are US-style: bands 28, 30, 32, 34, 36, 38 and cups AA, A, B, C, D, DD, DDD, G, H. Some stores also carry European imports, so check whether the label you are reading is US or EU before ordering.
A worked example
A 34-inch underbust with a 3-inch difference is a Mexican 34C, an EU 85D and a French 100D.
Converting to and from Mexico sizes
A Mexican 34C is a UK 34C, an EU 85D and a French 100D. Because Mexico commonly uses US sizing, conversion is mostly a matter of translating the cup letters for EU and French labels.
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 Mexico
Mexican stores commonly use US sizing, but European imports sold in Mexico carry EU labels. Check the tag's system before you buy: a US 34 and an EU 85 are not the same band, even though both numbers look familiar.
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 Mexico use?
Mexican labels you will see most often are US-style: bands 28, 30, 32, 34, 36, 38 and cups AA, A, B, C, D, DD, DDD, G, H. Some stores also carry European imports, so check whether the label you are reading is US or EU before ordering. 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 Mexico size?
A Mexican 34C is a UK 34C, an EU 85D and a French 100D. Because Mexico commonly uses US sizing, conversion is mostly a matter of translating the cup letters for EU and French labels. 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 Mexico 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.
