Brazil to US Shoe Size
Use the maker’s measured foot-length chart to resolve fit; do not treat the generic JP/CM shoe label as that measurement.
Label comparison, not a foot-length chart. JP/CM is a printed shoe size label; it is not the length of your foot measured with a ruler. For a measured foot length in cm or inches, open the footwear maker's separate Foot Length or Heel-to-toe chart to choose a size. The US/UK/EU references here are approximate and vary by brand.
| JP/CM shoe label | US Men | US Women | UK | EU |
|---|---|---|---|---|
| 22 | 4 | 5.5 | 3.5 | 36 |
| 22.5 | 4.5 | 6 | 4 | 36.5 |
| 23 | 5 | 6.5 | 4.5 | 37.5 |
| 23.5 | 5.5 | 7 | 5 | 38 |
| 24 | 6 | 7.5 | 5.5 | 38.5 |
| 24.5 | 6.5 | 8 | 6 | 39 |
| 25 | 7 | 8.5 | 6.5 | 40 |
| 25.5 | 7.5 | 9 | 7 | 40.5 |
| 26 | 8 | 9.5 | 7.5 | 41 |
| 26.5 | 8.5 | 10 | 8 | 42 |
| 27 | 9 | 10.5 | 8.5 | 42.5 |
| 27.5 | 9.5 | 11 | 9 | 43 |
| 28 | 10 | 11.5 | 9.5 | 44 |
| 28.5 | 10.5 | 12 | 10 | 44.5 |
| 29 | 11 | 12.5 | 10.5 | 45 |

Brazil to US: start with the BR label and wearer category
Nike Brazil's adult men's chart lists BR 39 → US Men's 7.5 (25.0 cm measured foot). In Nike Brazil's women's chart, BR 39 instead maps to US Women's 9 (25.4 cm measured foot). The category changes the answer.
These are Nike Brazil examples, not a universal BR-to-US equation. If a seller publishes a BR chart without an accompanying US column, consult that product's own chart and distinguish shoe-label CM from physical foot length.
How to use the general reference chart on this page
The table above compares approximate US men, US women, UK, EU and JP/CM printed shoe-label references. It does not provide a direct country-specific size column. The brand-specific example above supplies a checked local-label answer; confirm it against the actual product chart before buying.
Keep foot length measured from heel to longest toe separate from CM/JP or millimeter numbers printed as shoe size labels. Those may be different quantities even when both contain the unit cm or mm.
How this guidance is checked
These sources support the measurement method and help check real-world variation. They are not presented as one universal brand-size table.
- ISO 19407:2023 — Footwear — Sizing — Conversion of sizing systems — International Organization for Standardization (ISO). Measurement-first footwear methodology and the limitation that cross-system conversions are guidance rather than guaranteed fit.
- Men's Footwear Size Chart — Nike. Manufacturer cross-check showing that foot length, labeled CM values, width, and brand-specific sizing conventions are distinct concepts.
- Footwear Size Guide — adidas. Manufacturer cross-check across heel-to-toe length and US, UK, EU, and Japan-labeled footwear sizes.
- Tabela de medidas — calçados BR/USA — Nike Brazil. Brand-specific BR-to-US men and women published size rows with explicitly separate foot-length numbers.
