Brazilian shoe size from foot length in cm
Brazilian shoe sizes follow the insole length rather than the foot itself. The rough conversion is BR size ≈ foot length (cm) + 2. A few reference points help: a foot of 23 cm lands on size 35, 25.5 cm on 38, 27.5 cm on 42, and 29 cm on 44. US sizing has no single formula because the men's and women's scales differ, and European numbering runs on Paris points. There's also the Mondopoint system (ISO 9407), the international standard that states the size straight in millimetres of foot length; you'll see it on safety footwear and ski boots. One practical tip: measure your longer foot at the end of the day, when feet have swollen a bit.
Applications
Shoe e-commerce leans on this constantly — stores like Dafiti, Netshoes and Zattini use size charts that turn cm into BR/EUR/US numbers. It also shows up in custom shoemaking, school uniform supply, and fitting orthopaedic insoles. Brands such as Havaianas and Melissa publish their own cm-to-BR tables built on the same insole rule.
FAQ
Why is BR size foot length + 2? Those extra 2 cm are the toe allowance built into the insole, so your foot never touches the front of the shoe.
BR 38 equals US what? Somewhere around women's US 7.5 or men's US 6, though it shifts from brand to brand. Check the brand's own chart before buying.
Should I round up or down? When your foot sits between two sizes, go up. A shoe that's a touch loose beats one that pinches.
