Como usar esta calculadora

- Enter your size (half sizes allowed).
- Compare the results; for the best fit, measure your foot length and check the brand's own size chart.
Fórmula
Each system is derived from foot or shoe-last length with a different unit and starting point. US sizes step by 1/3 inch, EU (Paris points) by 2/3 cm, and Mondopoint is the foot length in centimeters.
US men = 3 × foot (in) − 22
US women ≈ US men + 1.5
UK ≈ US men − 1
EU ≈ 1.5 × (foot cm + 1.5)
Example
- US men's 9 → foot length ≈ 10.33 in (26.2 cm).
- US women's 10.5, UK 8, EU about 41.5–42.
Perguntas frequentes
Why do brands differ?
Shoe sizing isn't fully standardized. Lasts, widths and styles vary, so the same size can fit differently across brands and countries.
How do I measure my foot?
Stand on paper with your heel against a wall, mark the longest toe, and measure from the wall to the mark. Measure both feet in the evening and use the longer one.
Does this work for children's sizes?
No. Children's sizes use different scales; use a children's size chart.
