⚠️ Approximate — sizing varies a lot between brands and men/women models. Foot length (cm) is the most reliable measure.

How the calculation works

The base is the foot length. The European scale uses the Paris point: EU ≈ 1.5 × (foot + 2 cm) of ease. The others derive from it: BR ≈ EU − 2, US men ≈ EU − 33, UK ≈ US − 0.5.

Examples

  • A 26 cm foot ≈ 40 (BR), 42 (EU), 9 (US men).
  • BR and EU sizes differ by ~2 points: BR 38 ≈ EU 40.

Frequently asked questions

How do I measure my foot?

Standing on a sheet of paper, mark from heel to longest toe. Measure both feet and use the larger, ideally at day's end.

Why does the same size fit sometimes and not others?

Tables vary by brand and model (the last differs). Use the size as a starting point and try on when possible.

Do kids' sizes use the same table?

The logic (foot length) is the same, but the ranges and cross-country equivalences differ from adults.
