US Shoe size formula
The US shoe sizes are calculated based on the foot length:
Men shoe size = (Foot length in cm ÷ 2,54 × 3) – 24
Ladies shoe size = (Foot length in cm ÷ 2,54 × 3) – 23
EU Shoe size formula
In the EU, with countries like Germany, France, Italy, etc., the calculation for shoe size is as follows:
Foot length (in cm) + 1.5 cm extra x 1.5
Expert tip: Italian shoe size indication doesn’t add up the 1.5cm. That’s why Italian size always fits smaller.
