US Men to EU Converter

US Men's shoe sizes follow a scale where size 9 corresponds to a foot length of approximately 27 cm, with each half-size adding about 0.42 cm. The US system is used throughout North America and differs from UK sizes by approximately one full size (US 9 ≈ UK 8). Athletic shoe sizes may vary slightly between brands.

EU shoe sizes (also called Continental or Paris Point sizes) use a scale where each size increment equals 2/3 cm (6.67 mm) in foot length, making EU 42 approximately 26.7 cm. The EU system is used throughout continental Europe and is the most common international standard. Converting between EU and US/UK sizes requires knowing the foot length.
