Shoe size by country

Several countries share identical or near-identical footwear sizing systems. The United Kingdom and India both use the British barleycorn scale. Australia uses UK sizing for men and US sizing for women. China has officially adopted European (EU/Paris Point) sizing. The United States and Canada use the identical US sizing system.

Mondopoint (ISO 9407:2019), which measures anatomical foot length directly in centimeters (used in Japan) or millimeters (used in South Korea and global ski boots), is the most objective and universal standard. Unlike imperial or continental systems, it represents actual foot length rather than arbitrary numbers.

European sizing is unisex and steps by Paris Points (2/3 cm per size). Under ISO/TS 19407:2015 tables for men, EU 42 corresponds to US Men 9.0 and UK 8.5. For women, EU 39 corresponds to US Women 8.0 and UK 6.0.

Historically, footwear manufacturing standards in India adopted the British imperial barleycorn sizing system. Under IS 1638:1969, India uses a 1:1 length match with UK sizing. In 2022, CSIR-CLRI completed a 3D foot scan survey of 100,000 participants to formulate the Bha sizing standard for Indian foot morphology.
