What is a Shoe Size?
A Shoe Size Converter translates a shoe size between the regional systems used in India, the UK, Europe, and the United States — India/UK size, EU (European) size, US Men's size, US Women's size, and foot length in centimetres.
Shoe sizes are not a universal measurement. Each regional system was developed independently based on different base units, different foot shapes, and different historical traditions. India and the UK use the barleycorn system, where each size increment is 1/3 inch. Europe uses the Paris point system, where each increment is 2/3 cm. The US uses a system derived from UK sizing but offset by a fixed amount, with separate scales for men and women.
The result is that the same physical foot corresponds to completely different numbers in each system. An Indian man with a UK/India size 8 shoe buys EU 42 from a German brand, US Men's 9 from an American brand, and should ask for approximately 26.5 cm from a Japanese brand using the Mondopoint system. Without a converter, every international footwear purchase requires a lookup — and getting it wrong means returns.
In India specifically, this problem is acute because the Indian footwear market has internationalised rapidly. Adidas, Nike, Puma, New Balance, and Clarks all have significant Indian presences and retail through platforms like Myntra, Flipkart, and Amazon India. European and American brands use EU and US sizing on their Indian-market pages, while domestic brands (Bata India, Liberty, Red Chief, Metro) use India/UK sizing. Pair this converter with the Length Converter for precise foot measurement cross-referencing.

Formula & Methodology
This converter uses foot length in centimetres as its canonical unit. All size systems are mapped to and from foot length using a lookup table with linear interpolation between reference points. The lookup table is based on: - Mondopoint standard (ISO 9407): foot length in mm as the scientific basis - BIS IS 1638: Indian footwear sizing standard (follows UK barleycorn) - Standard industry conversion charts from major footwear retailers Key relationships: - India/UK to EU: EU ≈ India/UK + 33 to 34 (varies by size range) - India/UK to US Men: US Men ≈ India/UK + 1 - India/UK to US Women: US Women ≈ India/UK + 2.5 - US Men to US Women: US Women ≈ US Men + 1.5 Interpolation note: Shoe sizes are discrete values in practice (you buy whole or half sizes). The converter returns the mathematically interpolated equivalent — round to the nearest half size when ordering, and when between sizes, size up for comfort. Disclaimer: These conversions are approximate industry-standard equivalents. Actual fit varies by brand, last shape, and shoe style. Always verify with the specific brand's official size chart for critical purchases.
