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.

How to use this Shoe Size calculator

  1. Select your known size system from the FROM dropdown — e.g. India / UK Size.
  2. Enter your shoe size — e.g. 8 for India/UK size 8.
  3. Select the target system from the TO dropdown — e.g. EU Size.
  4. The result appears instantly — India/UK 8 ≈ EU 42.
  5. Use to swap FROM and TO for reverse lookup.
  6. View the reference table to see your size in all 5 systems at once.
  7. For foot length measurement, switch FROM to Foot Length (cm) and enter your measured length for the most accurate size recommendation.

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.
Frequently Asked Questions
What is a shoe size converter?
A shoe size converter translates a shoe size from one regional system to another — such as from India/UK size to EU, or from US Men's to EU. Shoe sizing systems differ significantly across countries: India follows the UK system, Europe uses the EU (continental) system, and the USA has separate scales for men and women. The same physical foot length corresponds to different numbers in each system, making conversion essential when buying footwear from international brands.
Are Indian shoe sizes the same as UK shoe sizes?
Yes — Indian shoe sizes use the same scale as UK shoe sizes. An Indian size 8 is identical to a UK size 8. This system is based on the barleycorn unit (1/3 inch), where shoe sizes increment in 1/3 inch steps from a base measurement. Most Indian footwear brands (Bata, Liberty, Red Chief, Metro) follow this scale, and footwear imported from the UK is directly size-compatible with Indian sizing without any conversion.
How do I convert India/UK shoe size to EU size?
EU shoe sizes are approximately 33–34 units higher than India/UK sizes for the same foot. An India/UK size 6 corresponds roughly to EU 39, size 7 to EU 40–41, size 8 to EU 42, and size 9 to EU 43. The relationship is not a simple fixed offset because the EU system uses finer increments (2/3 cm per size, based on Paris points) while the UK system uses 1/3 inch per size. Use this converter for precise results, especially for half sizes.
How do US Men's and US Women's shoe sizes differ?
US Men's and US Women's shoe sizes for the same physical foot are approximately 1.5 sizes apart — US Women's sizes run about 1.5 larger than US Men's. So a woman wearing US Women's 8.5 would wear approximately US Men's 7. Both systems use 1/3 inch increments per size but are offset from each other. When buying men's shoes in a women's size (or vice versa), subtract 1.5 from women's to get men's equivalent, or add 1.5 to men's for women's.
What shoe size is EU 42?
EU size 42 corresponds to approximately India/UK size 8, US Men's 9, and US Women's 10.5. It represents a foot length of about 26.5–27 cm. EU 42 is one of the most common men's shoe sizes globally and is widely stocked by both Indian and international footwear retailers. If your foot measures 27 cm, EU 42 is your reference starting point, though you should try the shoe on as fit varies by brand and style.
How do I measure my foot length at home?
Place a sheet of paper on a hard floor, stand on it with your heel against a wall, and mark the tip of your longest toe. Measure the distance from the wall to the mark in centimetres. This is your foot length. Measure both feet and use the larger measurement — feet are often slightly different sizes. Add 0.5–1 cm for comfortable fit. Enter this measurement in the FROM field (Foot Length in cm) to find your size in any system.
What shoe size should I order from European and international brands in India?
For European brands (Adidas, Nike manufactured for EU market, Clarks EU sizing), use your EU size directly — an India/UK 7 = EU 40–41. For American brands listing US Men's sizes (New Balance, Converse), add 1 to your India/UK size to get US Men's (UK 7 ≈ US Men's 8). For brands listing US Women's sizes, add 2.5 to your India/UK size (UK 7 ≈ US Women's 9.5). Always verify with the specific brand's size chart as fit varies by product line.
How do I use the Shoe Size Converter?
Select your source system from the FROM dropdown — for example, 'India / UK Size'. Enter your current shoe size, such as 8. Choose your target system from the TO dropdown — for example, 'EU Size'. The result appears instantly. Use the ⇅ swap button to reverse the direction. The reference table below shows your size in all five systems simultaneously — foot length in cm, India/UK, EU, US Men, and US Women.
Do children's shoe sizes work with this converter?
This converter covers adult shoe sizes. Children's sizing uses a separate scale in all systems: UK children's sizes run from 0 to 13, then restart at 1 for adult sizes. EU children's sizes run roughly from 16 to 34 before transitioning to adult sizes. Children's US sizing similarly uses a different zero-point. For children's footwear, refer to the specific brand's children's size chart, as the conversion between systems changes across different ranges.
Why do shoe sizes differ between brands even in the same system?
Shoe sizes in any system represent a last size (the foot-shaped mould used to construct the shoe), not a direct measurement of foot length. Different brands use different last shapes, widths, and construction materials, which affects fit even at the same nominal size. A Bata size 8 may fit differently from a Nike size 8 or a Woodland size 8, even within the same India/UK sizing system. Always try shoes before purchasing when possible, especially for new brands.
What is the most common shoe size in India for men and women?
For Indian men, the most commonly sold shoe sizes are 7, 8, and 9 (India/UK scale), corresponding to EU 41–43 and foot lengths of approximately 25.5–27.5 cm. For Indian women, sizes 4, 5, and 6 (India/UK) are most common, corresponding to EU 37–39. These are based on typical stocking patterns at major Indian footwear retailers like Bata, Metro, and Khadim's. Indian average foot size is slightly smaller than Western European averages.
What is a Paris point and how does it relate to EU shoe sizes?
A Paris point is 2/3 of a centimetre (6.67 mm) — the increment used in the European/French shoe sizing system. Each EU size represents one Paris point of additional foot length. EU size 40 corresponds to a last length of 40 × 2/3 cm = 26.67 cm; EU size 42 = 42 × 2/3 = 28.0 cm. However, the actual foot length for a given EU size is typically about 1.5 Paris points (1 cm) shorter than the last size, since shoes need extra room. This is why a 27 cm foot typically fits EU 42 rather than EU 40.5.
