Shoe Size Systems

Different countries use different shoe sizing systems. The main systems are US, UK (same as India), EU (Continental European), and Japanese (in cm). This converter helps you find the right size across all major systems.

Shoe size charts: US, UK, EU, India and CM

Indian shoe sizes are UK sizes — an Indian 8 is a UK 8. For men that is one half-size below the US number (US 9 = UK 8.5 = IND 8.5); for women it is two full sizes below (US 8 = UK 6 = IND 6). The only measurement that never shifts between brands is foot length in centimetres, so measure that first.

How to measure your foot properly

  1. Do it in the evening. Feet swell through the day by up to 4 % and a shoe fitted at 8 am will pinch by 8 pm.
  2. Stand on a sheet of paper against a wall, heel touching the wall, wearing the socks you will wear with the shoe.
  3. Mark the tip of your longest toe — that is not always the big toe.
  4. Measure wall to mark in centimetres. Do both feet and use the larger number; a 3–5 mm difference between feet is normal.
  5. Add 0.5–1.0 cm of toe room, then read that total off the cm column above.

Worked example

Foot measures 26.4 cm, buying online from a US site

26.4 cm + 0.7 cm toe room = 27.1 cm of internal length needed.

On the men’s chart 27.0 cm is a US 9.

The same shoe is a UK 8.5 and an EU 42.5.

Order US 9 / UK 8.5 / EU 42.5 — and size up half if the shoe is a narrow-lasted formal or a running shoe.

Why the same number fits differently

EU sizing is based on the Paris point (2/3 cm) and measures the last, not your foot, so a French dress shoe and a German trainer marked 42 can differ by a full centimetre inside. US and UK sizes both use barleycorns (1/3 inch) but start counting from different zero points, which is where the half-size men’s offset and the two-size women’s offset come from. Japanese sizing sidesteps all of it by printing foot length in cm directly.

More questions people ask

What is US 9 in Indian shoe size?

US men’s 9 is Indian 8.5, because Indian sizing follows UK sizing and UK is half a size below US for men. US women’s 9 is Indian 7.

Is Indian shoe size the same as UK?

Yes. Indian footwear sizing is UK sizing, and most Indian brands print both numbers on the label. India also has its own BIS scheme, Bha, announced in 2024 to replace UK sizing with a foot-length system, but UK numbering is still what almost every shop stocks.

How do I convert cm to shoe size?

Measure heel-to-longest-toe in cm, add 0.5–1.0 cm of toe room, then read that total off the cm column. 25 cm plus 0.7 cm of room is a men’s US 7.5 to 8.

Are men’s and women’s shoe sizes the same?

The numbers are not. For the same physical shoe the women’s US number is about 1.5 higher than the men’s. Women’s lasts are also cut narrower through the heel, so a unisex sneaker in a men’s size often feels loose at the back.

Should I size up for running shoes?

Usually yes, by half a size. Feet lengthen under load and swell over a long run, and most running brands recommend a thumb’s width of space in front of the longest toe.
