Read the row, not the number. Every row above describes one physical foot length, and the four columns beside it are simply four ways of naming it. An EU 42 is a UK 8, a US men's 8.5 and a US women's 10, because all four are built for a 26.2 cm foot. If a retailer only publishes one system, find your foot length in the last column and read across.

Ages in the kids chart are indicative only. Children of the same age can be several sizes apart, so measure the longer foot and add about half a centimetre of growing room. See how to measure shoe size.

Shoe sizes are one of the most confusing conversions in fashion because three different systems are all in common use and none of them line up neatly. The United States uses one scale for men and another for women that sit about a size and a half apart. The United Kingdom uses a single numeric scale close to the US men figure, and Europe uses the Paris point system, where each size is two thirds of a centimetre.

The one thing all of these have in common is foot length. Every size in the chart below is tied to a foot length in centimetres, so the surest way to get your size right in any country is to measure your foot and read across. If you know your size in one system already, the converter above will translate it instantly.

Reading the chart is easier once you know the three relationships it encodes. US women's numbers sit exactly 1.5 above US men's numbers for the same foot, so a men's 8 and a women's 9.5 are one shoe. US men's numbers sit half a size above UK numbers, which is why UK 7.5 and US men's 8 share a row. EU numbers climb faster than both, because a Paris point is two thirds of a centimetre while a barleycorn is a third of an inch, so the gap between the EU number and the UK number widens as feet get longer.

Children's sizing is a separate scale that restarts partway through. Little kids' numbers run from 0 up to about 13, then the youth range starts again at 1Y, which is why a kids 13 and a youth 1Y are only about a centimetre apart. The kids chart on this page keeps the whole progression in one place with the foot length beside it, and each size links to a page of its own.

Which number is on the box

Most shoes carry two or three numbers on the label inside the tongue, usually the US, UK and EU sizes, sometimes with a centimetre figure alongside. That centimetre figure is normally the length the shoe is built to fit rather than the internal length of the shoe itself, which is a little longer. Where a brand publishes an insole length instead, expect it to read about half a centimetre to a centimetre above the foot length in the chart above, since a shoe needs that room in front of the toes.

The UK to US relationship is the one place where published conversion charts genuinely disagree. Some put the US men's number half a size above the UK number, which is what this chart uses, and others put it a full size above. The two conventions never differ by more than half a size, and both agree on the foot length, so when a retailer's own chart contradicts this one, go by centimetres and you will be right either way.

Shoe size questions

How do I convert EU shoe size to US?

Match the EU number to the foot length, then read the US column. For example EU 39 is a 24.5 cm foot, which is a US women's 8 or a US men's 6.5. Use the converter above for an exact reading.

Why are US men and US women shoe sizes different?

The two scales share a starting point but are offset, so a woman's US size runs about 1.5 larger than the man's US size for the same foot length. A women's 9 and a men's 7.5 are the same shoe.

Is UK the same as US shoe size?

No. UK sizes run smaller than US sizes: in the chart above a UK 8 is a US men's 8.5 and a US women's 10. The UK scale is a single number used for both men and women. This is also the one relationship where published charts disagree, since some brands put the US men's number a full size above the UK number rather than half a size, so compare foot length in centimetres when the difference matters.

Should I size up or down between systems?

Convert by foot length rather than by rounding a number. If you fall between two sizes, size up, since a slightly long shoe is more wearable than a short one.

How do I convert cm to shoe size?

Measure the longer foot from heel to longest toe in centimetres, then find that length in the foot length column. A 24.5 cm foot is a UK 6, an EU 39, a US women's 8 and a US men's 6.5. If your measurement lands between two rows, take the longer size.

What is EU 42 in US and UK shoe size?

EU 42 is a 26.2 cm foot, which is a UK 8, a US men's 8.5 and a US women's 10. EU 42 is the single most searched conversion on this site, and it sits almost exactly in the middle of the adult range.

Are men's and women's shoes the same width?

Not usually. Length converts exactly between the men's and women's scales, but women's lasts are generally cut narrower at the same length. If you are crossing between the two ranges, convert by length first and then check whether the brand offers a width option.

When do kids move into adult shoe sizes?

Around a youth 7, which is a 25 cm foot, the same length as an adult US men's 7 or women's 8.5. From there the adult chart takes over at identical foot lengths, so converting by centimetres is the safest way to make the jump.
