European clothing sizes are heights in centimetres, US sizes are roughly ages, and UK sizes sit somewhere between. This chart lines the three up, and the shoe sizes are ordered by foot length, the one thing you can measure at home. Enter a height or a foot length and the matching row is highlighted.

Estimate only. Brands differ by up to a full size; this is a starting point, not a measurement. Sources: the Clarks fit guide for shoes, and EN 13402 for the clothing height bands.
KidGrowth keeps a clothing and a shoe size per child with the purchase date, and marks them on this chart. Free, and the data stays on your phone.
Get KidGrowth on Google PlayEN 13402 labels children's clothing by body height in centimetres, in steps of 6 cm: 86, 92, 98 and so on. So the most accurate way to pick a size is to measure the child, not to guess from age. A three-year-old can be 92 or 104, and both are perfectly normal.
US and UK sizes are built on an approximate age (2T, 3T, 4 to 5 years), not on height. They are handy in a shop, but they assume an average child; anyone taller or shorter than average falls between them. The chart converts by the height range each label is aimed at, which is why the 104 to 110 cm row is a US 5 and a UK 4 to 5 years.
Stand on a sheet of paper, barefoot, with weight on the foot, and mark the heel and the tip of the longest toe. Measure the distance in centimetres, for both feet, and take the larger. The chart gives the smallest size that fits that length according to the Clarks fit guide; brands differ by up to a full size, so it is a starting point.
Up to age three a foot grows about half a size every two to three months; from age four, every four to six months. A shoe that is too small does not necessarily hurt, and small children do not always say. Check with a thumb at the toe, and in the app note the purchase date next to each size so you know when it is getting old.
No, and the chart says so in plain words: it is a conversion between systems, not a standard. Brands stray by up to a full size either way. Use it to know what to look for on the shelf, and measure where you can.
The youth series. In the UK and the US the children's scale runs to 13 and then starts again from 1, so 1Y is bigger than 13. In Europe the count simply continues: 32, 33 and so on.
In the app: a clothing and a shoe size per child with the purchase date, and the size guide marks on the chart where each child sits. In the supermarket you open it and see, instead of scrolling through messages.
For closed shoes. Sandals and boots are often sized differently, and sports brands tend to run small. In both cases foot length is still the right place to start.
