What size is my child?

Why ranges, not one number?
UK shops label children's clothes by age but cut them to a height, and each brand rounds differently. Shoe shops' "average size by age" charts disagree by a size or so. So we show the range from more than one chart, name where each figure came from, and tell you what to measure. See how we source sizes.
