European sizing for clothes in E.U. countries is based on height, which must be converted from inches to centimeters (cm). In the U.K.,they use a size that is similar to the U.S. standards of sizing by a child's age, though there are some subtle differences you'll want to take note of.
When you think about it, basing clothing sizes on height rather than age is the most logical approach. After all, every 3-month-old is not the same height or weight and neither is every 5-year-old. It's a simple fact that children grow at different rates.
Use this chart to discover the size you need when shopping. You'll also want to keep in mind that buying a larger size is the best approach because kids are constantly growing and that super cute outfit will likely be a perfect fit before you know it.
