Polo Ralph Lauren Kids size chart

1. Measure your child's height without shoes, standing against a wall.
2. Find that height in the Height column, or enter it in the size finder on this page. The size on that row is the one the brand's chart gives for that height.
3. If the height is at the edge of a range, or between two sizes, look at the other measurements the chart lists, such as waist, and compare them with your child's. In the Outgrow app you can enter your child's measurements and get a full size check.
4. Age labels are only a guide. Each size on the chart is listed with a height range.

Brands compared is the number of brands whose figures for that measurement enter the comparison. The figures compare chart measurements and say nothing about how clothes fit.
