Kids Size Chart
Clothing by age and height, youth letter sizes, and a kids shoe size chart hub (converter + Nike, Adidas, New Balance, Skechers).
Kids shoe size chart
For kids shoes, boy shoes, and girl shoes (same foot-length chart), measure cm first, then convert US / UK / EU. Baby and toddler C sizes have a dedicated chart.
How to choose a kids size
- Measure height (and weight for babies) rather than relying on age alone.
- Match the closest row on the clothing table below.
- For shoes, measure foot length in cm and use the kids shoe size converter.

Frequently asked questions
How do I read a kids size chart?
Start with height and weight (or age as a rough guide), then match the label on the chart. Brands differ, so confirm with the product size chart when shopping.
Where is the kids shoe size chart?
Use the Kids shoe size charts section on this page for brand links, or open the kids shoe size converter to match foot length in cm to US, UK, and EU. Boy and girl shoes use the same chart. Measure feet—do not rely on age alone.
What is a youth size chart?
Youth sizes usually use letter labels like XS, S, M, L, and XL for older kids and teens. They are not the same as adult letter sizes—use height and chest, not an adult M or L.
Where is the infant or toddler shoe size chart?
Use our baby and toddler shoe size chart for US 1C–10C by foot length and age, plus the kids shoe size converter. Measure foot length in cm for the best match.
Where is the baby size chart for clothes?
Use the kids clothing size chart by age on this page (height, weight, chest) and the diaper size chart by weight for Pampers and Huggies. We do not publish pregnancy “fruit size by week” charts.
