Kids Clothing Size Chart: Baby to 14Y
Use the JONATS kids clothing size chart to compare US and EU sizes for babies, toddlers, and older kids, from 0–3M through 14Y. Check the age, height, and weight ranges shown below, then choose the size that best matches your child's current measurements.
Size & Fit
Runs true to size. If your child is between sizes, we recommend sizing up for a roomier fit and longer wear.
For the best fit, choose based on your child’s height and weight, not age alone.
