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.

This set is even prettier in person. The fabric has a nice texture, and the ruffle sleeves make it look really sweet without being too dressy. My daughter wore the cream one for a family lunch and got so many compliments.

I was pleasantly surprised by how nice this set looked in person. It has that boutique-style look but is still practical enough for regular outings. We paired it with white shoes and a small bow, and it turned out so cute.

Such a cute set for spring and summer. The wide leg pants give it a more elevated look, but it still feels light and easy for little kids to wear. We bought the pink color and it looked adorable with simple sandals.

This outfit was perfect for our vacation photos. The top is very pretty, and the matching pants make the whole look feel polished. My daughter was comfortable in it, which is always the most important thing for me.
