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 dress was even prettier in person. The embroidery looked delicate and expensive, and the butterfly back made it feel so special.”
Sophie Bennett

“I bought this for my daughter’s birthday photos, and it photographed beautifully. It looked full and dreamy without being too puffy.”
Hannah Mitchell

“The back butterfly detail is stunning. It did not look flimsy at all, and the overall workmanship was much nicer than I expected.”
Claire Donovan
Verified Buyer
“This is one of those dresses that looks dressy enough for a wedding but still comfortable enough for a child to move around in. We got so many compliments.”
