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.

Effortless outfit, elevated look
Meet the everyday overalls you’ll reach for again and again. These vintage-washed denim overalls are designed with a soft, lived-in feel and a relaxed, kid-friendly shape—so your little one can move freely, play comfortably, and still look effortlessly put-together. The light blue wash gives a timeless, gender-neutral look that pairs with almost anything in your child’s closet. From daycare mornings to weekend outings, this is the kind of one-piece staple that makes getting dressed simple and stress-free.
