Muddy Puddles Kids Size Guide with measurements for height, chest, waist, and leg.

Sizing tip: We often use European sizing along with US sizing to help guide you to the right fit. In many cases, if you know your child's height, this actually can help guide you better than age. We did the work for you so you do not have to convert- use this chart to find their height. Outerwear is made to layer over clothes- getting this right should be all the work you need to do. When looking at boots, use current tennis shoe sizing. Boot sizes are in T (Toddler) and Y (Youth)- not by age.
