Kids Shoe Size Converter FAQ
How do I use this kids shoe size converter?
Choose the child size group first, then enter either a size or a foot length. The converter shows the closest equivalent in US, UK, EU, centimeters, or inches for that same group.
What is the difference between toddler, small kid, and big kid sizes?
They are separate size ranges with different numbering progressions. Toddler and baby sizes use the smallest children’s scale, small kid sizes continue that scale, and big kid or youth sizes reset to a new US numbering range.
Should I convert from foot length or from an existing shoe size?
Foot length is usually the cleaner starting point because it avoids mismatches between brand-specific labels. If you already know a size from one system, this converter helps you find the closest equivalent in the others.
How should I measure my child’s foot?
Measure while your child is standing, from the back of the heel to the tip of the longest toe, and use the longer foot if they differ. Many fitting guides suggest leaving about 1 to 1.5 cm of extra room for comfort and growth.
Why can the same EU size appear twice in a kids chart?
Children’s conversion charts often round or group sizes differently across systems, so one EU size can line up with more than one neighboring US or UK label. That is normal and does not mean the chart is broken.
Can this chart guarantee the perfect fit?
No. It gives a consistent conversion reference, but children’s shoes can still fit differently by brand, width, model, sock thickness, and growth stage. Treat the chart as your starting point and check the seller’s sizing notes when possible.
