Quick example

Imagine your toddler is about 100 cm tall and very active but not especially big or small for their age.
That child will usually be the target fit for size 100 in brands that use centimeter-based sizing.

Always check the specific brand’s size chart and your child’s actual height, since age labels are only rough guides.
