The American, British and Australian kids’ sizes are based on the age of the child. For example, a size 6 would be for a child who is six years old. Some US sizes include a “T”, which stands for toddler.

In Europe the size is based on the child’s height in centimeters. European sizing tends to be slimmer and more fitted than American sizing. So, if your child is on the heavier side, you may need to size up.


It’s important to note that children’s clothing sizes can vary slightly between brands, so it’s always best to also check the specific brand’s size chart to ensure a proper fit. Additionally, children can grow quickly, so it’s important to regularly check and update their clothing sizes as needed.
