How to use it
- Enter child age.
- The result appears straight away and updates as you edit.
- Copy the result, or copy a link that keeps the same values to share it.
How it is calculated
For ages a to a + 1 years: EU size = 86 + 6 × a, so age 5 gives 116. It matches the UK label "a to a + 1 years".
Example
Inputs: Child age = 5 years. Result: EU size: 116 cm; UK size (age): 5-6 years; US size: 6.
Limits and caveats
- US equivalents are approximate and brands can differ by one size.
- Height is a more reliable guide than age, since children of the same age vary in height.
Questions about this tool
My child is 5 but tall. What do I pick?
Go by height if you know it; a child taller than average needs the next size up.
What does a 5-6 years label mean?
It is made for a child who has turned 5 but not 6, around 111 to 116 cm tall.
Does the US size equal the age?
Roughly. A US 6 usually suits a six year old, but brands vary.
