How This Tool Works

The Children's Shoe Size Converter compares common kids' shoe size labels across US, UK, and EU sizing systems. Select the region you are starting from, then choose the child or youth size from the list.

The result shows the equivalent labels from the other supported regions using the reference chart shown on the page.

Input: US, UK, or EU children's shoe size.
Reference: Child (C) and youth (Y) size mappings.
Output: Equivalent sizes in the other supported regions.

Why This Matters for Shopping

Children's footwear labels vary by country, brand, and age range. A quick US, UK, and EU comparison helps narrow the size to try when buying internationally or checking a brand's chart.

Use the converted size as a starting point, then confirm with the seller's foot-length guidance when fit is critical.

Common Mistakes to Avoid

Do not mix child and adult sizes: C and Y labels refer to children's ranges and should not be read as adult sizing.
Check brand charts: some brands round EU sizes or use slightly different lasts.
Measure both feet: choose based on the larger foot and leave room for growth.
