Kids Shoe Size Chart — US, EU, UK, and CM by Age
Quick Answer
Kids' shoe sizes are organized by age group: infant (0-2 years), toddler (2-4 years), little kid (4-8 years), and big kid (8-12+ years). Always measure the foot — age is only a rough guide.
Children's feet grow quickly, so regular measurement is important. This chart shows US, EU, and UK kids' sizes alongside approximate age ranges and foot length in cm. Always measure your child's foot rather than relying on age alone.

Important Notes
- Kids' feet can grow 1-2 sizes per year. Measure every 2-3 months.
- Leave about 1 cm of space between the longest toe and the end of the shoe.
- Age ranges are approximate — foot size varies significantly among children of the same age.
- Have your child stand while measuring for accurate results.
