How Biometric Kids’ Conversion Works

Children’s fashion conversion follows a mathematical relationship based on average physical development. Each US size (e.g., 2T, 4T) corresponds to specific height measurements for clothing or foot length for shoes, allowing for precise transitions between EU and international standards.

Frequently Asked Questions (FAQ)

How do European kids’ sizes work?

Unlike the US, the European standard (EU) uses the child’s height in centimeters (e.g., 80, 92, 104 cm) as the primary size number.
