MyKids-USA® Size Guide

For the best fit, we recommend choosing sizes based on measurements whenever possible. Every child grows differently.


Size Guide (Clothing)

Choose by height, not age. Height is usually the most accurate measurement.

  • Example: Size 66 fits up to 66 cm tall; Size 73 fits up to 73 cm, and so on.
  • Our patterns follow a standard body. If your child is chubbier or you prefer extra room, consider sizing up.

Size Guide (Shoes)

Measure foot length and select shoes by insole length (shoe sizes vary by country).

  • Add about 0.5 cm (¼″) of extra room for comfort and growth.
  • Examples:
    • Insole 11.5 cm → best for foot length around 11.0 cm
    • Insole 12.0 cm → best for foot length around 11.5 cm
  • For wider or chubbier feet, consider sizing up.
