Size guide

Regardless of their age, every child has their own specific body type. Our swimsuits are therefore made with elastic. They come in three sizes. We find that your child's height (in cm) is usually the best indicator for their size. Let the following measurements serve as a guide:

  • Size 3-4 years : child's height between 88 and 107 cm.
  • Size 5-6 years : child's height between 108 and 116 cm.
  • Size 7-8 years : child's height between 117 and 126 cm.
