Size Chart
Size Chart
Find the perfect fit for your little one.
Every child grows at their own pace. Use our size chart to choose the right size based on your child's height and weight. All measurements are in centimeters (cm) with inches (in) in parentheses.
Best practice: choose by height, not age. Children of the same age can vary a lot in height. If your child is between two sizes, we recommend sizing up — kids grow fast!

How to Measure Body Size
- Height: Have your child stand barefoot against a wall with heels, back, and head touching the wall. Measure from the floor to the top of the head.
- Waist: Measure around the natural waistline, just above the belly button.
- Weight: Use your child's most recent weight for reference.
Helpful Tips
- Every child grows differently. Use these charts as a general reference, and always check individual product descriptions for specific fit notes.
- If your child is between sizes or you're unsure, consider sizing up for extra room to grow.
- All measurements are body measurements, not garment measurements.
- Size chart is for reference only. Slight variations may occur between different styles and manufacturers.
