How to Accurately Measure Your Child

  • Height: Stand tall (without shoes) and measure from top of head to floor.
  • Chest: Measure at the fullest part in inches. 
  • Waist: Measure at the narrowest part in inches.
  • Weight: In pounds. 

Record these numbers using a standard measuring tape, then use our Size Charts (below) to find the best size! Between sizes? Order a size up to ensure the best, longest-lasting fit.
