All measurements are in inches and pounds, unless otherwise noted. 

How to measure your child

Have your child stand up tall, legs together, arms at sides. Keep your tape measure parallel to floor as you measure each area.


Slide a measuring tape under your child's arms and measure around the widest part of the chest and back. 


Measure the natural waistline, which is the narrowest point of the torso, at or near the belly button. 


Measure around the widest part of your child's hips.
