Kids’ measuring guide

Use the tips & visuals in this guide to make taking your child's body measurements easy-peasy.

Dont have a fabric tape measure? Use a shoelace or pant leg to measure. Then, lay it flat & use a ruler or tape measure to get a numerical measurement.

How to measure

  • Chest

    Have your child make airplane arms. Wrap tape measure around the fullest part of the chest, keeping it level & snug.

  • Waist

    With your child bending to one side, measure the point where the waist flexes naturally. Keep the tape level & comfortably loose.
