Kids/Toddler measuring guide

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

Don’t 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

  • Height

    Standing with feet together and back to a wall. Measure from floor to the top of the head.

  • 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.

  • Hip

    Have your child stand like a tall tree with feet together. Measure a level line around the fullest part of the hips & seat.

  • Inseam

    Take a pair of pants that fit your child well. Measure along the seam from crotch to leg opening.
