How to Measure

Measuring yourself or someone else? Hold the measuring tape level with the floor - not too tight, not too loose.

Length

Measure from the top of the baby's head to the bottom of their feet. If able, have your child stand straight up with their back against the wall.

Weight

Weigh your child and round up to the nearest pound or kilogram.

Chest

With your child's arms relaxed at their sides, measure around the fullest part of their chest under their arms.

Waist

Measure around the narrowest part of your child's natural waist.

Inseam

Measure your child around their body at the fullest part of their hip / seat.
