Old Navy Kids' Underwear Sizing

Measurement tips

To find your shoe size, you need a sheet of paper, a pencil or pen, and a tape measure.

Chest: With your arms relaxed, measure around the widest part of your chest.

Hips: Stand relaxed with your feet apart. Measure the widest part of your hips/seat.

Height: Stand straight with your back against the wall without shoes and with both feet together. For the most accurate results, mark the wall at the top of your head. Then move away and measure from the floor to the mark.
