Adjustable waistbands help when height and waist fall in different sizes.

How to measure before choosing a size

Measure height with the child standing straight against a wall and shoes off.

Use weight as a secondary check because children with the same age can have very different builds.

For tops and jackets, check chest and sleeve; for bottoms, check waist, hips and inseam.

If a child is between sizes, size up for growth room unless the garment is safety-sensitive or must fit closely.
