Between two sizes? We cut with a little extra room to grow into — if your child is between measurements, we always recommend sizing up.

Two minutes, one tape measure

How to measure at home

A soft measuring tape and a helper (or a favourite toy for distraction) is all you need.

1

Height

Stand your child against a wall, heels touching the base, and mark the top of their head. Measure floor to mark.

2

Chest

Wrap the tape under the arms, around the fullest part of the chest, keeping it snug but not tight.

3

Weight

Use a home scale, or subtract your own weight from your weight while holding them — every parent's trick.
