How to measure children’s clothes in 6 steps

- Measure your child’s Height
Get your child to stand barefoot against a wall or a door. Measure from their heel to the top of their head. It can be easier to make a mark on a wall or doorframe and measure their height from there – it’s also fun to track how much they’ve grown over time.
- Measure your child’s chest size
Wrap a measuring tape around your kid’s chest. Place the measuring tape just under the arms at the widest point. It’s best to leave some room for extra comfort.
- Measure your child’s chest size
The waistline is situated just above the hips. Measure around the natural waistline with measuring tape. Hold the tape a little loose for a comfortable fit.
- Measure the Inside leg of your kids
The best result is with your child wearing shoes. This will give an idea where the trousers will rest above your kid’s shoes. Measure from the top of the thigh to where the bottom of the trousers should end.
- Measure your child’s Hips
Standing straight with their legs together, measure around the widest part of your child’s hips.
- Taking your child’s Neck measurement
Carefully wrap the measuring tape around your child’s neck where the collar will sit. Place 2 fingers in between the tape so it’s not too tight a fit.
