US Clothing sizes vary and for children’s apparel, the clothes are usually labeled according to the child’s age. Nevertheless, when it comes to defining the right fit in clothing, it’s far better to take your child’s height and weight into consideration than only using their age.

For toddlers and little kids, use the size chart which is for both girls and boys. For older children and teens, use the respective US size chart for girls and boys.

How to measure children’s clothes in 6 steps
With your tape measure in the right places, you can take the sizes and shop clothing that fits your infant properly. Most brands and types of clothing will have these sizes listed on the detailed product page. With the dimensions in hand you can find the perfect sized clothes for your children.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. Measure your child’s Hips

    Standing straight with their legs together, measure around the widest part of your child’s hips.

  6. 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.
