Measuring Feet:

  1. Ask the child to stand flat footed on a piece of paper
  2. Make a mark at their longest toe and behind their heel
  3. Measure the distance between the two points using a ruler or tape measure
  4. Refer to our comprehensive footwear chart and match your measurements to their foot length
*If your child is between sizes, it’s advised to size up

Measuring the Body:

Height

  1. Ask the child to line up against the wall
  2. Tell them to stand with straight legs, arms at their side, shoulders level, and look straight ahead
  3. Place a ruler on top of their head and mark where the bottom of the ruler touches the wall
  4. Use a measuring tape or ruler to measure from the floor to the mark on the wall
  5. For the best accuracy, record the height to the nearest 1/8th of an inch or 1/10th centimeter
  6. Repeat this to ensure accuracy

Chest

  1. Measure the chest over a thin shirt. Avoid bulky tops
  2. Place the tape measure a few inches below the armpit*
  3. Make sure the tape measure is level on all sides
*Don’t pull the tape measure too tight. It should be comfortable around their body.

Waist

  1. Measure the waist over a thin shirt
  2. Tell them to relax, as measurements are most accurate in a neutral position
  3. Place the tape measure at the narrowest part of the torso*
  4. Make sure the tape measure is level on all sides
*If there is no obvious distinction, measure between the bottom of the rib cage and hip bones

Hips

  1. Have the child stand on a flat surface with their feet together
  2. Tell them to relax, as measurements are most accurate in a neutral position
  3. Place the tape measure across the fullest part of their hips and buttocks*
  4. Make sure the tape measure is level on all sides
*The tape measure should be snug around the hips
