New Balance Kids' Sizes Explained: Toddler, Little Kid and Big Kid

New Balance Kids' Sizes Explained: Toddler, Little Kid and Big Kid

New Balance kids' shoes come in three size ranges: toddler (US sizes up to 10), little kid (10.5 to 3) and big kid (3.5 to 7). The numbers restart after 13, so a little kid size 1 is bigger than a size 13. The surest way to choose is to measure your child's foot in centimetres and match it to New Balance's chart, then size up if they're in between.

The three size ranges

Range US sizes Rough age Foot length
Babies and toddlers Up to 10 Up to about 4 Up to 16 cm
Little kids 10.5 to 13, then 1 to 3 About 4 to 8 16.5 to 21 cm
Big kids 3.5 to 7 About 8 to 12 21.5 to 25 cm

Ages are New Balance's rough guide. Feet vary a lot, so go by length, not age. In our listings, sizes up to 13 are marked C and sizes from 1 up are marked J, with the EU size alongside.

How to measure at home

  1. Measure late in the day. Feet are at their biggest in the late afternoon.
  2. Have your child stand on a sheet of paper with their weight on both feet, heel against a wall.
  3. Mark the tip of the longest toe, which isn't always the big toe, and measure from the wall to the mark in centimetres.
  4. Measure both feet. Use the bigger one.
  5. Find the size on the table above. If the measurement falls between two sizes, choose the larger.

How to check the fit

  • Toe room: with your child standing, there should be about 1 to 1.25 cm between the longest toe and the end of the shoe.
  • Heel: snug enough that the heel doesn't slip out as they walk.
  • Midfoot: snug, not tight. Hook-and-loop and bungee closures let you adjust this.
  • Width: most of our New Balance listings are standard width (M). The NEW-B FIRST is wide (W), worth trying if standard widths feel tight across the top or sides.

Kids' feet can grow up to half a size every 2 to 4 months, so check the fit about once a month, especially for toddlers.

Not walking yet? Babies learn to walk best barefoot, and soft booties that stay on are enough until then. Shopping for daycare? Our guide to daycare indoor shoes covers what most centres ask for.
