Crocs kids' shoe size chart

Crocs sizes kids' shoes by heel-to-toe foot length. 'C' sizes are Little Kids (roughly under 1 to 5 years) and 'J' sizes are Big Kids (about 5+). Crocs come in whole sizes, so measure your child's foot and pick the closest length.

How to measure your child's foot

  1. Place a sheet of paper on a hard floor with one edge against a wall.
  2. Have your child stand with their heel touching the wall, weight on that foot.
  3. Mark the tip of their longest toe, then measure heel-to-toe in centimeters.
  4. Measure both feet and use the larger measurement. Between sizes? Size up.

Frequently asked questions

How do I measure my child's foot for Crocs shoes?

Stand your child on paper with their heel to a wall, mark their longest toe, and measure heel-to-toe in cm. Use the larger foot, and match that length to the foot-length column in the Crocs chart above. If they're between sizes, size up.

What age is each Crocs kids' size for?

Sizing by age is only a rough guide because children's feet grow at different rates — always go by measured foot length. Crocs kids' shoes top out at J6 (24.2 cm, EU 36–37). For larger feet, switch to the adult Crocs size chart.
