How to measure your child's foot
- Place a sheet of paper on a hard floor with one edge against a wall.
- Have your child stand with their heel touching the wall, weight on that foot.
- Mark the tip of their longest toe, then measure heel-to-toe in centimeters.
- Measure both feet and use the larger measurement. Between sizes? Size up.
Frequently asked questions
How do I measure my child's foot for Nike 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 Nike chart above. If they're between sizes, size up.
What age is each Nike 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. Nike kids' shoes top out at 7Y (about 24.6 cm foot length). For larger feet, switch to the adult Nike size chart — a 7Y is equivalent to a US men's 7 / women's 8.5.
