How to Measure Your Child's Foot

Step-by-step visual guide showing how to measure a toddler's foot length against a wall for accurate shoe sizing - child standing with heel touching wall

Place your child's foot against a wall and measure from heel to longest toe

  1. Have your child stand on a piece of paper against a wall.
  2. Ensure their heel is touching the wall.
  3. Mark the tip of their longest toe and the back of their heel.
  4. Measure the distance between the two marks in centimeters or inches.
  5. Add about 0.5 inches (1.25 cm) for growing room.
  6. Use this measurement to find their size in the chart above.

Parent's Frequently Asked Questions

What shoe size is a 1-year-old?
A 1-year-old typically wears a US toddler size 4 or 5. Their foot length is usually around 4.5 to 4.8 inches (11.4 to 12.2 cm). However, it's always best to measure their foot for the most accurate sizing.
How often do I need to buy new shoes for my toddler?
Toddlers' feet grow incredibly fast! It's common to need a new pair of shoes every 2 to 4 months. You should check the fit of their shoes regularly, at least once a month.
Should I buy shoes that are a little big?
It's a good idea to leave a little bit of growing room, about half an inch (or a thumb's width) between the end of their longest toe and the front of the shoe. This ensures the shoes aren't too tight and allows for some growth, but avoid buying shoes that are excessively large as they can be a tripping hazard.
Do different brands have different shoe size standards?
Yes, different brands often have different sizing standards. For example, Nike shoes might run smaller than Adidas, and some brands may have wider or narrower fits. You can check our brand-specific shoe size charts or use our kids shoe size converter tool to find the right size for your child's foot length across different brands.
