How Do Baby Shoe Sizes Work?

Baby shoe sizes are simple! They start at size 0 (for newborns) and go up from there. The size is based on the length of your baby's foot in inches or centimeters. The biggest challenge is that sizes can vary a little between brands, which is why measuring is so helpful.

How to Measure Your Baby's Feet at Home

You don't need fancy tools! Here's how to get an accurate measurement at home:

  1. Use a ruler or tape measure. A soft tape measure works well for wiggly feet.
  2. Wait for the right moment. It's easiest when your baby is relaxed or even sleeping.
  3. Measure from heel to toe. Make sure their toes are flat and not curled up. Measure from the very back of their heel to the tip of their longest toe.
  4. Measure both feet. It's common for one foot to be slightly bigger than the other. Always use the larger measurement to pick a size!
