While the best way to ensure you're getting the correct shoes for your baby is to try them on, there are certainly times when that isn't possible. Maybe you're buying baby shoes as a gift, or maybe you found a deal online you just can't pass up. Whatever your reason, the following chart can help you determine which shoe size to buy for the special baby in your life.

Tips to Keep in Mind About This Chart:

  • Average age is an average. If the baby you're buying for is big for his/her age, the clothing size column may be a better indicator of what shoe size to buy.
  • European and UK baby shoe brands tend to run larger, on average, than American baby shoe brands; a size 18 EU, for example, is more like a 3.5 US.
  • Most brands have specific sizing charts for their shoes; look to see if you can find one on their website to help you make the best choice.
  • Measuring a baby's foot can be a challenge! Here is a video that shoes how to get a proper foot measurement of your wiggly little one.
