How Do Baby Shoe Sizes Work?
Baby shoe sizes are simple! They start around size 0-1 (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:
- Use a ruler or tape measure. A soft tape measure works well for wiggly feet.
- Wait for the right moment. It's easiest when your baby is relaxed or even sleeping.
- 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.
- 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!
Tips for Buying the Perfect Baby Shoes
Keep these tips in mind when you're shopping:
- Leave a little room. You should be able to fit your pinky finger between your baby's heel and the back of the shoe. This gives them room to grow.
- Check the width. If a shoe seems too tight on the sides, look for a wider model.
- Flexibility is key. A good baby shoe should be flexible. Try to bend the shoe in half. If it's stiff, it might be uncomfortable for them.
- Barefoot is best indoors. When you're at home, letting your baby walk barefoot helps their feet develop naturally and get stronger.
- Check the fit often. Baby feet can grow a full size in just a few months! Check the fit of their shoes every 6-8 weeks.

Frequently Asked Questions
What size shoe does a 12-month-old wear?
Around a US 5 (UK 4.5, EU 20) for ages 12-18 months, fitting a foot about 4.75 inches (12.1 cm) long. See the age chart above, and measure, since babies vary.
What is a newborn baby's shoe size?
For 0-3 months, roughly a US 1 (UK 0.5, EU 16), about 3.5 inches (8.9 cm) long. Soft-soled shoes or booties are best at this age.
Do babies need shoes before they can walk?
Not really. Barefoot is best indoors: it helps feet develop naturally and grow stronger. Save first shoes for outdoor protection once your baby starts walking.
How fast do baby feet grow?
Very fast: a full shoe size in just a few months. Check the fit every 6-8 weeks using the pinky-finger test: you should fit your pinky between your baby's heel and the back of the shoe.
What is the average shoe size for a 6-month-old baby?
Around a US 2-3. Six months sits on the chart boundary: 3-6 months averages US 2 (9.5 cm) and 6-9 months averages US 3 (10.5 cm). Measure your baby's foot. Length matters more than age.
When should babies start wearing shoes?
When they start walking outdoors. Before that, soft booties are enough and barefoot time indoors helps feet develop. First walking shoes should be soft, flexible, and lightweight, so save structured shoes for confident walkers.
