Understanding the Context

What Size Should My Baby’s Shoes Be?

Unlike adult shoe sizing, baby shoe sizes are measured in centimeters, and they differ significantly from international youth or adult sizing systems. Typically, newborn feet are around 6–8 cm (2.4–3.2 inches), and baby shoe sizes start around 35–38 cm (14–15 inches) and increase gradually by ~1 cm per child.

For newborns to 12 months, baby shoe sizes commonly range from 36 (35 cm) to 50 (49 cm) in metric, with common sizes like 36, 37, 38, 39, and 40. However, sizes vary between brands—some brands run small, others loose—so always use a trustworthy baby shoe size chart tailored to your intended retailer.

How to Measure Your Baby’s Feet Correctly

Measuring your baby’s feet is quick and easy, and your baby shoe size chart depends on an accurate measurement. Here’s how to do it:

Use a Flat Surface & Paper: Place a piece of paper on the floor and have your baby stand barefoot against it.
Mark the Longest Toe: Use a pencil to mark the tip of the longest toe (usually the right foot).
Measure from Heel to Toe: Use a soft ruler or measuring tape to measure from the start of the heel to the marked toe tip.
Record the Centimeter Value: Convert this measurement to the nearest standard baby shoe size using a reliable chart (example chart below).

Tip: Measure both feet — babies rarely grow symmetrically. Choose the larger size for safety and comfort.

Understanding Baby Shoe Size Charts by Brand

Many brands use slightly differing sizing systems. Here's a general guide based on common centimeter ranges:

| Centimeters (cm) | Approximate US Baby Shoe Size | Approximate UK/Europe Size |
|------------------|-------------------------------|----------------------------|
| 35 – 37 | 36–37 | 35–36 (short) / 36–37 (long)|
| 38 – 40 | 37–38 | 37–38 |
| 41 – 44 | 39–40 | 39–40 |
| 45+ | 41+ | 40+ |

Important: Always check the specific brand’s size guide — a size 38 in Brand A might be ¼ size smaller or larger than Brand B’s size 38.

Practical Tips for Selecting Baby Shoes Based on Size Chart

Buy with growth in mind: Opt for slightly roomy shoes — baby feet swell during the day.
Prioritize squiggle or roomy styles: Especially for newborns and toddlers, flexible, soft-soled shoes allow natural movement.
Check for fit: There should be a thumb’s width between the toe and shoe front — not too snug, not tight.
Test for comfort: Shoes should flex easily at the toes without pinching or rubbing.
