Kids Shoe Size Conversion Chart: US to EU

Updated: February 2026

Shopping for children's shoes from European brands requires understanding EU sizing, which differs significantly from the US system. This guide provides accurate conversion charts for all children's age groups, from infants to teenagers, along with practical tips for ensuring the perfect fit.

How European Kids' Sizing Works

💡 Pro Tip: Write down the key numbers and values mentioned here – you will need them for comparison.

European children's shoe sizes use the Paris Point system, the same measurement system used for adults. Each EU size represents approximately 6.67 millimeters of foot length. Unlike US sizing, EU sizes don't reset between age categories—they continue in a single sequence from infants through adults, making conversions more straightforward once you understand the system.

Infant Shoe Size Conversion (0-12 months)

US 0.5 = EU 16
US 1 = EU 16-17
US 1.5 = EU 17
US 2 = EU 17-18
US 2.5 = EU 18
US 3 = EU 18-19
US 3.5 = EU 19
US 4 = EU 19-20

Toddler Shoe Size Conversion (1-4 years)

US 4.5 = EU 20
US 5 = EU 20-21
US 5.5 = EU 21
US 6 = EU 22
US 6.5 = EU 22-23

US 8 = EU 24-25
US 8.5 = EU 25
US 9 = EU 25-26

Big Kid/Youth Shoe Size Conversion (8+ years)

US 4.5 = EU 36-37
US 5 = EU 37
US 5.5 = EU 37-38
US 6 = EU 38
US 6.5 = EU 38-39
US 7 = EU 39-40

Understanding Foot Length in Centimeters

Many European children's shoe brands list the insole length in centimeters, which can be more accurate than size numbers alone. To use these measurements, add approximately 1-1.5 cm to your child's actual foot length to account for growth room and movement space. For example, if your child's foot measures 15 cm, look for shoes with an insole length of 16-16.5 cm.

Popular European Kids' Shoe Brands

Geox (Italy): Known for breathable shoes, Geox generally runs true to EU size but can be narrow. Many parents of children with wider feet report sizing up by half to one full size.

Superfit (Austria): Offers excellent quality and typically follows standard EU sizing accurately. They also provide width options (narrow, medium, wide) for better fit.

Primigi (Italy): Italian craftsmanship with styles that tend to run slightly small. Consider sizing up if your child is between sizes or has wider feet.

Bobux (New Zealand brand, popular in Europe): Designed specifically for developing feet and generally runs true to size with a slightly wider toe box.

Growth and Fit Guidelines for Children's Shoes

Check your child's shoe fit every 2-3 months, as children's feet can grow up to two sizes per year during growth spurts. The ideal fit has about 12-17mm (approximately 0.5-0.7 inches) of space beyond the longest toe. Press gently on the toe area while your child is standing to check for adequate room.

Seasonal and Activity-Specific Considerations

Winter boots: Consider sizing up by half a size to accommodate thicker socks, but ensure the heel doesn't slip when walking.

Athletic shoes: Active play shoes should fit snugly in the heel with adequate toe room to prevent blisters and support quick movements.

Sandals: These should fit more precisely than closed-toe shoes, as adjustable straps can accommodate slight size variations.

Avoiding Common Sizing Errors

Never rely solely on your child's age to determine shoe size—growth rates vary dramatically between children. A 5-year-old might wear anything from EU size 24 to 29 depending on individual development. Always measure feet before purchasing, especially when buying online from international retailers.

Tips for Online European Shoe Shopping

When ordering from EU retailers, look for brands that provide detailed size charts with foot length measurements in centimeters. Many European websites now offer customer reviews that include sizing feedback from parents—these are invaluable for determining if a brand runs true to size, large, or small.

Using these comprehensive conversion charts and expert guidance, you can confidently purchase well-fitting shoes for your children from European brands, ensuring comfort, proper foot development, and happy, active kids.
