Shopping & Measurement Tips
When shopping online or buying kids' shoes internationally, Chinese, European, US, and UK sizes can often be confusing. Choosing the wrong size leads to time-consuming returns and exchanges. This tool provides a standardized children's shoe size conversion chart. Simply enter the foot length (in centimeters) or select a common Chinese size to instantly view the corresponding EU, US, and UK sizes, helping parents quickly determine the exact shoe size their child needs.
This conversion chart is compiled based on universal kids' shoe size standards. Due to differences in shoe shape, toe box space, and design across brands, the actual fit may vary slightly. When measuring foot length, have your child stand up, measure the distance from the heel to the longest toe, and use the measurement of the longer foot. If thick socks or insoles will be worn, it is recommended to add a 0.5-1 cm allowance to the foot length. The data on this page is for reference only. We do not store any user-entered foot length information, ensuring your privacy and security.
Children's feet grow quickly, so it is recommended to remeasure their foot length every 2-3 months. The best time to measure is in the afternoon, as feet tend to swell slightly, which better reflects the actual wearing condition. If the foot length falls between two sizes, it is generally advisable to choose the larger size. When buying internationally, always check the brand's official size recommendations, as different brands may categorize infant and toddler sizes differently even within US sizing (e.g., jumping to size 10 after 9.5). This tool provides a standardized conversion. For example: Foot length 12.5 cm → CN 19 → EU 20 → US 4.5 → UK 3.5; Foot length 18.5 cm → CN 29 → EU 30 → US 12 → UK 11. Use this as a starting point for your purchases.
