What shoe size does a 7-year-old usually wear? 7-year-olds usually wear about a child’s size 1 shoe. This can obviously vary on whether or not your kid has the average size foot or not, but this is the most common shoe size for this age group.

Use the measurement (in inches) to find your child’s corresponding U.S. kid’s shoe size in inches on the chart below. So, for example, if the child is 7 years old and the foot measures 8.5 inches in length, the child would fit best in a youth size 3 shoe. Of course, kids’ shoe size measurements are not always exact.
