Kids Shoe Sizes by Age

The growth of children’s feet is not only very individual, but also very rapid. Children’s feet, especially infants, can grow up to one inch a year! Prefabricated shoe size charts,  don’t necessarily match the development curve of your child’s feet. It is better to measure the size of the feet and then convert  Babies  Toddlers/Kids/Teens, rather than to rely on an average shoe size by age chart. Use data from kids shoe size by age chart only as an approximation!

Caution with children’s shoe sizes by age! Did you know that over 65% of kids are wearing shoes that are too small for their feet? Choosing your children’s shoe size by age is not the best way to find the right shoe size. Some kids develop faster than others – and depending on whether your child is smaller or larger than average for their age, these charts may not be accurate. Again, we always recommend using these charts as a “rule-of-thumb” – for the best results, you should always make sure you measure your child’s feet before shopping for shoes online!
