How Do Girl Shoe Sizes Work?

There are two primary types of girl shoe sizes. Girls from the age of 1 month to about 4-5 will wear toddler shoes which are usually marked with a “T,” and run from size 0T to 13T. A size 5T would be a size 5 toddler shoe. Once your girl is older and outgrows the largest size 13T toddler shoe, she will move onto “youth” or “big kid” shoes, which are usually marked with a “Y” and run from size 1-7.
Watch out: A size 1Y is larger than a size 13T.

How do Girls Shoe Sizes work?
The shoe size system for children differs greatly from adult sizes. There is no differentiation in gender, meaning that boys and girls use the same size. But kid’s shoe sizes are divided into three age groups: Small Girls, Big Girls and Youth.

There is no difference in the size between boys shoe sizes and girls, so that makes things a bit easier for parents. Girls’ and boys’ feet develop quite similarly throughout childhood, so toddler and youth shoe sizes are unisex.

When To Start Buying Womens Sizes?

You can start thinking about buying women’s sizes for your girl once she’s started to wear about a size 4Y or 5Y shoe. This is because women’s shoe sizes are actually quite similar in size to youth shoe sizes. A size 7 women’s shoe, for example, is usually equal to a size 5Y shoe, though this may vary slightly depending on the brand.

So, once your girl has started wearing a larger youth size, you can consider switching her to a women’s shoe, as long as her foot is large enough.

Are Boys and Girls Shoe Sizes the Same?

In simple terms: yes they are! If a boy wears 4Y then a girl would also wear 4Y. However, it could very well be the boys respectively girls of the same age wear different shoe sizes.
