Converting child's shoe sizes to adult shoe sizes is a fairly simple process. A child's shoe size will generally be two sizes smaller than a women's shoe size. For example, a child who wears a size 3 in children's shoes will wear a size 5 in women's shoes. It's always best to measure the person's foot, however, to make sure that the shoes fit properly.

Once you know what size you wear in either women's or children's shoes, convert by subtracting two sizes from a women's size or adding two sizes to a children's size.

Tip

Always try shoes on before purchasing them.

Warning

The strategy of adding or subtracting two sizes to discern the correct size only works for US shoe sizes. Measuring the foot and using the conversion chart will work for shoe sizes in many countries.
