What is the average shoe size of a 6-year-old girl with a small frame?

Small-framed 6-year-old girls typically have feet between 6.5 and 7.5 inches long, requiring a size 13 or 13.5 in the United States or 30 to 30.5 in Europe. Typically parents should buy a size larger rather than a size smaller if the child falls between sizes, as small shoes are linked to numerous development problems.

Children's feet grow very quickly and many adult foot problems have their origins in overly tight fitting shoes worn during childhood. Youth shoes are best worn when a child is around 5 or 6 years of age, but they should start wearing supportive athletic shoes after the age of 6, as they protect the feet during more athletic play.
