A 14 year old male basketball player would use an official size ball. There are 2 official sizes for men, 29.5 or 30 inches. For a 14 year old girl, it would be an official ball for women which measures 28.5 inches.
The average shoe size for a 2 year old girl is a US size 8. This size is in Adult size.
I'm 12. It's true that a 29.5 size basketball would make his game improve, but that would be a training ball for him because a training ball is a size bigger basketball then the one recommended for someone. 28.5 is the right size. I keep 2, a outdoor training ball (29.5) and a indoor regular ball (28.5).
It depends on the size of the 12-year-old girl.
There is no average shoe size for a 15 year old girl. Shoe size can vary and it depends on height.
