I am not sure what dimensions you are looking for, but it sounds like the question is dealing with the dimensions of a basketball. The most important dimension for basketballs is the circumference. The circumference tells you what size of basketball is being used, which in turn tells you if the basketball is a men's or women's ball. The circumference of a men's ball is 29.5 inches. The size is also known as size 7. The cirumference of a women's ball is 28.5 inches. This size is also known as size 6. In some youth basketball leagues, players are often started with a 27.5-inch-circumference basketball, also known as size 5. If this does not answer your question, be a little more specific on what dimension you are looking for.
