Here are some dimensions for you... by: Joe Waters - webmaster
Hey Dano,
Thanks for the great basketball question.
19'9" is the regulation for high school. The 3 point line isn't normally modified - unless the youth basketball league changes the dimensions for certain age groups.
Personally, I think most 11 year olds aren't strong enough to shoot a 3 pointer with proper shooting form. They usually have to change their form, by pushing the basketball, in order to get it to the hoop.
