High School= 21 feet, NCAA= 22 feet and the NBA= 25 feet.

In High School basket ball the backboard is 15 feet from the back of the free throw line and the 3 point line is an additional 6 feet from the three throw line. So the answer is 15 feet plus 6 feet for a total of 21 feet. The High School 3 point Arc radiates 19 feet 9 inches from the center of the goal to just behind the arc.

In the NCAA you add 1 foot to the above answer for a total of 22 feet, and for the NBA you add an additional 3 feet the NCAA total for a grand total of 25 feet to the back board.
