The free throw line is 15 feet from the plane of the backboard, which is effectively 4.57 meters from the backboard. This distance is standard across NBA, NCAA, and international play, with the line drawn parallel to the endline and located inside the three-point area. Key points:

• Distance from backboard to free throw line: 15 feet (4.57 meters).

• The line runs parallel to the endline and marks the foul line for attempting one free throw after certain fouls.

• The exact position is measured from the front plane of the backboard to the free throw line, not from the hoop’s center, though the hoop itself sits 10 feet above the floor.
