How wide and deep is the key area on a basketball court?

These measurements are designed to provide players with a defined space for offensive and defensive maneuvers.

During a free throw, players must position themselves outside the semi-circle until the ball leaves the shooter's hands. This rule prevents crowding and allows the shooter to focus without distractions. The semi-circle also helps referees easily identify violations.
At Line Marking Australia, we ensure that the free throw semi-circle is marked accurately using durable paint and precise measurements. This attention to detail is part of our commitment to upholding the highest standards in sports court marking.
