The official apparatus used in professional games consists of a rim measuring 18 inches (46 cm) in diameter, suspended 10 feet (3.05 m) above the playing surface. This metal ring is attached to a rectangular backboard, typically made of tempered glass, providing a surface for the ball to rebound off during shots. Nets are affixed to the rim, aiding in visual confirmation of a successful score.
Adherence to these specifications ensures uniformity and fairness across all professional matches. This consistency allows players to develop and refine their skills based on a standardized target. The regulation height and diameter are foundational to the sport’s competitive integrity and have remained largely unchanged over decades, contributing to the game’s rich history and global appeal.
