The basketball itself differs slightly between the leagues. The NBA uses a Size 7 ball, measuring 29.5 inches and weighing about 22 ounces, while the WNBA uses a Size 6 ball, 28.5 inches, and 20 ounces. The court dimensions remain the same in both leagues, measuring 94 feet by 50 feet with a basket height of 10 feet.

Defensive strategies also differ. The NBA enforces a defensive 3-second rule, penalizing teams if a defender stays in the lane without actively guarding an opponent. In contrast, the WNBA allows zone defenses and has no defensive 3-second violation.
