  • Weight: 20 ounces (approximately 567 grams)
  • Material: High-quality composite leather or genuine leather, similar to the NBA ball

In comparison, the NBA uses a ball with a slightly larger circumference and weight:

  • Circumference: 29.5 inches (approximately 75 cm)
  • Weight: 22 ounces (approximately 624 grams)

Reasons for the Smaller Ball in the WNBA

The decision to use a smaller ball in the WNBA stems from several factors grounded in optimizing performance and gameplay:

  • Grip and Control: A smaller circumference allows for better handling and control, particularly for players with smaller hands.
