BALLS

A golf ball is a precision-engineered piece of equipment designed specifically for the game of golf. To ensure a level playing field, all golf balls used in official play must adhere to strict regulations set by The R&A and the United States Golf Association (USGA).

Official Regulatory Standards

Under the Rules of Golf, a conforming ball must meet the following physical and performance specifications:

  • Maximum Mass: No more than 1.620 oz (45.93 g).

  • Minimum Diameter: Not less than 1.680 inches (42.67 mm).

  • Performance Limits: The ball must perform within specific velocity, distance, and symmetry limits during testing.

Testing and Approval

Just like golf clubs, golf balls are subject to rigorous testing. Balls that do not conform to these regulations are deemed “non-conforming” and are prohibited for use in any competitive play.
