What is the true diameter of a golf hole?

The true diameter of a golf hole is 4 1/4 inches. This specification is established by the Rules of Golf, which are governed by organizations such as the United States Golf Association (USGA) and The R&A. The regulation size is essential as it ensures consistency in the game regardless of where golf is played. The diameter is designed to ensure that the hole is large enough for a golf ball to drop into, yet small enough to maintain the challenge of the sport. Understanding this standard is vital for maintaining compliance in both tournament play and course design. Knowing these specifications helps facility managers in golf course operations and maintenance, ensuring they uphold the standards expected in the golfing community.
