The size of both are regulated in the Rules of Golf by the USGA and R&A. The golf ball has a floor minimum diameter of 1.68 inches, but it doesn’t have a maximum. Golf balls are made to that spec almost universally. The golf ball also cannot weigh less than 1.62 ounces.
BALL DIAMETER. The United States Golf Association specifies that a golf ball must weigh no more than 1.620 ounces (45.93g), be spherical in shape and be no less than 1.68- inches ( 42.7mm ) in diameter. This is called “The American Ball”. The “British Ball” is a teensy bit smaller, at 1.62- inches ( 41.1mm ).
In 1974, The R&A took a significant step toward uniformity when they made the larger 1.68-inch ball mandatory in their Open Championship. However, it was not until Jan. 1, 1990, just 27 years ago, that The R&A officially outlawed the smaller golf ball.

The standards of a golf ball control the ball’s spherical symmetry, size, weight, and initial velocity. In simple words, the golf ball should be round. And if it isn’t i.e if the ball doesn’t appear on the conforming golf balls list, then it’s illegal for professional play.
In the 1930s, Gene Sarazen spoke in favor a few times of going to an 8- inch hole . Jack Nicklaus has, a few times, cut 8- inch holes at his Muirfield Village Golf Club, for special events. Meantime, remember: the golf hole size is 4.25 inches because that’s the size the R&A decided, in 1891, to standardize.
Dimples on a golf ball create a thin turbulent boundary layer of air that clings to the ball’s surface. This allows the smoothly flowing air to follow the ball’s surface a little farther around the back side of the ball , thereby decreasing the size of the wake.
Though it seems sturdy enough, a golf ball’s shape changes dramatically when struck by a club. Even though the ball returns to its original shape , over time a ball will deform permanently and need to be replaced.
In many cases, math is used to place limitations on golf equipment, such as restricting the distance the ball will travel, as predicted by mathematical models. The Rules also place limits on a value called the coefficient of restitution, which measures the efficiency of the impact between a club and ball.

According to the USGA, the weight of the golf ball can not be greater than 1.62 ounces and the diameter of the ball shall not be less than 1.68 inches. The balls initial velocity cannot be greater than 250 feet per second and the ball can not go on an average, further than 280 yards carry and roll.
A golf ball is made up of mostly plastic and rubber materials. A two-piece ball consists of a solid rubber core with a durable thermoplastic (ionomer resin) cover. The rubber starts out as a hard block, which must be heated and pressed to form a sphere.
