A golf ball cannot weigh more than 1.620 ounces. The USGA does not set a minimum weight for golf balls since there is no distinct advantage in playing with a lighter ball.
The diameter of a golf ball must be no less than 1.680, according to the USGA. There is no maximum size in terms of diameter, but the ball cannot exceed the weight standard.
A golf ball must be a symmetrical sphere. This also includes a golf ball's dimple pattern which must be symmetrical.
Velocity and Distance
The USGA sets standards as to how fast and far a ball can travel. These standards change as the game and technology, especially of club making, evolve.
Color and Design
A golf ball can be any color the manufacturer wishes. Most balls are white, but there is a sector of the market that likes yellow, pink and orange golf balls.
