According to the United States Golf Association, the official weight of a golf ball should not exceed 1.620 ounces, or 45.93 grams. The ball's diameter should not be less than 1.680 inches, or 42.67 millimeters.

Golf balls manufactured at the official weight and diameter have lower air resistance when in flight, according to Knet Golf. A golf ball's conformity to official weight and diameter can be tested by apparatuses like Ohaus electronic scales, laboratory balance scales, insulated ring gauges, ball tracks, incubator and test balls. Balls by top brands Nike, Callaway, Srixon, Titleist, Volvik and Wilson conform to official standards.
