According to the rule of the Golf Game, the golf ball has a mass of 1.620 oz. (42.67 mm) and its diameter is not less than 1.680 inches. The golf ball hole is also determined according to the law of USGA and R&A. so, we can say that both the golf ball and its hole depend upon the laws of Golf Rules & Regulations.
Golf Ball Size History

Before 1980 the standard size of the golf ball was 1.62 inches while the rules are changed now and the ball is 1.68 inches in tournaments play. If we observe the difference between both of them it would be difficult for us to define that which one is bigger and which one is smaller.
In 1919 the R&A and USGA golf governing bodies were not agreed on the size of a golf ball and the reason is that there were two sizes to play. The British Ball and The American Ball were the two balls that golfers use.
Current Rules Regarding Golf-Ball-Size

- Golf Ball Diameter should not be less than 1.68 inches.
- Golf Ball Mass should not be than 1.620oz.
There are three more restrictions on symmetry, distance, and velocity.
In the past, the players noticed that old-scratched-up golf balls and the small sizes golf balls flew farther than newly polished spheres. So they started carving grooves into their golf-ball and resized them to make them fly better.
