Size of the ball
The “Rules of Golf” says that a golf ball’s diameter must be a minimum of 1.680 inches / 42.67 mm. A smaller ball would fly much further than a larger ball. The reason for this is simple: with a smaller diameter the ball has less air resistance, or in other words, it displaces less air as it flies. Because of this, most manufacturers produce golf balls with the minimal diameter (1.680 inches / 42.67 mm). The rules also state that the ball must be round, but I guess you knew that…

Weight of the ball
A golf ball’s weight must not exceed 1.620 oz./ 45.93 g according to the “Rules of Golf”. The heavier the ball, the greater its momentum, and the less it would be slowed down by air resistance. Hence it would tend to fly further. For this reason most manufacturers produce golf balls with the heaviest sanctioned weight of 1.620 oz./ 45.93 g.

Compression Rates
In the manufacturing process, some two-piece, and all three-piece balls are rated by their compression measurements. This is done by pressuring them with a standard weight
Balls that don’t deform at all are rated Compression 200, while balls that deform by 0.2″ or above are rated Compression 0. These are the two extremes, and between them balls are rated in intervals of 0.001 inches. The Standard Compression rate is usually 90 or 100. the higher the compression rate the harder the feel, and vice versa. Almost every ball is subject to a compression rating. Compression rates of 80 and 100 are also found.

However, manufacturers are not bound by an official standard. Hence one manufacturer’s compression rate of 100 can be different to another manufacturer’s compression rate of 100. This can mount up to a 3.5 point difference in either direction. In addition, some balls don’t even have the compression rate printed on them.

According to a host of surveys, low speed swing players are better off using balls with a Compression rate of 80. Players with an average speed swing should choose Compression 100, and Compression 110 is best for high swing speed players.

The weather should always be taken into consideration when deciding on compression rates to use. Low compression balls are best for colder weather, while high compression balls perform better in hot weather.
