1 Weight The weight of the ball shall not be greater than 1.620 ounces avoirdupois (45.93 gm). 2 Size The diameter of the ball shall not be less than 1.680 inches (42.67 mm). 3 Spherical Symmetry The ball must not be designed, manufactured or intentionally modified to have properties which differ from those of a spherically symmetrical ball. 4 Initial Velocity The initial velocity of the ball shall not exceed the limit specified (test on file), when measured on apparatus approved by USGA. 5 Overall Distance Standard The combined carry and roll of the ball, when tested on apparatus approved by USGA, shall not exceed the distance specified under the conditions set forth in the Overall Distance Standard for golf balls on file with USGA. * R & A (Royal & Ancient Golf Club of St. Andrews), USGA (United States Golf Association)  The characteristics of golf balls are strictly governed by rules. In addition to weight and size, these rules determine maximum initial velocity, total distance, and other characteristics, and it is within this framework that maximum vie technologically. So, what appears to be just small round objects is in fact the product of many leading-edge technologies. Ball structures break down broadly into two categories: wound balls, which are the conventional ball; and the solid ball, which made its appearance in the 1980s. In Japan, ever since Bridgestone introduced the two-piece Altus ball in 1982 and made it a huge hit, solid balls have achieved rapid penetration, and are now at the peak of their popularity, accounting for 95 percent of the balls sold in the Japanese market. Ball structure can be broadly divided into two categories: wound balls, which are a direct descendant of the Hasket ball, invented in 1898; and solid balls, which evolved from one-piece ball that was invented in 1966. Until recently, the general opinion among golfers has been that solid balls produced a hard feel at impact, and that they offered poor spin control performance. However, with the development of balls made of urethane resins, the ratio of professionals using solid balls at the 2000 US Open reached 30 percent. As such examples indicate, balls are being improved in ways that increasingly meet golfers' needs. Approximately 1,500 kinds of balls have been approved by the R&A and USGA. In addition to these, a large number of unproved balls are available on the market today. Within this universe, golfers will find balls that have made this kind of progress. The message is that golfers should take the intuitive to try new balls, rather than say "I'll play the same ball because it's the one I've used before." By doing so, they find themselves discovering balls that more closely fit their style of play.
