Seen with the eyes of an ordinary golfer sizes of golf balls have hardly changed throughout the ages. Nevertheless, there are and have always been differences in sizes, in the recent years mainly two sizes. Before the 1980′s the common size was 1.62 inches (4,11 cm), while soon after the size of 1.68 inches (4,27 cm) was standard. Nowadays, in tournaments there is only the standard size of 1,68 inches allowed and in shops there is generally no other size available.
