A great thing about playing tennis is that you only need a racquet and a ball to play it (and a wall) & the equipment has been dramatically inproved during the years. The raquet is basically a handle attached to a elliptically frame holding a net of tightly pulled strings. From the invention of the game up to the late 80’s, the racquets were made of wood to a standard size. Then new techniques caught up and materials as metal, carbon graphite, ceramics and titanium made the racquets both
lighter and stronger. Vibration dampers was interlaced for improved feel and the handles was customized to improve the grip. The hitting area became bigger and bigger and rules had to be inplied to control the development. By today the racquets has to follow these guidelines: The hitting area (frame with strings) must be flat and generally uniform in its shape. The size of the hitting area must not be bigger than 29 inches in length (changed in 1997 from 32 inches in lenght) and 12.5 inches in width. The tennis racquet must be of a fixed shape, weight, weight distribution and size. No energy source is allowed in the racquet. The racquet is not allowed to provide any kind of instruction, advice or communication to the player during the game. The ball: A tennis ball is made of a felt coating over a hollow rubber ball. The balls are in Optic Yellow to improve visibility. (the balls were tradititionally white, but the color was changed in the middle of the 20th century). The court: The tennis court is played on a flat, rectangular surface with the dimensions 78 feel long and 27 feet wide (36 feet for double matches). The court is divided into 6 different rectangles (3 on each side). The net divides the court with a high at the posts of 3 feet 6 inches and 3 feet in the middle (due to the weight of the net). The service ”boxes” (in which the serve has to bounce first) is used alternately when the players change position after a point. Each ”service box” measures 21 feet in length & 13.5 i width.
