Highest governing body International Tennis Federation First played 19th century Characteristics Court Main article: Tennis court The dimensions of a tennis court, in metric units. (See imperial version). Two players before a serve.Tennis is played on a rectangular, flat surface, usually grass, clay, or a hardcourt of concrete and/or asphalt. The court is 78 feet (23.77 m) long, and its width is 27 feet (8.23 m) for singles matchPlay of a single point Main article: Point (tennis) The players (or teams) start on opposite sides of the net. One player is designated the server, and the opposing player, or in doubles one of the opposing players, is the receiver. Service alternates between the two halves of the court. For each point, the server starts behind his baseline, between the center mark and the sideline. The receiver may start anywhere on their side of the net. When the receiver is ready, the server will serve, although the receiver must play to the pace of the server.

In a legal service, the ball travels over the net (without touching it) and into the diagonally opposite service box. If the ball hits the net but lands in the service box, this is a let or net service, which is void, and the server gets to retake that serve. The player can serve any number of let services in a point and they are always treated as voids and not as faults. A fault is a serve that is long, wide, or not over the net. There is also a "foot fault", which occurs when a player's foot touches the baseline or an extension of the center mark[27] before the ball is hit. If the second service is also faulty, this is a double fault, and the receiver wins the point. However, if the serve is in, it is considered a legal service.

A legal service starts a rally, in which the players alternate hitting the ball across the net. A legal return consists of the player or team hitting the ball exactly once before it has bounced twice or hit any fixtures except the net, provided that it still falls in the server's court. The ball then travels back over the net and bounces in the court on the opposite side. The first player or team to fail to make a legal return loses the point es and 36 ft (10.97 m) for doubles matches.[23] Additional clear space around the court is required in order for players to reach overrun balls. A net is stretched across the full width of the court, parallel with the baselines, dividing it into two equal ends. The net is 3 feet 6 inches (1.07 m) high at the posts and 3 feet (91.4 cm) high in the center.[23]

The design of the lawn tennis court has undergone much development. It was Major Walter Clopton Wingfield who, in 1873, designed a court approximate to the current one for his stické tennis (sphairistike). This template was modified in 1875 to the court shape that exists today; the markings homogeneous with Wingfield's design, with the hourglass shape of his court changed to a more linear framework.[24]

Each player uses a strung racquet to strike a hollow rubber ball covered with felt (most of the time Optic Yellow,[1] but can be any color or even two-tone) over a net into the opponent's court.

The modern game of tennis originated in the United Kingdom in the late 19th century as "lawn tennis" and had heavy connections to the ancient game of real tennis. After its creation, tennis spread throughout the upper-class English-speaking population before spreading around the world. Tennis is an Olympic sport and is played at all levels of society at all ages. The sport can be played by anyone who can hold a racket, including people in wheelchairs. In the United States, there is a collegiate circuit organized by the National Collegiate Athletics Association.

Except for the adoption of the tiebreaker in the 1970s, the rules of tennis have changed very little since the 1890s. A recent addition to professional tennis has been the adoption of "instant replay" technology coupled with a point challenge system, which allows a player to challenge the official call of a point.

Along with its millions of players, millions of people worldwide follow tennis as a spectator sport, especially the four Grand Slam tournaments (sometimes referred to as the "majors"): the Australian Open, the French Open, Wimbledon, and the US Open ents & Graphics
