Tennis

Tennis is a net sport in which one or two players a side use stringed rackets to hit a felt-covered ball over a net and into the opposing half of a rectangular court. It is played on grass, clay, hard and indoor courts at clubs, parks and schools around the world, and its rules are set by the International Tennis Federation.

Formats

  • Singles One player a side, using the singles sidelines.
  • Doubles Two players a side, using the full width of the court.
  • Mixed doubles A man and a woman on each side.

How it is played

Two players, or two pairs, hit the ball over a net and try to make it land in the opposite court so the other side cannot return it before a second bounce. Points build into games, games into sets, and a match is the best of three or five sets.
