What is a service box in tennis?

Dimensions The dimensions of a tennis court, in feet. (See metric version).

Tennis is played on a rectangular flat surface, usually of grass, clay, concrete (hard court) or a synthetic suspended court. The court is 78 feet (23.77 m) long, and its width is 27 feet (8.23 m) for singles matches and 36 feet (10.97 m) for doubles matches. Additional clear space around the court is needed in order for players to reach overrun balls for a total of 60 feet wide and 120 long. 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 (914 mm) high in the center. The court on the right side of each player is called the deuce court, while the left side is called the ad court (short for "advantage court").
