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").
The service line is 21 feet (6.40 meters) from the net. The service box is 13.5 feet (4.115 meters) wide.
One service box is 21ft. long by 13.5ft. wide.
The service area in tennis is where a player's serve must land into. It is often called a service box.
The service box is the box that is near the net that the server has to hit the ball in. For example, if I am serving on the right side of the court (also known as the "deuce" side) then I have to hit the ball over the net and into the (server's left) service box, so the ball is travelling across the court. Same goes if I am on the left side of the court (also known as the "ad" side), the ball needs to land on the (server's right) service box.
39 feet. The entire court is 78 feet with a 21 foot service box.
The service line is the line that borders the service box and is parallel to the net.
Assuming you are playing doubles, you would stand in the service box diagonal to your partner (on your side of the court). If you are standing in the right place, the serve will go past you and into the service box in front of you on your opponent's side.
The two service Boxes and the no mans land (The large box directly behind the two service boxes). Another way to put it would be everything but the outermost Lanes.
It has to land in the opposite diagonal service box (because you face the opposite diagonal service box when you are serving).
An ace occurs when a served ball lands on the other side of the court, within the service box, and the player on that side fails to even touch the ball with his racket.
into the service box diagonal from where you are standing behind the baseline
Let in tennis is when a point has to be stopped because of a distraction in the middle of a point from something like a balls rolling on to the court. A let is also where the serve hits the net and goes over into the correct service box. This rule applies to everything but the lets in World Team Tennis and Division one mens college tennis.
