what is the area of a tennis court
Tennis court The dimensions of a tennis court are defined and regulated by the International Tennis Federation (ITF) governing body and are written down in the annual 'Rules of Tennis' document.[1] The court is 78 feet (23.77 metres) long. Its width is 27 feet (8.23 metres) for singles matches and 36 feet (10.97 metres) for doubles matches.[2] The service line is 21 feet (6.40 metres) from the net.[2] Additional clear space around the court is needed in order for players to reach overrun balls for a total of 60 feet (18 metres) wide and 120 feet (37 metres) 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 metres) high at the posts, and 3 feet (0.91 metres) high in the center.[3] The net posts are 3 feet (0.91 metres) outside the doubles court on each side or, for a singles net, 3 feet (0.91 metres) outside the singles court on each side.

Tennis A recent rule change is to allow coaching on court on a limited basis during a match.[60][61][62][63] This has been introduced in women's tennis for WTA Tour events in 2009 and allows the player to request her coach once per set.[64]
The Championships, Wimbledon Since 2001, the courts used for Wimbledon have been sown with 100% perennial ryegrass. Prior to 2001 a combination of 70% ryegrass and 30% Creeping Red Fescue was used. The change was made to improve durability and strengthen the sward to better withstand the increasing wear of the modern game.[29][30]
