how high is the center of the tennis court net
Tennis Tennis is played on a rectangular, flat surface. The court is 78 feet (23.77 m) long, and 27 feet (8.2 m) wide for singles matches and 36 ft (11 m) for doubles matches.[41] 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. It is held up by either a metal cable or cord that can be no more than 0.8 cm (1⁄3 in).[42] The net is 3 feet 6 inches (1.07 m) high at the posts and 3 feet (0.91 m) high in the center.[41] The net posts are 3 feet (0.91 m) outside the doubles court on each side or, for a singles net, 3 feet (0.91 m) 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]

Centre Court The roof's ten trusses each weigh 100 tonnes, and the total weight, including non-moving parts, is 3,000 tonnes. The total area of the roof when fully deployed is 5,200 m2.[21] The cost of the roof has not been disclosed by the Club, but is estimated at £80–£100 million.[22] Another retractable roof is planned for No. 1 Court and due to be completed in 2019.
