Quick answer & tips ▾

A tennis court is 78 feet (23.77 m) long. It is 27 feet (8.23 m) wide for singles and 36 feet (10.97 m) wide for doubles, with a 4.5 foot alley on each side. The service line sits 21 feet from the net, making each service box 21 feet deep and 13.5 feet wide.

The net is 3 feet (0.914 m) high at the center strap and 3 feet 6 inches at the posts, which stand 3 feet outside the doubles sidelines. Lines are part of the court, so a ball touching any line is in. For a full court with room to run, plan on roughly 60 by 120 feet of total space.
