Tennis Court Dimensions, Size, Diagram

Tennis court dimensions vary depending on singles or doubles. Singles tennis uses the inner sidelines for determining an out-of-play shot and doubles tennis utilizes the full court width out to the outer, or doubles sidelines. The court size can also vary based on age of players.

Popular tennis court surfaces include: grass, clay, carpet and asphalt. Each surface has its own unique characteristics. A key aspect is how quickly the ball moves on the surface. Grass and hard court surfaces tend to play fast while clay plays slow.

Tennis court dimensions and measurements

The International Tennis Federation (ITF) determines the official dimensions and measurements for tennis courts. Here are dimensions for a regulation, adult-size tennis court.

Service area

A center service line divides the service area on each side of the net into two rectangles. These areas represent the space in which the served ball must land. The size of each area is the same for both singles and doubles matches.

Service line location: 21 feet (6.4 meters) from the net

Service area dimensions: 13.5 feet wide x 21 feet long (4.1 meters wide x 6.4 meters long)

Tennis net dimensions

The tennis net stretches across the width of the court, dividing it equally. The net is attached to posts on either side of the court. The center point of the net is about 6 inches lower than its height at the posts due to it’s weight. The net posts are located 3 feet (.91 meters) outside the sideline for both singles and doubles matches.

Tennis court net height at posts: 3 feet 6 inches (1.07 meters) high

Tennis court net height at center: 3 feet (.91 meters) high
