Tennis Court Dimensions, Size, Diagram

Tennis court dimensions vary depending on singles or doubles play. 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.

Tennis Court Dimensions and Measurements

The quick answer for size of a tennis court for singles is 78 feet by 27 feet. For doubles, 78 feet by 36 feet.

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

Singles Match Court Size

Single players use the narrower width for the dimensions of a tennis court for singles play (designated by the inside singles sidelines). The court length is the same for singles and doubles matches.

Court length: 78 feet (23.77 meters) long.

But, the width is different.

Court width: 27 feet (8.23 meters) wide.

Doubles Match Court Size

Doubles match rules allow players to use the full court width, all the way to the outer doubles sidelines. The doubles court extends 4.5 feet beyond each side of the singles court sidelines.

Court length: 78 feet (23.77 meters) long.

Court width: 36 feet (10.97 meters) wide. At 36 ft wide, there’s 9 more feet to cover compared to the singles’ 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 Size

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 high (1.07 meters).

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

Types of Tennis Court Surfaces

There are a variety of surfaces used in the game of tennis. The major surfaces used in tennis include clay courts, carpet courts, grass courts and hard courts. Hard surface courts are the predominant surface for most indoor courts.

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.
