1. Standard Tennis Court Dimensions

Tennis court dimensions are defined by the International Tennis Federation (ITF). The International Tennis Federation (ITF) distinguishes two types of tennis courts: recreational tennis courts and tournament tennis courts. The court’s dimensions are the same for both, but there are significant differences in the amount of space required around the tennis court. We’ll go over that in more detail later. All dimensions in this article are based on the official ITF Tennis Rules.

Key Tennis Court Dimensions

Tennis courts are 78 feet by 36 feet. However, only doubles matches are played on the entire court. The singles court is 78 feet long and 27 feet wide. Every court is made up of several components, so let’s have a look at each one.

2. Lines of a Tennis Court

  • Baseline: 27 feet (Singles) / 36 feet (Doubles) – The baseline runs parallel to the net and forms the farthest boundary, or back of the court, on each side.
  • Center Mark: 4 inches long – When a player is serving, they must serve diagonally across the court and stand on the respective side. Hence there is a little line called the center mark at the midpoint of each baseline.
  • Service Line: 27 feet wide – The service line runs parallel to the net and marks the midway point between the net and the baseline. It also marks the end of the service boxes.
  • Center Service Line: 21 feet long – The centerline is the line that runs perpendicular to the net from its center, dividing the service boxes and defining the deuce and advantage sides of the court.
  • Singles Sidelines: 39 feet long – The singles sidelines mark the outer limits of the side of the court during a game of singles.
  • Doubles Sidelines: 39 feet long – The doubles sideline runs along the outer edges of the court when the full width of the court is in use for doubles matches.

The white lines that mark the court are also uniform in thickness. All court lines should be at least 2 inches wide, with the baseline being up to 4 inches wide.

3. Areas of a Tennis Court

  • Tennis Court Area – A tennis court’s overall playing surface area is 2,106 sq. ft in singles and 2,808 sq. ft in doubles.
  • Service Boxes: Each service box is 21 feet long and 13.5 feet wide. The service boxes are the spaces between the net and the service lines. The singles sidelines define their boundaries, while the center service line divides them into left and right boxes.
  • Backcourt / No Man’s Land: 18 feet x 27 feet. This unofficial name refers to the area between the baseline and the service line, which is the largest box on a tennis court.
  • Double Alleys: Each double alley is 39 feet long and 4.5 feet wide. These boxes differentiate a court from a singles and doubles game. The alleys are only used for doubles games.

4. Tennis Net Facts & Numbers

During a match, a tennis net separates one side from the other, and the players or teams begin on opposing sides of the net. It spans the entire width of the Tennis Court. It runs parallel to the baselines and splits the court into two equal halves. A wire or metal cable holds the net up. 

The International Tennis Federation (ITF) standard tennis net measurements are 3.51 ft high at the posts and 3 ft high in the center, with a net width of 41.99 ft between the posts.

5. Frequently Asked Questions

What is The Tennis Court Size for Children?

The ITF has defined tennis court dimensions for children, which vary according to age. For example, children under the age of ten should learn to play tennis on smaller courts. Children’s courts are available in two sizes.

  • Under the age of ten: 59ft x 21ft wide.
  • Under the age of eight: 36ft x 18ft wide.

What about the area outside the primary playing surface?

While the overall playing area is 78ft by 36ft, some space beyond the playing surface is required for various reasons. At no level do you want players’ momentum in a rally to end in a crash, and even at the most professional level, extra room is required for the chair ump, ball boys, and line judges.

The ITF has also specified the minimum space (length and width) required beyond the playing area. It must extend at least 27ft beyond the baseline and be at least 18ft on the side. It’s the specified minimum size, and at different levels of tournaments, this may change depending on availability.

Are there different sizes of tennis courts?

All registered tennis club courts and tournament courts are the same standard sizes. Only the space around the courts varies from one court to the next. There are minimum requirements for the area surrounding a court at the tournament level, but it can vary greatly at the recreational level.

What are the four different types of court surfaces?

There are four types of court tennis court surfaces: hard tennis courts, clay tennis courts, grass courts, and synthetic tennis courts. The hard tennis court is constructed of asphalt and concrete. The French Open takes place on a clay court. The grass tennis court is also known as a lawn court. A synthetic court is a court made of artificial grass.

What is the width of the lines on a tennis court?

A tennis court’s lines should be at least two inches wide, with a baseline at least four inches wide.

What is the height of an indoor tennis court?

An indoor tennis court’s minimum height is 29.53 ft above the net line. The ceiling should be 18.86ft above the baseline and 13.12ft above the runback’s back end (the distance behind this baseline). These areas must be free of obstructions.

How much space is required to construct a tennis court?

The minimal amount of space required depends on whether the court is utilized for competitive or recreational purposes. The minimum length for recreational usage is 114 feet (34.8 meters), and the minimum width is 56 feet (17.1 meters). 595.1 square meters in total.
