About Tennis Courts

Tennis Court

Tennis courts surfaces are very diverse in type and makeup. Tennis courts can vary in terms of the material that makes up it’s surface, which can have a range of effects on the way the game is played. This piece discusses different types of tennis courts, their benefits and downsides, top brands, as well as the main court markings.

Benefits of Tennis Courts

Tennis courts are the foundation of the sport itself, providing a practical playing surface for the players. The courts are marked by various lines that create playing boundaries for both singles and doubles. These markings also help the court’s dimensions, which consist of 78 feet in length, 27 feet in width for singles, and 36 feet in width for doubles. The court is divided in the middle by a net that stands 42 inches tall on the sides and gradually decreases to 36 inches in the middle. The surface of the courts are typically made of grass, clay, or asphalt on “hard courts”, but it is also possible to find carpet courts. This material composition of the surface of these courts can create a range of effects on the play of the sport, including bounce height, speed of the ball, and the upkeep needed to maintain court conditions. Without court markings, the net, and the surface of the court itself, it is impossible to enjoy this globally popular sport.

There are many different types of tennis court surfaces, including clay, grass, carpet, and asphalt, that can affect a range of factors from bounce to court maintenance.


clay tennis court

Clay courts are generally more durable and are considered to be a premium type of court. The properties of clay allow players to be more agile on the court, limiting stress on joints and even allowing for the ability to slide to reach balls. Clay typically results in slow bounces, which allows quick players more time to return shots.


  • Durable playing surface
  • Properties of clay make it easy on players’ joints
  • Slow bounces allow more time for shot returning
  • Fun playing surface that even allows for sliding


  • Weather can cause bounce results to vary
  • Courts tend to be slippery, which can make it difficult to change direction
  • Slow bounces put heavy shot makers and big servers at a disadvantage
  • Typically require a high level of maintenance to preserve a smooth playing surface


grass tennis court

Grass courts are the original type of tennis courts; however, there are not many remaining due to the difficulty of maintaining these courts. Yet, despite the limited number of courts, many professional tournaments still use grass courts, including Wimbledon. Bounces on grass tend to be quicker and lower to the ground, giving the advantage to harder hitting players. Bounces are generally very consistent on this surface.


  • Most visually appealing court type
  • Original tennis court surface with a long history
  • Consistent bounce
  • Bounces are generally fast and low, giving the advantage to hard hitters and big servers


  • Easily worn down and require a lot of maintenance to keep at peak condition
  • Difficult to find
  • Fast and low bounces put shot returners at a disadvantage
  • Can be slippery when wet

Hard Courts (Asphalt)

hard tennis court

Hard courts are the most common type of tennis court today and are used in the most professional tournaments worldwide. Hard courts are typically made from an asphalt or concrete base, covered with an acrylic top, and mixed with other materials to produce the final product. These courts usually feature fast bounces, but bounce height can vary depending on the type of hard court, so players should be familiar with how each hard court plays to receive the best results.


  • Most commonly found type of tennis court
  • Bounces are generally fast, giving heavy shot makers and big servers the advantage
  • Courts will dry quickly after rainfall
  • Properties of hard courts make it easy to change direction and prevents slipping


  • Tougher on joints compared to other surfaces
  • Fast bounces require faster reaction times and makes returns difficult
  • Bounce height can vary depending on the exact type of hard court


carpet tennis court

Carpet courts are typically used in indoor settings, making them a great court option for tennis players looking to play during the winter. However, carpet courts are not very popular in the professional world as they are not used in any major tournaments. Carpet courts actually play the fastest out of all courts, with quicker and lower bounces than grass and hard courts.


  • Great for play during the winter as they are typically indoors
  • Much less expensive than grass courts and do not need much maintenance
  • Feature fast and low bounces, which give an advantage to big shot makers and servers


  • Low popularity
  • Play can be difficult on the knees due to low bounces
  • Bounces make it difficult for shot returning
  • Falling on this court surface will be more painful than most other surfaces

Court Markings

The tennis court features a multitude of court markings, each serving various purposes ranging from out-of-bounds markings to starting positions.

  • Baseline: The baselines are the lines on the back of the court parallel with the net. These lines span the full 36 feet in width and serve as the starting point for serves, and the boundary for long shots hit out of bounds.
  • Sidelines: There are two sets of sidelines on each side of the court that run perpendicular to the net. The first set lies on the very far sides of the court and is the boundary for wayward shots hit out of bounds for doubles. The second set lies 9 feet closer to the middle of the court on each side, setting a smaller boundary for wayward shots hit out of bounds for singles.
  • Service Box: There are four service boxes, beginning on the inner sidelines by the net, stretching halfway to the baseline and halfway across, creating a total of four rectangular shape boxes around the center of the court. Each serve must be hit into the service box on the other side of the court diagonally from where the serve occurred.


As mentioned, hard courts play differently depending on the individual hard court itself. This is because many different courts feature different brands of hard court material.


DecoTurf uses a five-layer system to create its version of hard court, beginning with an asphalt or concrete layer, followed by layers of acrylic, sand, rubber, and paint. DecoTurf prides itself on its ability to be low-maintenance, as well as its ability to withstand most weather conditions. DecoTurf is used in many tournaments, including the Olympics and the US Open until 2020.


GreenSet is another popular type of hard court that uses a similar system but features its acrylic layer on top of an asphalt or concrete base more so than other types of hard court. GreenSet was first used in 1970, primarily in indoor settings, and is now used by over 600 tournaments worldwide, including the Australian Open and the Davis Cup tournament. 


Laykold is one of the most popular types of hard court and the tennis world has seen a recent massive transition to this type of hard court, including the US Open officially changing its surface from DecoTurf to Laykold in 2020. Laykold is known for being economical and environmentally friendly, as it is locally made using locally sourced ingredients to best fit the court for the local climate.


What type of tennis court is used at Wimbledon?

The oldest grand slam of the four major tournaments, Wimbledon, has used grass tennis courts throughout its rich history and still does to this date. Specifically, Wimbledon uses perennial ryegrass cut short to just eight millimeters to produce its tennis courts. As mentioned, grass courts feature consistent bounces that are generally low and fast. This is why Roger Federer is considered to be the king of Wimbledon and grass courts by many, as these bounces are a perfect fit for his playing style.

What are the dimensions of a tennis court?

A tennis court is typically 78 feet in length with a net in the middle, dissecting the court into two 39 feet long halves. There are two sets of sidelines on a tennis court, one for singles and one for doubles, with the purpose of making the court smaller in width for singles play. The result is 27 feet of width for singles and 36 feet of width for doubles. The net stands 42 inches tall on its ends and gradually decreases to 36 inches in the middle.

What are the most common tennis court surfaces?

Today’s most commonly found tennis courts are hard courts, as this surface type is used throughout the world for many tennis tournaments and is also used recreationally in parks and rec centers. In the past, grass used to be the most popular type of tennis court surface; however, with the evolution of hard courts and the amount of maintenance needed for grass courts, this type of court has quickly fallen to the rarest type of surface.
