 The Tennis Court Markings 


The baseline is the end line that runs parallel to the net and defines each side’s furthest sideline or back of the court. That’s where you’ll do most of your basic shots (forehand and back serve) and is the approximate location where you’ll return serve. Any image should not go beyond the baseline.

 Center Mark

The center mark bisects the baseline and runs perpendicular to the grid. It determines the point you cannot pass when hitting a serve in the court and ad court. 

The ad court is the left court of each player. The reason is called “ad” (advantage) because after the “advantage” is won after the score is even (deuce, 40-40), the athlete will continue to serve from the left side of the field.

 Service Line 

The service line runs parallel to the net and marks the halfway point between the net and the end line. It also marks the end of service boxes. But, different from the baseline, it only extends to single borders. Any serve beyond this line on the court will be disqualified.

 Doubles Sidelines 

A few feet outside the single line is the double line. These lines run perpendicular to the net and define the side boundaries of the field for doubles matches. The double line is also 39 feet long.

Tennis Court Surroundings

The tennis court is surrounded by a swingarm measuring 150mm wide x 250mm high. When constructing the concrete foundation for the yard, it needs to be poured with an average thickness of 10-15cm with an iron and steel structure. After pouring, cutting the anti-cracking grout for the floor surface is necessary.

The light bulb used in the yard is a 1000W dedicated high-voltage bulb. Each yard has about 8 light poles divided equally by 2 vertical borders to ensure brightness when playing at night. The lamp post is 5m high, and the ball linked to the manual pole is about 1.7m long.

The fence is built according to standards from 4.2 to 4.5m so that the ball does not fly out to ask the yard when playing the ball. The surrounding is covered with B40 mesh with a 3.5mm thread size. Each 5 cm cell is welded to the column to ensure tightness to avoid injury when accidentally bumping into the net.


 How Much Space Do You Need For A Tennis Court? 

The minimum amount of space depends on whether the field is used for competition or recreation. The recommended tennis court size length for recreational use is 114 ft/34.8 m, and the minimum width is 56 ft/17.1m. It creates a total of 595.1 square meters.

 Are Tennis Courts All The Same Size?

The dimensions of the tennis court are uniform. Even though there might be a few minor variations across the courts. ITF and ATP professional courts need to be the same. 

However, if a court has been built specifically for Touch Tennis or recreational purposes, it can be any dimension. The size of the doubles and singles courts is roughly the same, and both doubles and singles matches are played on pitches with spatial markings.

Additionally, the tennis courts have different sizes depending on the form of competition and the participants. The size difference between the two types of singles and doubles competitions has been mentioned above. 

In terms of participants, the playground for children is smaller in size. For example, mini tennis court dimensions include a Width of 6.4 meters and a length of 18.2 meters. This dimension is used for tennis matches in smaller spaces or children’s games.

 What Is The Best Surface For A Tennis Court? 

While the dimensions of all tennis courts are the same, the variety of surfaces on which matches occur can be divided into three main categories – grass, hard, and clay.

You can choose the right court surface to play depending on your needs because there are good players on one court but not good players on the other. It is impossible to say which surface is best for a tennis court.

On grass, for example, players can be the fastest and favor serve and pass play. Besides, clay-court matches can push the human body to its limits and are usually determined by a player’s ability and endurance to outwit opponents with their hands.

The ball tends to bounce high on hard courts. All-rounders like Novak Djokovic tend to play well on hard courts due to their balanced nature.
