These tennis court dimensions remain identical across professional Grand Slam venues, community courts, schools, sports academies, and residential installations.

Tennis Court Size in Meters

One of the most searched questions is:

What is the size of a tennis court in meters?

The official size of a tennis court in meters is:

• Length: 23.77 meters
• Singles Width: 8.23 meters
• Doubles Width: 10.97 meters

Although the doubles court is wider than the singles court, both formats use the same court length.

When constructing a new court, additional clearance around the playing area is recommended for safe movement and tournament compliance. This extra space accommodates player run-off, umpire chairs, fencing, and maintenance access.

Tennis Court Measurement in Feet

In countries like the United States and parts of Asia, dimensions are often referenced in imperial units. Understanding the tennis court measurement in feet is especially useful when reading construction plans or purchasing sports flooring materials.

Here are the standard measurements:

• Court Length – 78 feet
• Singles Court Width – 27 feet
• Doubles Court Width – 36 feet
• Distance from Baseline to Net – 39 feet
• Service Line Distance – 21 feet
• Net Height at Center – 3 feet
• Net Height at Posts – 3 feet 6 inches

Whether you work in metric or imperial units, both systems represent the same official specifications.

Tennis Court Layout Explained

Understanding the tennis court layout is just as important as knowing the dimensions. Each section of the court serves a specific purpose during play.

A standard tennis court consists of:

Baselines

Located at each end of the court, the baselines define the rear boundary. Players typically serve from behind the baseline and often rally close to it during baseline exchanges.

Singles Sidelines

These mark the playable width for singles matches.

Doubles Sidelines

The outer sidelines expand the court width for doubles matches, allowing four players to compete with additional lateral space.

Service Boxes

The area between the service line and the net is divided into four service boxes by the center service line. A legal serve must land diagonally in the opponent’s service box.

Center Service Line

This line divides the service area into left and right service courts.

Center Mark

A short mark at the center of each baseline helps players position themselves correctly while serving.

Every line plays an essential role in maintaining fair play and accurate officiating.

Singles vs Doubles Tennis Court Dimensions

Although both formats share the same court length, the width changes depending on the type of match being played.

Feature	Singles	Doubles
Length	23.77 m (78 ft)	23.77 m (78 ft)
Width	8.23 m (27 ft)	10.97 m (36 ft)
Alley Width	Not Used	1.37 m (4.5 ft) Each Side

The additional space in doubles comes from the doubles alleys located on either side of the singles court.

These alleys increase the court width by approximately 2.74 meters (9 feet) overall.

Tennis Court Lines and Their Measurements

Accurate line markings are essential for gameplay and officiating. They determine whether a ball is in or out and guide player positioning throughout the match.

Baseline

• Width: Up to 10 cm (4 inches)
• Located at each end of the court

Sidelines

• Singles Sideline
• Doubles Sideline

These define the court boundaries depending on the format being played.

Service Line

Positioned:

• 6.40 meters (21 feet) from the net

This creates the service boxes used during serves.

Center Service Line

Runs perpendicular from the net to the service line and divides the service courts equally.

Center Mark

A short line measuring approximately 10 cm (4 inches) extends from the baseline toward the net, helping players align correctly before serving.

Proper line marking is especially important when using acrylic or synthetic sports flooring, as high-quality coatings improve visibility and durability.

Tennis Net Height and Pole Placement

The tennis net is one of the most important components of the court and must meet official standards.

Official Net Height

Location	Height
Center	0.914 meters (3 feet)
Net Posts	1.07 meters (3 feet 6 inches)

The center strap keeps the net lower in the middle, ensuring consistent gameplay.

Pole Placement

• Singles matches may use singles sticks when playing on a doubles court.
• Net posts are positioned just outside the doubles sidelines.
• Proper post installation ensures the net remains correctly tensioned throughout play.

Key Takeaways

Understanding tennis court measurements is the foundation of proper court design and construction. Whether you’re measuring a recreational court or planning a professional facility, following the official tennis court dimensions ensures accurate gameplay, compliance with ITF standards, and long-term performance.

In this first part, we’ve covered:

• Official tennis court dimensions
• Tennis court size in meters and feet
• Complete tennis court layout
• Singles and doubles court measurements
• Line markings and their purpose
• Official net height and pole placement

In the next part, we’ll explore the total land area required for a tennis court, run-off space, dimensions of lawn tennis court, ITF construction guidelines, common measurement mistakes, FAQs, and expert tips for building a professional tennis court.

Total Space Required for a Tennis Court

While the official playing area measures 23.77 × 10.97 meters (78 × 36 feet) for doubles, this isn’t the total land required to build a tennis court. Players need additional space around the court to move safely, retrieve balls, and avoid collisions with fences or walls.

Recommended Total Tennis Court Area

Court Type	Total Size (Meters)	Total Size (Feet)
Recreational Court	34.75 × 17.07 m	114 × 56 ft
Club & Tournament Court	36.58 × 18.29 m	120 × 60 ft

This additional area is known as the run-off area or clearance zone and is an essential part of professional court construction.

Recommended Run-Off Space

• Behind each baseline: 6.40 meters (21 feet)
• Along each sideline: 3.66 meters (12 feet)

Adequate run-off space improves player safety and allows uninterrupted movement during fast-paced rallies.

Dimensions of Lawn Tennis Court

The dimensions of a lawn tennis court are exactly the same as those of any other standard tennis court. Whether the surface is natural grass, acrylic, clay, synthetic turf, or cushioned hard court, the playing dimensions remain unchanged.

Official Dimensions of Lawn Tennis Court

Measurement	Meters	Feet
Length	23.77 m	78 ft
Singles Width	8.23 m	27 ft
Doubles Width	10.97 m	36 ft
Net Height (Center)	0.914 m	3 ft

The primary difference lies in the playing surface rather than the dimensions. Grass courts offer faster ball speed and lower bounce, while acrylic hard courts provide consistent bounce with lower maintenance.

ITF Official Standards for Tennis Courts

The International Tennis Federation (ITF) establishes the standards used for tennis courts worldwide. Following these guidelines ensures that courts are suitable for recreational play, coaching, national competitions, and international tournaments.

Key ITF requirements include:

• Court Length: 23.77 meters (78 feet)
• Singles Width: 8.23 meters (27 feet)
