Planning a tennis court, checking a facility listing, or just curious about how much space a match uses? The answer depends on whether you mean the painted playing rectangle or the larger footprint needed around it. Those figures are quite different.
A regulation doubles court measures 78 feet long by 36 feet wide, for a playing area of 2,808 square feet. The singles lines use a narrower section of that same court. For safe play, though, players also need clear space behind the baselines and beside the sidelines.
Regulation tennis court area and dimensions
The court’s length stays the same for singles and doubles. The difference is the width: singles uses the inner sidelines, while doubles uses the outer sidelines. Measurements below are approximate metric conversions.
| Measurement | Feet | Meters | Area |
|---|---|---|---|
| Doubles court | 78 × 36 ft | 23.77 × 10.97 m | 2,808 sq ft / 260.9 sq m |
| Singles court | 78 × 27 ft | 23.77 × 8.23 m | 2,106 sq ft / 195.6 sq m |
| Doubles alley on each side | 4.5 × 78 ft | 1.37 × 23.77 m | 351 sq ft / 32.6 sq m |
The singles court is not a separate, shorter court. It is the narrower playing area inside the doubles sidelines. In doubles, the extra 4.5 feet on each side—the alleys—are in play. In singles, shots landing in those alleys are out.
How much land do you need for a tennis court?
The painted court rectangle is only part of a usable facility. Players need room to run through the baseline and sideline areas, and a fence or wall should not sit right beside the playing lines. A commonly used planning footprint is about 120 by 60 feet, or 7,200 square feet (about 669 square meters). That allows roughly 21 feet behind each baseline and 12 feet beyond each doubles sideline.
Those clearances make a practical difference. A player chasing a deep lob needs space to slow down behind the baseline; someone sprinting wide for a forehand needs room beyond the sideline. A court squeezed into a smaller space may still work for casual hitting, but it can feel cramped and create safety concerns during full-speed play. Check the requirements of your local tennis organization, facility, or building authority before construction, since standards can vary by court type and use.
For multiple courts, allow for the space between playing areas as well as the space around the outside courts. Shared fences, lighting poles, gates, walkways, and benches also need to fit without intruding into player runoffs. The land requirement is therefore larger than simply multiplying the painted court area by the number of courts.
Key court measurements beyond the overall area
The court is divided into smaller zones that shape how points are played. The service line sits 21 feet from the net on each side. A center service line divides each half of the court into two service boxes, each roughly 21 by 13.5 feet. Servers aim into the diagonally opposite box, so understanding these markings helps when practicing placement.
- Baseline: The back boundary of the court. Players serve from behind it and often recover near it during rallies.
- Singles sidelines: The inner side boundaries for singles matches.
- Doubles sidelines: The outer side boundaries, including the alleys.
- Service line: The line that marks the back of the service boxes.
- Center service line: The line separating the two service boxes on each side of the net.
The net is 3 feet high at the center and 3 feet 6 inches at the posts. That dip toward the middle gives players a little more room to hit a low shot over the center than near the sidelines. It is one reason a crosscourt rally can feel safer: the net is lower there, and the diagonal path gives the ball more distance to travel before reaching the opposite corner.
Why the court’s area matters in play
Knowing the court’s dimensions can make tactics easier to picture. A crosscourt shot travels along the longer diagonal of the court, giving a player more margin than a straight shot down the line. The doubles alleys also change court coverage: partners can divide the width between them, but a well-placed shot down the middle may cause confusion about who should take it.
For singles practice, players often use cones or target zones to work on depth and width. A ball that lands close to the baseline can push an opponent back, while a shot near the sideline can pull them off balance. The goal is not always to hit the very edge; consistent placement inside the lines is usually more valuable than risky attempts at the corners.
Surface does not change the regulation court dimensions, but it can change how much time players have to cover that space. On a slower clay court, the ball often gives players more time to reach a wide shot. On a faster surface, a short reaction window can make the same distance feel harder to cover.
Frequently Asked Questions
What is the area of a standard doubles tennis court?
The doubles playing rectangle is 78 by 36 feet, or about 2,808 square feet (260.9 square meters). This figure covers the marked court, not the surrounding runoffs.
What is the area of a singles tennis court?
The singles playing area is 78 by 27 feet, or about 2,106 square feet (195.6 square meters). It uses the inner sidelines on a regulation court.
How much space is needed to build a tennis court?
A common planning footprint is around 120 by 60 feet, or 7,200 square feet, to provide room around the playing lines. Confirm the required clearances for your location and intended level of play before building.
Do singles and doubles have different court lengths?
No. Both are 78 feet long. Doubles is wider because the outer sidelines and alleys are included in play.
Final Thoughts
A regulation tennis court covers 2,808 square feet for doubles or 2,106 square feet for singles, but those numbers describe only the playing lines. If you are assessing a property or planning a facility, allow additional room for safe movement, fencing, and access. That extra space is what makes a court comfortable to play on, not just large enough to mark.
