A tennis court looks compact when you’re standing behind the baseline, but the painted lines tell only part of the story. Players need room to run through shots, serve without feeling boxed in, and move safely around the court. For a typical full-size court, plan on a space about 120 feet long by 60 feet wide—not just the smaller area inside the lines.
The court dimensions and the space around it
The playing dimensions are set by the rules. A court is 78 feet long. It is 27 feet wide for singles and 36 feet wide for doubles, including the doubles alleys. The net divides the court in half, but both singles and doubles use the same 78-foot length.
| Area | Dimensions | Approximate area |
|---|---|---|
| Singles playing area | 78 × 27 feet | 2,106 square feet |
| Doubles playing area | 78 × 36 feet | 2,808 square feet |
| Common full court footprint, including run-off space | 120 × 60 feet | 7,200 square feet |
The 120-by-60-foot footprint is about 36.6 by 18.3 metres, or roughly 0.165 acre. It leaves 21 feet behind each baseline and 12 feet beyond each doubles sideline. Those margins are what turn a regulation playing rectangle into a usable court.
For a singles-only setup, the sidelines are narrower, but it is usually still sensible to keep the full doubles-width footprint. The extra width gives players room to move and keeps the court adaptable for doubles, lessons, and casual play.
Why the run-off space matters
A player does not stop at the baseline when chasing a deep ball. They may sprint backward, plant, and hit while moving, or need several steps to slow down. The space behind the baseline also matters on a serve: a player needs room to stand and move through the motion without crowding a fence or wall.
The same goes for the sides. A wide serve or a sharply angled shot can pull a player toward the doubles alley and beyond it. With too little clearance, players shorten their steps or avoid going all-out. That affects both safety and the quality of play.
As a practical guide, the 120-by-60-foot layout is a comfortable target for a private or community court. A tighter layout may be possible for informal play, but it leaves less room to chase balls. Before building, check local codes and the requirements of your governing body or facility. Competition venues may need more clearance than a home court.
How much land should you set aside?
Start with a rectangle of at least 120 by 60 feet for the court and its playing clearances. That is 7,200 square feet, but it is not necessarily the full property area you should reserve. Fences, gates, access paths, drainage, lighting poles, and landscaping can all extend beyond the playing footprint.
If you are planning a backyard court, allow extra room around the fence where the site permits. You may also want space for a bench, a ball basket, or a safe route from the house to the court. A nominal 120-by-60-foot space that has a fence, retaining wall, or shrubs tight to its edges can feel cramped and may create maintenance problems.
Measure the usable ground, not just the lot on a plan. Slopes, trees, utility easements, and underground services can make a seemingly large area unsuitable. A court surface also needs a stable base and appropriate drainage; water should not collect where players run or stand.
Planning an indoor court or multiple courts
An indoor court needs the same floor dimensions and run-off space, plus room above the playing area. Low ceilings can interfere with lobs and overhead shots, so check the clear height requirements for the level of play you expect. Account for lights, beams, ducts, and other objects that hang below the roof structure.
For two side-by-side courts, do not simply double the 60-foot width and assume the middle boundary is harmless. Each court needs its own sideline clearance, and the space between courts should be planned so players, officials, and equipment do not create hazards. A 120-by-120-foot rectangle is a useful early planning figure for two courts with the common 60-foot court envelopes placed side by side, but a facility designer should confirm the final layout and circulation routes.
Outdoor courts are generally oriented north to south when the site allows. That helps reduce the times when players are looking directly into low morning or evening sun. Orientation does not change the dimensions, but it can make a court much more pleasant to use.
Measure before you commit
Before ordering materials or hiring a contractor, mark out the proposed footprint with string, stakes, or a tape measure. Include the full 120-by-60-foot area, not only the painted lines. Walk the baselines and sidelines as if you were chasing a ball. Check where gates, fences, trees, and neighboring property lines fall.
Also decide whether the court needs to support singles only, regular doubles, coaching, or organized matches. A family court may be used casually and tolerate tighter margins; a club court that hosts matches should follow the relevant facility standards. Confirm local planning rules, setbacks, lighting restrictions, and drainage requirements before construction begins.
Frequently Asked Questions
What is the minimum space for a tennis court?
The playing lines alone cover 78 by 36 feet for doubles, but that is not a practical full-court site because there is no room to run outside them. A common planning footprint is 120 by 60 feet. Any smaller layout should be checked against the intended use and applicable facility standards.
How many square feet is a tennis court?
The doubles playing area is 2,808 square feet, while the singles area between its sidelines is 2,106 square feet. Including typical run-off space, a full court footprint of 120 by 60 feet is 7,200 square feet.
Can I build a tennis court for singles only?
Yes. Singles uses a 27-foot playing width rather than the 36-foot doubles width. However, keeping the wider overall footprint is often worthwhile: it gives players more clearance and lets you use the court for doubles later.
Does the 120-by-60-foot measurement include the fence?
It describes a commonly used court-and-clearance footprint, not necessarily the full land needed for every fence system or site. Fence posts, access gates, paths, and landscaping may require additional room. Confirm the actual outside dimensions with your contractor before setting property boundaries.
Final Thoughts
For a comfortable full-size tennis court, plan around 120 feet by 60 feet, or 7,200 square feet, rather than measuring only the lines. The playing rectangle is 78 feet long and 36 feet wide for doubles, but the surrounding clearance is what lets players serve, chase, and recover safely. Leave extra room for fences and site features, and check local requirements before construction.
