A tennis court’s painted lines take up less space than most people expect. The catch is that players need room beyond those lines to chase down a lob, reach a wide serve, and slow down safely. For a comfortable full-size court, plan on a clear, level area about 120 feet long by 60 feet wide—roughly 7,200 square feet, or 0.17 acre.
That is the practical planning figure for a single court, not the size of the playing lines alone. If you are measuring a backyard, buying land, or laying out a facility, the difference matters: a court can technically fit on a smaller footprint, but tight run-off space can make it awkward and unsafe to play.
The dimensions of a tennis court
The marked court is 78 feet long. Its width is 36 feet for doubles and 27 feet for singles. Those measurements describe the outside edges of the playing lines; they do not include the space players need to move outside the court.
| Measurement | Feet | Approx. square feet |
|---|---|---|
| Marked doubles court | 78 × 36 | 2,808 |
| Marked singles court | 78 × 27 | 2,106 |
| Common planning footprint | 120 × 60 | 7,200 |
The doubles lines set the court’s full width even if you mostly play singles. A singles match uses the narrower singles sidelines, but the extra space remains part of the court and is useful for practice and doubles play.
In metric measurements, the marked court is about 23.77 metres long and 10.97 metres wide for doubles. A 120-by-60-foot planning area is approximately 36.6 by 18.3 metres.
Why a full court needs more than 2,808 square feet
The extra area is the run-off zone: the space behind each baseline and outside each doubles sideline. Without it, a player may reach the edge of the surface just as they are trying to stop or change direction. A deep return, a defensive lob, or a wide ball can send someone several steps beyond the lines.
A common full-size planning allowance is about 21 feet behind each baseline and 12 feet beyond each doubles sideline. Added to the court’s 78-by-36-foot dimensions, that produces a 120-by-60-foot rectangle. The International Tennis Federation’s court-construction guidance uses these kinds of clearances for a comfortable layout. Exact requirements can differ by facility, competition level, and local rules, so check the relevant standard before building a club or tournament court.
A smaller clear area may work for casual family play, but it changes the experience. If there is little room behind the baseline, players have less time to handle deep shots. If the side clearance is narrow, running down a wide ball feels cramped. The court markings may be regulation size while the overall playing environment is not.
How much land should you set aside?
For one court, reserve at least a clear rectangle of roughly 120 by 60 feet if the site allows. That is the court and its immediate playing space—not necessarily the total property area you need. Fencing, gates, paths, seating, lighting poles, landscaping, and setbacks can all extend beyond that rectangle.
For example, a 100-by-70-foot backyard contains 7,000 square feet, but it is not automatically large enough. Its area is close to the 7,200-square-foot planning figure, yet it is 20 feet too short in one direction. Tennis court layouts need the right shape as well as enough total square footage.
Likewise, a 120-by-60-foot parcel may not provide 120 by 60 feet of usable court space if a house, retaining wall, utility easement, trees, or required property setbacks reduce the clear area. Measure the unobstructed ground, not just the lot boundaries. A surveyor or court contractor can help confirm the usable dimensions before you commit to excavation or materials.
Allow extra room for the site
- Fencing: A fence is usually placed around the outside of the playing area, so its posts and gates need additional space. Check whether your quoted footprint includes the fence.
- Access: Leave room for a gate, a path to the court, and equipment access. Construction vehicles may need more clearance than players do.
- Drainage and grading: The surface needs a stable base and a plan for moving water away. The surrounding ground may need grading beyond the court rectangle.
- Lighting: Light poles and their foundations can sit outside the playing area. Their placement and height may be governed by local rules.
- Neighbors and regulations: Check property setbacks, fencing limits, lighting rules, and any homeowners’ association requirements before designing the layout.
Choosing the best position on your property
When you have a choice, orient the court close to north–south. That generally reduces the chance of players looking directly into a low morning or evening sun at one end. The ideal orientation is not always possible, particularly on a sloped or irregular property, but it is worth considering early.
Look at wind and drainage, too. A court exposed to strong gusts can make a routine toss or high ball difficult to judge. A low spot that holds water may delay play and damage the surface over time. Trees can provide welcome shade, but roots may disturb the base and leaves or sap can create extra maintenance.
Think about how people will actually use the space. A court tucked behind a house may be quiet, while one close to bedrooms or neighboring patios can make evening play and lighting more sensitive. A little planning around access, privacy, and noise can save a lot of frustration later.
What if you have less space?
If 120 by 60 feet will not fit, first ask a court designer whether the available rectangle can support a smaller run-off area that still suits your intended use. Some recreational courts are built with reduced clearances, but there is no single smaller footprint that works for every site or playing level. Avoid assuming that shrinking the marked court is the best fix: it changes the game itself, while reducing the surrounding clearance affects how safely players can move.
If a full court is not practical, alternatives include a half-court or a practice area with a rebound wall. These can be useful for hitting and footwork, but they are not substitutes for a full doubles court. Be clear about the intended use before paying for a design.
Frequently Asked Questions
Is 60 by 120 feet enough for a tennis court?
It is a common planning footprint for one full-size court, including useful clearance around the marked lines. Confirm that the full rectangle is actually clear and check local requirements for fencing, lighting, and setbacks.
How many acres do you need for one tennis court?
A 120-by-60-foot court area is 7,200 square feet, or about 0.17 acre. The property may need to be larger if you also need access, landscaping, parking, setbacks, or other site features.
Can I build a tennis court in a 100-by-60-foot space?
The 78-foot court length leaves only 11 feet behind each baseline in a 100-foot space. That is less clearance than the common 120-by-60-foot layout, so it may feel restrictive and may not meet the requirements for your intended use. Ask a court professional to assess the site before proceeding.
Does a singles court need less land?
The singles sidelines make the marked playing width 27 feet rather than 36, but a full-size tennis court is generally laid out to include doubles lines and their wider playing area. The overall footprint is typically planned around the doubles court.
Final Thoughts
For a single full-size tennis court, use 120 by 60 feet, or about 7,200 square feet, as a practical starting point. The painted doubles court itself is 78 by 36 feet, but the surrounding clearance is what gives players room to move. Before building, measure the usable shape of the site and account for drainage, fencing, access, lighting, and local rules. That extra planning is what turns a court that merely fits into one that is enjoyable to play on.
