Whether you are building a new tennis court, resurfacing an existing one, or considering a conversion to pickleball, it all starts with understanding the dimensions. Tennis courts are larger than most people realize — and the total space you need goes well beyond the playing lines. Here is a complete breakdown of official tennis court measurements, space requirements, and everything that affects layout planning.
What are the official tennis court dimensions?
The International Tennis Federation (ITF) sets the official court dimensions used at every level of play, from your local rec center to the US Open. Here are the key measurements.
78' x 36'
Doubles Court
2,808 sq ft playing area
78' x 27'
Singles Court
2,106 sq ft playing area
21' x 13.5'
Service Box
4 boxes total (2 per side)
3 feet at the center, 3 feet 6 inches at the net posts. Posts are positioned 3 feet outside the doubles sideline on each side.
All lines are part of the court — a ball landing on any line is considered in. Baselines are 2 inches wide; all other lines are 1–2 inches wide. The center service line divides each service area into two equal boxes.
The 4.5-foot alleys on each side are the difference between singles (27’) and doubles (36’) width. Most courts are built to doubles dimensions even if primarily used for singles.
Key Takeaway
Almost all tennis courts are built to doubles dimensions (78’ x 36’) regardless of primary use. The singles lines are simply marked within the doubles court, so you always have the option for both formats.
How much total space do you need for a tennis court?
The playing area is 78’ x 36’, but you cannot just pave a 78-by-36-foot slab and call it a court. Players need room to run behind the baseline and beside the sidelines. These “overruns” are critical for safe, competitive play.
120' x 60'
USTA Recommended
7,200 sq ft total area
110' x 56'
Recreational Minimum
6,160 sq ft (tight but playable)
21' + 12'
Overrun Space
21’ behind baselines, 12’ on sides
The USTA minimum of 120’ x 60’ gives you 21 feet behind each baseline and 12 feet on each side. This is comfortable for competitive play and meets tournament standards. For a backyard or recreational court, 110’ x 56’ can work — you are trading some run-out space for a smaller footprint, which is a reasonable tradeoff if your property cannot accommodate the full USTA spec.
For comparison, a regulation pickleball court only needs 30’ x 60’ total area — about one-quarter the space of a tennis court. If space is tight, a pickleball court may be the better option. See our backyard pickleball court guide for details.
Can you convert a tennis court to pickleball?
Yes — and it is one of the most popular conversions we do. A standard 60’ x 120’ tennis court area can accommodate up to 4 pickleball courts, making it one of the most efficient sport court conversions available.
4-Court Layout
The full tennis court footprint (60’ x 120’) divides cleanly into four 30’ x 60’ pickleball courts. This is the standard conversion for parks, HOAs, and recreation centers that want to maximize court count.
2-Court Layout
If the existing surface has damage in certain areas, or you want more generous spacing between courts, a 2-court layout works well. This gives each court extra overrun room and is common for residential conversions.
Typical tennis-to-pickleball conversion cost
Per pickleball court: $7,000 – $10,000
Full 4-court conversion: $28,000 – $40,000
Includes: surface prep, crack repair, acrylic resurfacing, new line striping, and net post installation
The conversion keeps the existing concrete slab and applies a fresh acrylic surface system with new pickleball lines. If the existing surface is still in good shape, you can also add pickleball lines alongside the tennis lines for a dual-use court. For a complete walkthrough, see our pickleball court conversion guide.
Tennis court surface types and how they affect play
There are four main tennis court surface types. Each plays differently and has different maintenance requirements. Pro Court Surfaces specializes in acrylic hard court systems — the most common and practical option for Texas courts.
Acrylic Hard Court
Most CommonMulti-coat acrylic surface applied over concrete. This is the surface used at the US Open and Australian Open. It provides a fast, consistent ball bounce, excellent durability, and low maintenance. Custom color combinations are standard.
- ATS Acrytech — Our primary system. PPA-approved, multi-coat acrylic built for high-traffic courts.
- Laykold — Premium system used on professional venues worldwide. Excellent durability and color retention.
- SportMaster — Widely available acrylic system at a more accessible price point. Solid choice for residential courts.
Clay
Slower ball speed, higher bounce. The surface of the French Open. Requires significant daily maintenance — watering, rolling, and line sweeping. Not practical for most Texas residential courts due to maintenance demands and water usage.
Grass
Fast, low bounce. Used at Wimbledon. Extremely high maintenance and not viable in the Texas climate. You will not find grass tennis courts outside of elite clubs in cooler, wetter regions.
Synthetic Turf
Artificial grass infilled with sand. Low maintenance and plays similar to clay but without the watering. Used at some clubs but far less common than hard court or clay for dedicated tennis facilities.
For most residential and commercial courts in Central Texas, acrylic hard court is the right choice. It handles the heat, requires minimal maintenance, and lasts 8–10 years between resurfacings. For a deeper comparison, see our court surface types guide.
Concrete slab requirements for a tennis court
The concrete slab is the foundation of your court. Tennis courts are significantly larger than pickleball courts, which makes slab quality even more critical. Here are the key specs.
Minimum Specifications
- Thickness: 4 inches minimum
- Compressive strength: 3,500 PSI recommended
- Finish: Steel-trowel or medium broom
- Slope: 1% grade in one direction for drainage
Why 3,500 PSI?
A tennis court slab at 120’ x 60’ is 7,200 square feet of concrete. That is roughly 89 cubic yards. The larger surface area creates more thermal expansion and contraction, which means higher PSI and proper jointing are essential to prevent cracking.
Expansion Joints Matter
On a 120-foot slab, expansion joints are critical. They should be placed at the perimeter and at strategic intervals — but never through the playing surface where they would affect ball bounce. Your concrete contractor should plan joint placement before the pour.

Court orientation and fencing
Court placement on your property matters more than most people think. Orientation and fencing affect playability, safety, and long-term satisfaction.
Orientation
The USTA recommends a north-south orientation for the long axis of the court. This minimizes sun glare for players serving and returning, especially during morning and evening play. If north-south is not possible due to lot shape, a slight deviation (up to 22 degrees) is acceptable.
Fencing
Tennis court fencing is typically 10 feet high on the ends (behind baselines) and can be 8–10 feet on the sides. Chain-link is standard; vinyl-coated chain-link in black or green is the upgrade most homeowners choose. Wind screens can be added for privacy and wind reduction.
Lighting
For evening play, a single tennis court typically requires 4 light poles; a two-court complex needs 6–8 poles. LED court lighting has become the standard, offering better light distribution and lower energy costs than older halide systems.
Note: Pro Court Surfaces handles surfacing and resurfacing only. We do not install fencing or lighting, but we can recommend contractors in the Austin area for those phases of your project.
When does a tennis court need resurfacing?
Even the best acrylic surface does not last forever. Texas heat, UV exposure, and regular play all take their toll. Here are the signs that your tennis court needs attention.
Signs It Is Time
- Fading color — The surface looks washed out or uneven in color
- Surface cracking — Hairline cracks or larger structural cracks appearing
- Puddles forming — Water not draining properly after rain
- Paint peeling — Acrylic coating flaking or lifting from the slab
Typical Timeline
Most tennis courts need resurfacing every 4–8 years. The range depends on usage volume, surface quality, and local climate. In Austin and Central Texas, the combination of intense summer heat and UV exposure accelerates wear — courts here often need resurfacing closer to the 4–5 year mark compared to cooler climates.
Catching issues early saves money. A simple resurface (new color coats over a structurally sound slab) costs far less than full crack repair and rebuilding. Regular cleaning also extends surface life — see our court maintenance guide for a schedule.

Tennis court dimension FAQs
Common questions about tennis court dimensions, sizing, and construction.
What are official tennis court dimensions?
A doubles tennis court is 78 feet long by 36 feet wide (2,808 sq ft). A singles court uses the same length but is narrower at 27 feet wide (2,106 sq ft). These dimensions are set by the ITF and used at every level from recreational to professional.
How much space do you need for a backyard tennis court?
The USTA recommends a minimum total area of 120 feet by 60 feet (7,200 sq ft) to allow for proper overruns. That means 21 feet behind each baseline and 12 feet on each side. For recreational or backyard use, 110 feet by 56 feet can work but will feel tight.
How high is a tennis net?
A regulation tennis net is 3 feet (36 inches) high at the center and 3 feet 6 inches (42 inches) at the net posts. The net posts are positioned 3 feet outside the doubles sideline on each side.
How many pickleball courts fit on a tennis court?
A standard 60-foot by 120-foot tennis court area can fit 4 pickleball courts (each 30' x 60'). If the surface is compromised or you want more comfortable spacing, 2 pickleball courts is a practical alternative.
What is the best surface for a tennis court?
Acrylic hard court surfaces are the most common and lowest-maintenance option. They provide consistent ball bounce, excellent durability, and can be customized with any color combination. Pro Court Surfaces installs ATS Acrytech, Laykold, and SportMaster systems.
How thick should a tennis court concrete slab be?
A tennis court slab should be a minimum of 4 inches thick with a compressive strength of 3,500 PSI. The larger surface area of a tennis court makes proper expansion joints especially important to prevent cracking over time.
How often should a tennis court be resurfaced?
Most tennis courts need resurfacing every 4 to 8 years depending on usage, climate, and surface quality. In hot climates like Central Texas, sun exposure and heat accelerate wear, often requiring resurfacing closer to the 4-5 year mark.
Which direction should a tennis court face?
A tennis court should be oriented north-south to minimize sun glare during morning and evening play. This is the standard USTA recommendation and applies to both residential and commercial installations.
