Whether you’re building a court, planning a facility, or just getting serious about the game — knowing the exact tennis court dimensions is essential. Wrong measurements mean wrong play.
This guide gives you a clear tennis court dimensions chart, every line explained, and practical space planning tips — all in one place.
Standard Tennis Court Dimensions — Singles and Doubles
Every professional court follows the same ITF-regulated standard size. The total length is always 78 feet (23.77 m) — for both singles and doubles. What changes is the width.
Singles and doubles courts share the same baseline. Only the side boundaries differ, defined by the doubles alleys on each side.
Singles Tennis Court Dimensions
A singles court measures 78 ft long × 27 ft wide (23.77 m × 8.23 m). The service line sits exactly 21 ft (6.4 m) from the net on both sides. Total playing area is 2,106 ft² (195.65 m²).
Doubles Tennis Court Dimensions
A doubles court measures 78 ft long × 36 ft wide (23.77 m × 10.97 m). The extra 4.5 ft (1.37 m) on each side forms the doubles alley. Total playing area reaches 2,808 ft² (260.87 m²).
| Court Measurement | Feet | Meters |
|---|---|---|
| Overall Length | 78 ft | 23.77 m |
| Singles Width | 27 ft | 8.23 m |
| Doubles Width | 36 ft | 10.97 m |
| Service Line Distance (from net) | 21 ft | 6.40 m |
| Doubles Alley Width (each side) | 4.5 ft | 1.37 m |
| Net Height — Center | 3 ft | 0.91 m |
| Net Height — Posts | 3 ft 6 in | 1.07 m |
| Net Post Placement (outside court) | 3 ft | 0.91 m |
| Baseline Width (line thickness) | min. 4 in | min. 10 cm |
| Other Line Width | min. 2 in | min. 5 cm |
| Minimum Total Space (with clearance) | 120 × 60 ft | 36.58 × 18.29 m |
| Total Area with Clearance | 7,200 ft² | 668.9 m² |
| Tournament Court Total Space | 130 × 70 ft | 39.62 × 21.34 m |
Tennis Court Markings and Lines Explained
Every line on a regulation tennis court has a specific purpose. Understanding the court markings improves both play and planning.
The baseline runs along the back of the court. The center mark divides it in half, defining where you serve from.
Service Boxes, Baselines, and Doubles Alleys
The deuce service box is on the right side of the court — you always start serving here. The ad service box is on the left, used when the score reaches advantage.
“No man’s land” is the informal name for the large mid-court zone between the service line and baseline. It’s the hardest area to hold your ground in. Doubles alleys are only in play during doubles matches — in singles, balls landing there are out.
Net Height and Post Dimensions
The tennis net is not flat across its width — it sags slightly in the center by design. At the net posts, it stands 3 ft 6 in (1.07 m) tall. At the center strap, it drops to exactly 3 ft (0.91 m).
Net posts are placed 3 ft (0.91 m) outside the doubles sideline. This keeps the net taut and properly angled across the full court width of 42 ft (12.8 m).
How Much Space Do You Need for a Tennis Court?
Fitting a full tennis court takes more land than most people expect. The playing surface alone isn’t enough — you need safe run-back and side clearance around it.
A standard recreational court requires a minimum footprint of 120 ft × 60 ft (36.58 m × 18.29 m) — that’s roughly 7,200 ft² (668.9 m²). For a tournament-grade court with full player overrun and umpire access, plan for 130 ft × 70 ft (39.62 m × 21.34 m), totaling around 9,100 ft² (845 m²).
Hard courts (asphalt or concrete with acrylic surfacing) are the most popular and cost-effective choice across the USA. They need far less maintenance than clay or grass courts and perform consistently across all weather conditions. According to the USTA, hard courts are the most widely used court surface type in American facilities.
Conclusion
Understanding the tennis court dimensions chart is the foundation — whether you’re playing, coaching, or building. Every measurement has a purpose, and every line tells you exactly where the game is won or lost.
Use this guide as your go-to court dimensions reference — from the baseline to the net, from singles to doubles, in feet and meters.
