The numbers that actually matter

Almost every tennis court question comes down to three numbers. The court is 78 feet long, full stop — singles and doubles play on the same length. The width changes: 36 feet for doubles, 27 feet for singles, with the 4½-foot alleys making up the difference. And the service line sits 21 feet from the net, which fixes the size of all four service boxes at 13½ × 21 feet.

The number people forget is the space around the court. A court that measures correctly but sits four feet from a fence is unplayable. Allow roughly 21 feet of run-back behind each baseline and about 12 feet at the sides — which is how a 78 × 36 ft court becomes a 60 × 120 ft fenced footprint.

What are the dimensions of a tennis court?
A regulation tennis court is 78 feet long. It is 36 feet wide for doubles and 27 feet wide for singles — the difference is the two 4.5-foot doubles alleys down each side. The service lines sit 21 feet from the net on each side, making four service boxes of 13.5 × 21 feet. From net to baseline is 39 feet. In metric that is 23.77 m long by 10.97 m (doubles) or 8.23 m (singles) wide.
How high is a tennis net?
3 feet 6 inches (42 inches) at the posts and 3 feet (36 inches) at the centre, where it is held down by the centre strap. The posts stand 3 feet outside each doubles sideline, which puts their centres 42 feet apart. Those measurements are printed on the full-court sheets.
What are the junior 60 ft and 36 ft tennis court dimensions?
The ITF and USTA 10-and-Under progression uses two smaller courts. The Orange court is 60 × 27 feet (21 feet wide for singles) with the service line 18 feet from a 36-inch net, for roughly ages 7 to 10. The Red court is 36 × 18 feet with a 33-inch net, for roughly ages 4 to 8, and is usually set up sideways across a full court. Both have their own measured sheet above.
How much space do you need to build a tennis court?
More than the court itself. The playing surface is 78 × 36 feet, but you need run-back behind each baseline and room at the sides. The common recommendation for a single fenced court is about 60 × 120 feet, with a minimum of roughly 21 feet of run-back behind each baseline. If you are planning a backyard court, measure the total fenced footprint rather than the lines.
How does a tennis court compare to a pickleball court?
A pickleball court is 20 × 44 feet, roughly a quarter the area of a 36 × 78 ft tennis court. That size difference is why one tennis court commonly converts into four pickleball courts, and why blended pickleball lines are often taped onto an existing tennis surface.
