DIRECT ANSWER
A regulation tennis net is 3 feet (0.914 m) high at the center and 3.5 feet (1.07 m) high at the posts, under ITF Rule 1. This applies to both singles and doubles — the difference between the two formats is where the net posts are placed, not how high the net is.

1. Why the Center Is Lower Than the Posts
What it is: The net is suspended between two posts at 3.5 feet, then pulled down and held taut at the center by a white strap, which brings the middle down to exactly 3 feet.
Why it matters: This half-foot dip in the middle is deliberate, not sag from wear. It slightly favors shots hit down the center of the court over shots aimed at the sidelines — which is one reason cross-court shots are generally considered a safer, higher-percentage option than shots hit down the line.
2. Where the Net Posts Actually Go
Doubles: The center of each net post sits 3 feet outside the doubles sideline on each side.
Singles: If a dedicated singles net is used, the posts sit 3 feet outside the singles sideline instead — closer together than the doubles posts.
Why it matters: Because doubles courts are wider than singles courts, a net designed for doubles (and its posts) can't simply be reused for singles without adjustment — the posts are in the wrong place for a singles-width net to hang correctly.
3. What Singles Sticks Are For
The problem: Most public and club courts have only one set of net posts, positioned for doubles. Using that same net for a singles match would leave gaps of open space beyond each singles sideline where the net isn't properly supported.
The fix: Two portable poles, called singles sticks, are placed 3 feet outside the singles sidelines and prop the doubles net up to the correct 3.5-foot height at those points — without needing separate net posts or a separate net. The ITF rule caps singles sticks at no more than 3 inches in diameter.
4. Net Height for Junior and Adjusted Formats
What it is: Junior competition formats built around shorter, slower-paced play use lower nets to match a smaller court. The most common youth progression, often called the Red, Orange, and Green stages, uses nets and courts scaled down from the full adult size.
Why it matters: This keeps rallies within reach for younger or newer players — a full 3.5-foot net on a full-size court makes the game significantly harder to sustain a rally on, which is part of why youth pathways almost always start smaller.
5. The Other Net Specifications the Rule Covers
What it is: Beyond height, ITF Rule 1 also specifies that the net must be filled completely between the posts with no gaps, made of mesh small enough that a ball can't pass through, and topped with a white band between 2 and 2.5 inches deep.
Why it matters: These details exist so that a shot which clips the very top of the net is judged consistently at every sanctioned court in the world — the same reasoning covered on this site's let-rule explainer, since a ball touching that white band on a serve is exactly what triggers a let.
