A serve kisses the net, tumbles into the service box, and suddenly both players pause: was that a lucky ace, a fault, or a do-over? In standard tennis, it’s a let serve. The point doesn’t start, the serve doesn’t count as a fault, and the server gets to try again. Simple rule—until the score is tight, the ball barely clears the tape, and everybody wants to know exactly what happens next.
Here’s the clear version: under the standard Rules of Tennis, if a serve touches the net and otherwise lands in the correct service court, it is a let. The same service attempt is replayed. Whether it was the first serve or the second serve, the server takes that same serve again.
The rule in plain English
Rule 22 of the ITF Rules of Tennis covers the service let. It says a let is called when a served ball touches the net, strap, or band and is otherwise good. “Otherwise good” is the key phrase: the serve must still land in the correct diagonal service court, including on one of that court’s boundary lines.
So if the ball clips the net cord, drops inside the correct box, and doesn’t create some other fault, the server gets another attempt. The receiver doesn’t win a point for the net touch, and the server doesn’t lose the serve for it. Play simply resets for that delivery.
What happens to the first or second serve?
The let does not erase a previous fault. It repeats the serve that was being played when the let occurred.
- First serve clips the net and lands in: Replay the first serve.
- The server has already faulted once, then the second serve clips the net and lands in: Replay the second serve.
- The replayed serve is a fault: The normal service rules apply. On a second serve, that means a double fault and a point for the receiver.
For example, imagine the server’s first serve lands long. The umpire calls “Fault.” On the next attempt, the ball catches the net and drops into the service box. That is a let, so the player repeats the second serve—not a fresh first serve. The earlier fault still counts.
Quick guide to common net-cord serves
| What happens | Ruling |
|---|---|
| Serve touches net and lands in the correct service court | Let; replay the same serve |
| Serve touches net and lands outside the correct service court | Fault |
| Serve lands on a line that forms part of the correct service court | It is in; if it touched the net, it is a let |
| Serve hits the net and fails to reach the net | Fault |
| Serve touches net, then hits the receiver or their partner before bouncing | Let, if the serve would otherwise have been good |
What if the ball clips the net but lands out?
A net touch doesn’t give a serve a free pass. If the ball catches the tape and lands outside the correct service court, it is a fault. If it is the server’s second serve, that fault is a double fault and the receiver wins the point.
Likewise, if the ball clips the net and lands in the wrong service box, it is a fault. The serve has to be aimed into the diagonally opposite box for that side of the court. A ball landing on the service-line boundary, though, counts as in—the line belongs to the court.
That’s why the call depends on both things: Did the serve touch the net? And was it otherwise good? Net touch plus correct box means let. Net touch plus an out landing means fault.
Does the receiver have to let the ball bounce?
No. If the serve touches the net and is otherwise good, it is still a let even if the receiver reaches for it before it bounces. The receiver may instinctively block or catch a soft net-cord serve, but that doesn’t turn the let into a point. The umpire calls the let and the same serve is replayed.
The rules also account for a serve that touches the net and then hits the receiver or the receiver’s partner before touching the ground. If the serve would otherwise have been good, that is a let as well. This prevents a player from losing a point simply because a net-cord serve takes an awkward, unexpected path into them.
Who calls the let?
In a professional match, the chair umpire makes the call. You’ll usually hear “Let” promptly after the net touch, and the players reset. In a match without an umpire, players are responsible for making the call honestly and promptly, following the competition’s rules.
In casual play, it’s easy to get tangled up in the moment—especially when a serve barely brushes the net. A useful habit is to call a let only when you’re sure the serve touched the net and landed in the correct box. If it touched the net and landed out, call a fault instead. When there’s genuine uncertainty in an organized match, follow the event’s procedures rather than arguing the point into existence.
Why does the rule exist?
A serve that clips the net can drop short, kick sideways, or arrive with a strange change of pace. The let rule gives the receiver a fair chance at a normal serve instead of awarding a point—or a fault—based on an unpredictable ricochet. It also keeps the ruling consistent: the net touch itself isn’t a penalty, but the serve still has to land in the right place.
That can matter tactically. A let is a reset, not a reward or punishment. The server can take a breath and repeat the delivery, while the receiver should be ready to react again rather than celebrating a point that hasn’t been won. On a second serve, the pressure remains because the replay is still a second serve. The let doesn’t turn it into a first.
These are the standard rules used in conventional tennis. Some events or recreational formats may explicitly adopt a “no-let” rule, where a serve that touches the net and lands in remains live. If you’re playing one of those formats, check the event rules before the match; otherwise, use the standard let ruling.
Frequently Asked Questions
Does a let serve count as a fault?
No. A let is replayed and does not count as a fault. But it also does not cancel an earlier fault, so a let on a second serve is replayed as a second serve.
If the ball touches the net and lands on the service line, is it a let?
Yes, if that line is part of the correct service court. A serve landing on the boundary line is in. Since it touched the net, it is a let and the same serve is replayed.
Can a net-cord serve be an ace?
Not under the standard rules if it touches the net and is otherwise good: it is called a let and replayed, even if the receiver cannot reach it.
Is the rule different on a second serve or during a tiebreak?
The standard let ruling is the same. Replay the serve that was in progress: a first serve remains a first serve, and a second serve remains a second serve. The same principle applies during a tiebreak.
Final Thoughts
If a serve clips the net and lands in the correct service box, call “let” and replay that serve—first or second. If it clips the net and lands out, it’s a fault. That’s the whole rule, and knowing the difference can save a lot of confusion when a match gets tense. Net cord, right box, replay. Now get ready for the next serve.
