A serve that catches the net can look like a mistake, but it may not cost the server a point. If the ball still lands in the correct service box, play stops and the serve is replayed. That stoppage is called a tennis let.
Knowing when a let applies—and when it does not—helps players handle close calls fairly. The key difference is whether the ball touched the net on a serve or during a rally: the rules treat those situations differently.
What Is a Let in Tennis?
A let is a call that stops play and requires a point, or part of a point, to be replayed. The most familiar example is a serve that clips the net cord and lands in the correct service box. The serve is replayed because the net contact may have changed the ball’s path.
On a let serve, the server gets another attempt at the same serve. If it happens on a first serve, the player serves another first serve. If it happens on a second serve, the player gets another second serve—not a new first serve.
There is no limit to the number of lets a player can have. If several serves in a row touch the net and land in, each one is replayed.
When Is a Serve Called a Let?
A serve is a let when it touches the net, strap, or band and then lands in the correct service box. The ball must still land in the box diagonally opposite the server. Touching the net alone does not make a serve a let; where the ball lands matters.
- Net touch, then in the correct box: Let. Replay the serve.
- Net touch, then outside the correct box: Fault.
- No net touch, but the serve lands out: Fault.
- Let on a second serve: Replay the second serve.
For example, if a player’s first serve grazes the net and drops into the correct box, the umpire calls “Let” and the player serves again. If the ball catches the net but bounces beyond the service line or wide of the box, it is a fault instead.
Other Reasons a Let May Be Called
A let can also be called if something outside the point disrupts play. The exact decision depends on the situation and the rules being used, but the general idea is that play should be stopped when a genuine interruption makes it unfair to continue.
- The receiver is not ready: A receiver who is not ready may signal before the serve. If they make an attempt to return it, they generally cannot then claim they were unprepared.
- A stray ball enters the court: If a ball from another court creates a real safety risk or distracts a player, play may be stopped.
- An outside interruption occurs: A sudden disturbance may lead to a let if it interferes with the point.
In a match with a chair umpire, the official makes the call. In a casual match without an umpire, players should stop if there is a clear interruption and agree to replay the point. If there is uncertainty, calm discussion is better than trying to claim a point after play has stopped.
Does a Ball That Hits the Net During a Rally Count as a Let?
Usually, no. Once a rally is underway, a ball that hits the net and lands inside the opponent’s court is still in play. The opponent must try to return it just as they would any other shot.
This is different from a serve. A serve that touches the net and lands in the service box is replayed, while a rally shot that clips the net and lands in is live. If the rally ball hits the net and then lands out, the player who hit it loses the point.
For instance, a topspin forehand might catch the net and tumble over, leaving the opponent little time to react. It may be an awkward or lucky shot, but it counts if it lands in. Players should keep moving until the ball bounces out or the point is otherwise over.
Let vs. Fault: What’s the Difference?
| Situation | Call | What happens next? |
|---|---|---|
| Serve touches the net and lands in the correct service box | Let | Replay the same serve attempt |
| Serve touches the net and lands outside the correct service box | Fault | Count it as a fault |
| Serve misses the service box without touching the net | Fault | Count it as a fault |
| Rally shot touches the net and lands in | Ball is in play | Continue the point |
A fault counts toward the server’s two allowed attempts. Two faults in a row result in a double fault, and the receiver wins the point. A let does not count as a fault, so it does not use up an attempt.
How a Let Affects Players Tactically
A let can interrupt a server’s rhythm or give them another chance after a serve that would otherwise have been successful. The replay may feel especially important on a second serve, when a fault would hand the opponent a chance to attack. Still, a server should treat a let as a reset rather than a bonus point: the next serve must land in the box without relying on the net.
For the receiver, the practical response is simple. Stay ready until the umpire calls the let or the ball is clearly out. A net-cord serve can change direction and drop short, so moving too early can make the next shot harder. In friendly matches, calling a clear let promptly keeps both players safe and avoids arguments.
Frequently Asked Questions
Does a let count as a fault?
No. A let does not count as a fault, and the same serve attempt is replayed. A let on a second serve means the player serves another second serve.
Can a player have more than one let in a row?
Yes. There is no limit to the number of lets. Each serve that touches the net and lands in the correct service box is replayed.
Is a ball that hits the net and lands in always a let?
No. It is a let when it happens on a serve and the ball lands in the correct service box. During a rally, a ball that touches the net and lands in is still live.
Can the receiver call a let?
In an officiated match, the chair umpire makes the call. In a match without an umpire, players can stop play for a clear interruption and agree to replay it. A receiver who attempts to return a serve generally cannot then claim they were not ready.
Final Thoughts
The simplest rule to remember is this: a serve that clips the net and lands in the correct service box is replayed, but a rally ball that clips the net and lands in stays live. A let is not a fault, and it does not cost the server an attempt. Keep playing until the call is made, and use the same rule consistently whether the net cord helps you or your opponent.
