In a tennis singles match, players do not switch sides after every point or every game. They change ends at set times during each set, which gives both players a fair share of the sun, wind and other court conditions.
The basic rule is simple: players change ends after the first game, then after every other game. There are separate details for tie-breaks and the end of a set, so the score can help you work out exactly when the next change happens.
When Do Singles Players Change Ends?
Under the standard rules, players change ends at the end of the first game of a set, then at the end of every odd-numbered game: the third, fifth, seventh and so on. The pattern continues until the set ends.
For example, in a set that reaches 6–3, the players change ends after games 1, 3, 5, 7 and 9. The same pattern applies no matter which player wins each game. It is the number of games played—not the score within a game—that matters.
A quick way to remember it
After each game, add one to the total number of games played in the set. If that total is odd, the players change ends. If it is even, they stay where they are, unless a set-ending rule or tie-break changes the situation.
- After game 1: change ends.
- After game 2: stay at the same ends.
- After game 3: change ends.
- After game 4: stay at the same ends.
This rule applies in singles and doubles. In singles, “change ends” means each player moves to the opposite side of the net.
Changing Ends Between Sets
At the end of a set, whether the players change ends depends on how many games were played in that set. If the total is odd, they change ends at the set break. If the total is even, they wait and change ends after the first game of the next set.
For instance, a 6–3 set has nine games, an odd total, so the players change ends at the end of the set. A 6–4 set has ten games, an even total. They do not make an extra change at the set break; they switch ends after the first game of the next set.
This can look unusual because the players may have changed ends after game 9 of a 6–4 set, then stayed at those ends through game 10 and the set break. The next change comes after game 1 of the following set.
Changing Ends During a Tie-Break
In a standard tie-break, players change ends after every six points. So they switch after the score reaches 3–3, 6–6, 9–9 and each later group of six points. The change is based on the total points played in the tie-break, not on who is leading.
At the start of a tie-break, the player due to serve begins with one point. The other player then serves the next two points, and service continues in two-point turns. That serving pattern is separate from the end-change rule: players still switch ends after every six points.
When the tie-break finishes the set, the usual set-ending rule also applies. For example, a 7–6 set has 13 games in total, so the players change ends at the end of the set. If a set has an even total number of games, the change is made after the first game of the next set.
How the Changeover Break Works
A change of ends often comes with a short rest, but not every change does. Under the standard rules, players usually get 90 seconds on a changeover. There is no changeover rest after the first game of a set, and players do not get a rest each time they switch ends during a tie-break.
At the end of a set, players normally have a longer set break. The details can vary by competition format, so a tournament may have additional procedures. The important point for following the match is that the end-change schedule still follows the game and tie-break counts.
Why Changing Ends Matters
Switching ends helps balance conditions that can favor one side of the court. A low sun can make serving or returning difficult in one direction. Wind may help a player hit with depth from one end but push the ball long from the other. On outdoor courts, shade, background and court wear can also affect how a player sees or strikes the ball.
Imagine a player serving into a strong headwind. The wind may make it harder to land a first serve with pace, while a tailwind at the other end can help the ball travel faster. Changing ends regularly gives both players time on each side rather than allowing one player to face the tougher conditions for most of the set.
Players also use the walk to the other end to reset mentally. A quick towel break, a drink or a change in tactics can help after a long rally or a run of lost points. The rules keep that pause within set limits, so it does not become an unfair delay.
Common Confusion: Ends, Service and Court Sides
Changing ends is not the same as changing the side from which a player serves. Players alternate serving games, while the server also alternates between the deuce court and ad court for each point. Those routines continue regardless of which end of the court the player occupies.
The players do not get to choose a new direction whenever the conditions become difficult. At the start of a match, a coin toss or racket spin decides who may choose to serve, receive, or select an end. After that, the change-of-ends schedule is set by the rules.
Frequently Asked Questions
Do tennis players change ends after every game?
No. They change ends after game 1 and then after every other game—games 3, 5, 7 and so on. They stay at the same ends after even-numbered games.
When do players change ends in a tie-break?
They change ends after every six points played, such as at 3–3 or 6–6. The rule depends on the total points played, not the player who is ahead.
Do players always switch ends at the end of a set?
No. They change ends at the set break when the set has an odd number of games. If the set total is even, they change ends after the first game of the next set.
Does changing ends change who serves next?
No. Service order follows the normal rotation of serving games. Changing ends only determines which side of the court each player occupies.
Final Thoughts
For a regular set, remember the odd-game pattern: players change ends after games 1, 3, 5 and every odd-numbered game that follows. In a tie-break, they switch after every six points. At a set break, check whether the set contained an odd or even number of games. Once you know those three details, it is easy to follow when singles players should change direction.
