A standard tennis tie break begins when a tie-break set reaches 6-6 in games. The first player or team to reach seven points with a lead of at least two wins it. The first server serves one point, then the players or teams take turns serving two points at a time. Some formats use a ten-point decider instead.
| Format | When it happens | Winning requirement |
|---|---|---|
| Standard set tie break | At 6-6 in a tie-break set | At least seven points, leading by two |
| Grand Slam singles final set decider | At 6-6 in the deciding set | At least ten points, leading by two |
| Ten-point match tie break | Replaces the deciding set when the format provides | At least ten points, leading by two |
The key is to identify the competition's scoring format before applying a number. The USTA scoring guide explains ordinary set tie breaks and the Grand Slam final set format. Its 2026 Friend at Court rulebook supplies the formal rules and approved alternatives.
How many points win a tennis tie break?
For a normal seven-point tie break, 7-5 is a winning score because it meets both tests: seven points and a two-point advantage. A score of 7-6 meets only the first test. Play continues. If the leader wins the next point, 8-6 finishes it; if the opponent wins, the score becomes 7-7.
The same logic continues beyond that. A hypothetical 10-8 or 15-13 can finish a seven-point tie break because there is a two-point margin. Seven is the minimum target, not a cap on the number of points either side can score.
Points are counted as zero, one, two and so on. The familiar 15, 30 and 40 sequence belongs to standard games. Keeping the two scoring systems separate makes a broadcast easier to follow, especially when the scoreboard shows both the set's game score and a smaller tie-break point tally.
Who serves first, and when does service change?
The player whose turn it is to serve starts the tie break. That player serves one point. The opponent then serves the next two points. The first player serves two more, and the pattern of two consecutive points per server continues until the tie break ends.
| Point numbers | Server in a singles example |
|---|---|
| 1 | Player A |
| 2 and 3 | Player B |
| 4 and 5 | Player A |
| 6 and 7 | Player B |
These are points, not separate service attempts. A first-service fault does not itself advance the point number. The ordinary service rules still apply. In doubles, the service rotation within each team continues in the order established during that set, rather than letting partners choose afresh after every two points.
Under the standard procedure, players change ends after every six points. Count the combined points: 4-2 means six have been played, as does 3-3. The rulebook also recognises alternative changeover procedures, so organised local competition can specify an approved variation.
What happens after a set tie break?
Winning the ordinary tie break completes the set at 7-6 in games. The player or team that served the first tie-break point receives in the opening game of the next set. Finishing with a winning serve does not decide who starts serving the following set.
The LTA rules guide also distinguishes tie breaks from ordinary games and explains the broader points, games, sets and match structure. That hierarchy is useful: a standard tie break resolves a set, and the set result then contributes toward winning the match.
What is the difference between the two ten-point formats?
In Grand Slam singles, the deciding set is played in games until 6-6, when a ten-point tie break resolves it. A match tie break, by contrast, can replace the deciding set altogether when that scoring format is prescribed. The target number can be the same while the stage at which it begins is different.
For either ten-point format, 10-9 is insufficient because the lead is only one. The same two-point principle still applies. For more sport rule explainers, see badminton's announced scoring change, football's offside rule and how football handball decisions work.
