In tennis, a “7-point tie-break” and a “10-point tie-break” are not interchangeable versions of the same rule. The 7-point format normally closes a set that has reached six games all. The 10-point format can serve two different purposes: it can replace the entire deciding set, as happens in many doubles formats, or it can decide the final set after that set reaches 6-6. In every case, reaching 7 or 10 is not enough by itself: the winner must lead by two points.
The standard tie-break is played to 7 points
Under the rules and terminology explained by the ITF, a tie-break set normally goes to a tie-break when the game score reaches 6-6. The first player or team to reach 7 points wins the tie-break provided there is a two-point margin. Therefore, 7-5 ends it, but 7-6 does not. If the point score reaches 6-6, play continues until someone leads by two, such as 8-6, 9-7 or 10-8.
When this tie-break decides a set, the set score becomes 7-6 for the winner. That is different from saying the set was “played to 10”. A standard tie-break can finish 10-8 because the players remained level, but it is still a tie-break whose initial target was 7 points.
Why there is a 10-point tie-break
Competition rules may use a tie-break whose initial target is 10 points, again with a two-point winning margin. The key is to identify the role that tie-break has in that event.
Match tie-break: it replaces the entire deciding set
A match tie-break is used instead of a final set. If the match is tied at one set all, the players do not start a third set of games. They go directly to a tie-break played to 10 points. The ITF uses this format, for example, in World Tennis Tour singles qualifying and doubles. The 2026 ATP rulebook provides for two tie-break sets followed by a 10-point match tie-break at one set all in ATP Tour and Challenger doubles. The WTA follows the same basic structure in main-draw doubles, with No-Ad scoring in the first two sets and a 10-point match tie-break as the third set.
Example: a match ends 6-4, 3-6, [10-7]. The final number is the match tie-break. No third set of games was played.
10-point final-set tie-break: it happens inside the deciding set
There is a different situation in which the deciding set is played normally and reaches six games all. At that point, the rules may require a tie-break played to 10 points. Here, the tie-break did not replace the set. It ended a set that was already in progress. The 2026 Grand Slam Rule Book provides for a 10-point tie-break in the final set, while the ITF rules describe this format from 6-6 in the deciding set.
Example: after splitting the first two sets, the third reaches 6-6. One player wins the tie-break 10-8. The set ends 7-6, not “10-8 in games”.
Common formats in 2026
| Context | Match format | Where the tie-break is used |
|---|---|---|
| Standard tie-break set | Set reaches 6-6 | 7-point tie-break, always requiring a two-point margin |
| ATP singles | Best of 3 tie-break sets | A set reaching 6-6 uses the standard tie-break |
| ATP doubles | Two tie-break sets | At one set all, a 10-point match tie-break replaces the third set |
| WTA singles | Best of 3 tie-break sets | A set reaching 6-6 uses the standard tie-break |
| WTA main-draw doubles | Two sets with No-Ad scoring | At one set all, a 10-point match tie-break acts as the third set |
| ITF World Tennis Tour main-draw singles | Best of 3 tie-break sets | Standard tie-break in sets that reach 6-6 |
| ITF World Tennis Tour singles qualifying | Two tie-break sets | At one set all, a 10-point match tie-break decides the match |
| ITF World Tennis Tour doubles | Two tie-break sets with No-Ad scoring | At one set all, a 10-point match tie-break decides the match |
| Grand Slams | Men's main-draw singles best of 5; other matches best of 3 unless specifically determined otherwise | The prescribed final-set tie-break is played to 10 points |
This table summarizes recurring formats, but it does not replace the rules for a specific draw. The ITF publishes the general Rules of Tennis and tour regulations, while the ATP, WTA and Grand Slam Board can define formats for their competitions. Qualifying rounds, doubles, juniors, wheelchair tennis, team events and tournaments using experimental rules can have different structures.
Three simulated scores that show the difference
- 6-6 in the first set, tie-break 7-4: the set ends 7-6. This is the standard 7-point tie-break.
- One set each, match tie-break 10-7: the match ends immediately. The 10-7 replaces the entire deciding set.
- 6-6 in the deciding set, final tie-break 12-10: the set ends 7-6. The initial target was 10, but the tie required play to continue until a two-point margin was reached.
How to know which rule applies before a match
The quickest method is to identify four things: the tour or tournament, singles or doubles, the competition stage and the announced format for the deciding set. The phrase “10-point tie-break” alone does not tell you whether it replaces the final set or is played only after that set reaches 6-6.
For professional matches, check the ITF Rules and Regulations page and, when applicable, the ATP, WTA or Grand Slam regulations. For local and amateur tournaments, the event fact sheet or organizer's published rules should control. The most useful question is therefore not only “7 or 10?”, but “when does the tie-break begin and what is it replacing?”.
