A tennis score can sound like a puzzle the first time you hear “15-love, 30-all, deuce.” The good news is that the match is built from a few simple pieces: points make games, games make sets, and sets decide the match. Learn how each piece works, and you can follow the score from the first serve to the final point.
How tennis scoring works at a glance
A standard tennis match is played in sets. To win a set, a player usually needs to win at least six games and lead by two. Games are made up of points, and their unusual count goes love, 15, 30, 40, then game—unless both players reach 40, which is called deuce.
- Point: One rally, starting with a serve.
- Game: Usually won by the first player to reach four points, with a two-point lead.
- Set: Usually won by the first player to win six games, with a two-game lead, subject to tiebreak rules.
- Match: Usually won by the player who takes two sets out of three, or three sets out of five.
Those are the building blocks. The details make the score easier to read.
How points are counted
Within a game, points are announced as love, 15, 30, 40, and game. “Love” means zero. A score of 30–15 means the player named first has won two points in that game, while their opponent has won one.
The server’s score is normally called first. So if the server has won two points and the receiver has won one, the score is 30–15. If each has won one, it is 15-all. If both have won three points, it is 40-all, or deuce.
| Points won in the game | Score call |
|---|---|
| Neither player has won a point | Love-all |
| One point each | 15-all |
| Two points each | 30-all |
| Three points each | Deuce (40-all) |
The numbers do not work like ordinary arithmetic: 15 plus 15 becomes 30, and the next point takes a player to 40. You do not need to know why the traditional numbers developed to keep score. Just remember the sequence.
What happens at deuce?
At 40–40, neither player can win the game with just one point. A player must win two points in a row from deuce: the first earns advantage, and the next wins the game.
For example, if the server wins the next point, the score is “advantage server.” If the server then wins another, the game is theirs. But if the receiver wins that point instead, the score goes back to deuce. The same pattern can repeat several times, which is why a close game can last much longer than a few rallies.
Some recreational leagues and tournaments use no-ad scoring to shorten matches. In that format, the next point after deuce decides the game. The receiver often chooses which side of the court to receive from, though the event’s rules determine the procedure. If you are unsure which format is being used, ask before play begins.
How a game is won
In standard advantage scoring, a player must win at least four points and be two points ahead. Winning four points is not always enough: at 40–40, a player still needs to win the next two points without losing one in between.
Suppose a player wins the first three points, loses the next three, then wins one. The score moves from love–40 to deuce, then to advantage, so they have not won the game yet. Win the following point and the game is theirs; lose it, and the score returns to deuce.
A point can end in many ways: a shot lands in and the opponent cannot return it, the ball bounces twice, or a player hits out or into the net. A double fault—two consecutive service faults on the same point—also gives the point to the receiver. The scoring system counts the result of the rally, not how spectacular it looked.
How games become sets
Games are counted with ordinary numbers. A set score might be 6–3, meaning one player won six games and the other won three. In a standard set, a player needs at least six games and a two-game lead to win. That means 6–4 wins the set, but 6–5 does not: play continues until someone leads by two, or a tiebreak is played under the event’s rules.
Many matches use a tiebreak when the games reach 6–6. In a common tiebreak, the first player to reach seven points with a lead of at least two wins it. If the score becomes 6–6 in the tiebreak, play continues until one player has that two-point margin. The set is recorded as 7–6, with the tiebreak score sometimes shown in brackets—for example, 7–6 (5), meaning the winner took the tiebreak 7–5.
Tiebreak serving follows a set pattern: the player due to serve starts with one point, then the players take turns serving two points each. Players change ends after every six tiebreak points. Tournament rules can differ, especially in a deciding set, so a final set may use a longer tiebreak or another format.
How sets decide the match
Most professional singles matches are best of three sets. The first player to win two sets wins the match. Many men’s Grand Slam singles matches are best of five, so a player must win three sets. Other competitions may use different formats, including a match tiebreak in place of a full deciding set.
A match score such as 6–4, 3–6, 6–2 shows the winner’s games first in each set. The player who lost the second set won more games in that set, but the other player won the match by taking two sets. Set count, not the total number of games across the match, decides the winner.
A quick score example
Imagine the server wins the first point, loses the second, then wins the next two. The calls go 15-love, 15-all, 30–15, and 40–15. One more point gives the server the game. If the receiver wins that point instead, the score becomes 40–30, and the game continues.
Now imagine both players reach 40. The server wins a point, making it advantage server, but then loses the next one. The score returns to deuce. If the receiver then wins two points in a row, the receiver takes the game.
Useful things to watch during a match
- Games reset: When a game ends, its point score starts over at love-all.
- Players take turns serving whole games: The server changes after each game. In a tiebreak, the serving pattern is different.
- A close score can be misleading: One break of serve—winning a game while returning—can have a big effect, even though it is only one game on the scoreboard.
- Formats vary: Tiebreak rules, no-ad scoring, and match length depend on the competition. Check the event rules if the format matters.
Frequently Asked Questions
Why is zero called love?
“Love” is the tennis term for zero. Its exact origin is uncertain, so it is safest to treat it as a traditional scoring word rather than rely on a single explanation.
Does 40–40 mean the next point wins the game?
Not in standard advantage scoring. The next point gives the winner advantage; they must win one more point to take the game. If their opponent wins the following point, the score returns to deuce. In no-ad scoring, the point after deuce decides the game.
Why does a set sometimes finish 7–6?
At 6–6, many formats use a tiebreak. The winner takes the set 7–6, provided the tiebreak itself is won by the required margin—commonly at least two points.
Does a player need to win more total points to win a match?
No. A player wins by taking the required number of sets, not by having the higher total of points or games. A player can win more points overall and still lose the match if the opponent wins the more important points at key moments.
Final Thoughts
Keep the sequence in mind: love, 15, 30, 40, then game; games build a set, and sets build a match. The main twist is that standard tennis games and sets usually require a two-point or two-game lead, with tiebreaks used in many formats to settle a close set. Once those rules click, even a long deuce game becomes much easier to follow.
