Tennis - Scoring basics

Tennis scoring starts with three separate layers.

Tennis scoring is easier once the point score, game score, set score, and match format are kept apart. A player does not simply add points until the match ends. Points win games, games win sets, and sets win the match, with deuce, advantage, and tiebreak rules deciding the close parts.

Quick ruling: inside a standard game, the point score runs love, 15, 30, 40, then game unless both players reach 40. At 40-40, most formats require a player to win two points in a row from deuce. Games then build into sets, and sets build into the match.

Decision path

How to read any tennis score

Start with the match format: best of three sets, best of five sets, or a shortened format used by the competition.
Read the set score to see how many games each player has won in the current set.
Read the game score to see the current point score inside the game: love, 15, 30, 40, deuce, advantage, or game.
Remember that the server's score is announced first during each game.
If the set reaches the event's tiebreak trigger, switch from love-15-30-40 scoring to ordinary point counting for the tiebreak.

Point score

Love, 15, 30, and 40 are the game score

Inside a standard game, zero points is called love. One point is 15, two points is 30, and three points is 40. If one player reaches 40 while the other has 30 or less, the next point wins the game.

The score is called with the server first. If the server has won two points and the receiver has won one, the score is 30-15. If the receiver has won two points and the server has won one, it is 15-30.

Deuce

At 40-40, the game is not over yet

When both players reach 40, the score is deuce. In ordinary advantage scoring, a player must win two points in a row from deuce to win the game. Winning the first point after deuce gives that player advantage. Winning the next point wins the game.

If the player with advantage loses the next point, the score goes back to deuce. That loop can repeat until someone wins the required two-point margin.

No-ad exception

Some formats use one deciding point at deuce

No-ad scoring is a shortened format used in some competitions and recreational settings. Instead of advantage and repeated deuces, the next point after deuce decides the game. The exact receiving choice and procedure can depend on the event rules, especially in doubles or mixed doubles.

Do not assume no-ad scoring unless the competition has announced it. Standard tennis scoring normally uses advantage games.

Games

Games build the set score

Each completed game adds one game to that player or team's set score. A common set is won by reaching six games with at least a two-game lead, such as 6-4 or 6-3.

If the set reaches 5-5, a player usually must win 7-5 or play a tiebreak at the score specified by the format. Many modern formats use a tiebreak at 6-6, but the exact deciding-set rule can vary by competition.

Sets

Sets build the match score

A match is won by winning the required number of sets. In a best-of-three match, the first player or team to win two sets wins the match. In a best-of-five match, the first to win three sets wins.

Shortened formats can replace a full deciding set with a match tiebreak, often played to a target number of points by a two-point margin. Those formats should be read from the event rules rather than guessed from a television scoreboard.

Tiebreaks

Tiebreaks use normal numbers

A tiebreak is scored 1, 2, 3, and so on instead of love, 15, 30, and 40. A standard set tiebreak is commonly won by reaching at least seven points with a two-point lead. If the score reaches 6-6 in the tiebreak, play continues until someone leads by two.

The tiebreak counts as one game in the set score, so a set decided by a tiebreak is usually recorded as 7-6. The serving rotation and change-of-ends pattern are separate from the basic scoring sequence.

Key phrases

Game point, set point, and match point are labels

Game point: the player can win the current game by winning the next point.
Break point: the receiver can win a game on the server's serve by winning the next point.
Set point: the player can win the current set by winning the next point.
Match point: the player can win the match by winning the next point.

Common mix-ups

What people usually count wrong

40-40 is called deuce: it is not called 40-all once the game reaches that point.
Advantage is not a point value: it means one player is one point away from winning the game after deuce.
Six games is not always enough: a normal set also needs a two-game margin unless a tiebreak or shortened format applies.
The server's score comes first: the same point score can sound different after a change of server.
A tiebreak is still part of the set: it decides a set score such as 7-6, not a separate bonus round.

Officials

How scoring mistakes are handled

Officials announce and record the score after each point, with the server's score first. If the score is disputed, they usually reconstruct the sequence from the last agreed score and the points that followed. Completed points normally stand unless a separate rule requires a replay.

In unofficiated play, players should stop as soon as a score problem is noticed, agree on the last certain score, and continue from the score that best reflects the points both sides accept. Guessing silently through several more points makes the dispute harder to fix.
