A tennis scoreboard can look confusing when the points are called “15,” “30,” and “40,” but the basic goal is simple: win enough points to take games, enough games to take sets, and enough sets to win the match. The details vary slightly by competition, so knowing the usual scoring system—and the common exceptions—makes it much easier to follow a close contest.
The short answer
A player wins a tennis match by winning more than half of the sets required by the match format. Most professional singles matches are best of three sets, so the first player to win two sets wins the match. Men’s singles at the Grand Slam tournaments is generally best of five: the first player to win three sets takes the match. In doubles, a match is often best of three sets, sometimes with a match tiebreak in place of the final set.
Players compete in points to win games, games to win sets, and sets to win the match. Each stage has its own rules, which is why a player can win a set 6–4, lose the next 3–6, and still be only one set away from victory in a best-of-three match.
How points make a game
In a standard game, the points are called love (zero), 15, 30, and 40. Win the next point after 40 and you win the game—unless both players reach 40, which is called deuce.
At deuce, a player must win two points in a row to take the game. The first point gives that player advantage. If the player wins the next point, the game is theirs. If the opponent wins it instead, the score returns to deuce. This can continue for several points, as either player needs a two-point lead to finish the game.
For example, if the score is deuce and the server wins the next point, the server has advantage. Win again, and the server holds serve. Lose the next point, and the score goes back to deuce. That back-and-forth is one reason a game can last much longer than its point score might suggest.
Some competitions use no-ad scoring to speed up play. At deuce, the next point decides the game; there is no advantage point. The receiving player or team generally chooses which side will receive that deciding point, subject to the competition’s rules.
How games make a set
Usually, a player must win at least six games and lead by two to take a set. A score of 6–4 wins the set, while 6–5 does not: the leading player still needs one more game to reach 7–5. If the score reaches 6–6, a tiebreak is commonly played.
In a standard tiebreak, players count points normally. The first to reach at least seven points with a two-point lead wins it. So 7–5 is enough, but at 6–6 the tiebreak continues until someone leads by two, perhaps finishing 8–6 or 10–8. The winner takes the set, usually recorded as 7–6.
Players change ends during a tiebreak, typically after every six points. Serving also follows a set order: the first server serves one point, then the other player serves two, and the players continue taking two serves each. Exact procedures can differ in team formats, but the tournament rules determine the order.
How the match is decided
Once a player has won the required number of sets, the match is over. In a best-of-three match, a player who wins the first two sets does not need to play a third. If the players split the first two sets, the third decides it. In a best-of-five match, the winner must take three sets; winning the first two is not enough.
For instance, a best-of-three match ending 6–3, 4–6, 6–2 goes to the player who won the first and third sets. The other player won more games in the second set, but sets—not the total number of games—decide the match.
Some doubles matches and other events use a match tiebreak instead of a full deciding set. This is usually played to 10 points, with a two-point margin required. A team might lose the first set 4–6, win the second 6–3, and then take the match tiebreak 10–7. In that format, the tiebreak counts as the deciding set for the match, even though it is not a regular set of games.
Serving, receiving, and the contest within the score
Players alternate serving games. The server begins each point behind the baseline and must land the serve in the correct service box. If the first serve misses, the server gets a second attempt. Two faults in a row give the receiver the point, a result called a double fault.
Holding serve means winning the game while serving; breaking serve means winning the game while receiving. A break can matter enormously because the server often has an advantage, but it does not automatically decide the set. A player who is broken can break back later, and sets are still settled by the required game margin or tiebreak.
The score also does not tell the whole story of how points are won. A player may control a rally with deep shots, draw a short reply, and finish at the net. Another may win by serving aggressively or forcing errors rather than hitting outright winners. Rafael Nadal, for example, was known for using heavy topspin and court coverage to make opponents play one more shot. The point goes to whoever wins it, whether through a clean winner or an opponent’s mistake.
That is why tennis is often described as a game of small contests inside a larger one. A single point can decide a game at deuce; a single game can swing a set; and a tiebreak can turn on a handful of points. The player who keeps winning those key moments is best placed to win the match.
Common score-reading questions
What does “love” mean?
Love means zero points in a game. If the score is 30–love, one player has won two points and the other has not yet won one. The server’s score is usually announced first.
Can someone win more games but lose the match?
Yes. Sets determine the match, not the overall game count. A player can win one set by a wide margin and lose two close sets, finishing with more games won but fewer sets.
Is every deciding set played as a match tiebreak?
No. Many matches use a full final set, while some doubles events and other competitions use a match tiebreak instead. The event’s format decides which applies.
Frequently Asked Questions
How many sets do you need to win a tennis match?
It depends on the format. In a best-of-three match, the first player to win two sets takes it. In a best-of-five match, the first to win three sets wins.
How many games do you need to win a set?
Usually, you need at least six games and a two-game lead. At 6–6, many formats use a tiebreak, though the exact rules depend on the competition.
What is the difference between a tiebreak and a match tiebreak?
A regular tiebreak normally decides a set at 6–6 and is usually played to seven points, win by two. A match tiebreak can replace the deciding set and is commonly played to 10, also win by two.
Final Thoughts
A tennis match is won by taking the required number of sets, but reaching that result means winning points, games, and often a few pressure moments along the way. Remember the sequence—points build games, games build sets, and sets decide the match—and most scorelines become straightforward to understand. When a match reaches deuce or a tiebreak, the same basic principle still applies: create a two-point or two-game margin where the rules require one, and keep doing enough to finish the contest.
