Tennis scoring sounds like a foreign language to newcomers. Commentators announce fifteen, thirty, and forty, then suddenly talk about deuce, advantage, and breaks of serve. Yet beneath the unusual vocabulary lies a tidy, logical structure. Tennis is scored in a nested ladder: points build into games, games build into sets, and sets decide the match. Learn each rung and the whole thing clicks into place.
Points: The Curious Numbers
Within a single game, points are counted using a sequence that dates back centuries: zero, fifteen, thirty, and forty. A score of zero is called love, a term whose origin is debated but charmingly traditional. So the first point won takes a player from love to fifteen, the second to thirty, and the third to forty. Win a fourth point while ahead and you take the game.
- Love means zero points.
- Fifteen is one point.
- Thirty is two points.
- Forty is three points.
- The server's score is always announced first.
There is one important catch. To win a game you must lead by at least two points once you reach forty, which is where deuce comes in.
Deuce and Advantage
If both players reach forty, the score is called deuce rather than forty-all. From deuce, a player must win two points in a row to take the game. Win the first of those points and you have the advantage. Win the next and the game is yours. Lose it and the score returns to deuce, and the tug-of-war continues until someone finally strings two points together. This is why some games swing back and forth for several minutes.
Some competitions, particularly doubles and certain tour events, use a shortened no-advantage format where a single deciding point is played at deuce to speed things up. But the classic two-point margin remains the traditional standard.
Games and Sets
Winning individual points earns you games, and winning games earns you sets. To win a set, a player generally needs to win six games while leading by at least two, for example six games to four. If the set reaches six games all, most formats resolve it with a tiebreak.
- Win six games, leading by two, to take a standard set.
- At six games all, play a tiebreak to decide the set.
- In a tiebreak, points are counted normally as one, two, three and so on.
- The first to seven points, leading by two, wins the tiebreak and the set.
Serving matters enormously because the server has an advantage in each game. When a player wins a game while their opponent is serving, it is called a break of serve, and breaks are usually what decide close sets. Holding your own serve keeps you level; breaking your opponent's serve edges you ahead.
Winning the Match
A match is won by taking a majority of sets. Most professional and recreational matches are best of three sets, meaning the first player to win two sets wins the match. The most prestigious men's events at the Grand Slams have traditionally used best of five sets, requiring three sets to win, which is why those matches can last for hours. Rules for the final deciding set have varied, with many tournaments now using a long tiebreak to prevent the marathon final sets of the past.
Putting It All Together
Follow a point from the bottom up and the system makes sense. Rally to win points, string points together to win a game, accumulate games to win a set, and win enough sets to take the match. The odd numbers and old-fashioned words are simply tradition layered over a clear, cumulative structure. Watch a match with this ladder in mind and within a set or two you will be calling the score like a regular.
