How Does Tennis Scoring Work? Points, Games, Sets, and Tiebreaks
By the BrainSnail editorial team. How these articles are written and checked, and how to tell us when one is wrong.
A tennis match is built in layers: players win points to win games, games to win sets, and sets to win the match. The unusual point names can seem confusing at first, but the pattern becomes simple once you separate those layers.
Inside a single game: love, 15, 30, 40
A player starts a game at zero, which is called love. Winning the first point normally moves the score to 15, the second to 30, and the third to 40. Winning another point usually wins the game, as long as the opponent has no more than 30 points.
The special case appears when both players reach 40. That score is called deuce. From deuce, a player normally needs to win two consecutive points to take the game. The first point creates advantage, and the next wins the game. If the player with advantage loses the following point, the score returns to deuce. This is the core of how tennis scoring works at game level.
Games combine to make a set
A set is usually won by the first player or team to reach six games with a lead of at least two games. A score of 6-4 therefore wins a normal set, while 6-5 does not usually finish it because the lead is only one game. If the trailing player wins the next game, the set reaches 6-6.
Many competitions use a tiebreak at 6-6, though exact formats can vary. This is an important detail when learning how tennis scoring works because tournament rules are not identical everywhere. Some deciding sets have used special formats, and shorter competitions may use alternative scoring systems.
A tiebreak uses ordinary numbers
In a standard tiebreak, points are counted 0, 1, 2, 3, and so on rather than love, 15, 30, and 40. A player usually needs at least seven points and a lead of two to win. That means 7-5 can finish a tiebreak, while 7-6 cannot. Play continues until someone gains a two-point advantage.
Serving also follows a special sequence during a tiebreak, with players changing server after the first point and then generally after every two points. You do not need every serving detail to understand the score. To answer how tennis scoring works while watching a match, first identify whether the numbers on screen refer to points, games, sets, or a tiebreak.
Where the strange names come from, and the newer variations
Nobody knows for certain why tennis counts 15, 30, 40. The most repeated explanation is a clock face, with the hand moving a quarter turn per point and 45 shortened to 40 so that deuce and advantage could fit before the hour; historians treat it as plausible rather than proven. 'Love' for zero is often traced to the French l'oeuf, an egg, for its shape, and deuce to deux, the two points needed from a tie.
Modern events also tinker with the format. No-ad scoring, used in many doubles competitions, plays a single deciding point at deuce instead of requiring two in a row. The match tiebreak replaces a full third set with a race to ten points in some doubles and lower-tier events, and the Grand Slams now end a deciding set with a ten-point tiebreak at 6-6 rather than the marathon sets of the past. The layers stay the same; only the way each layer closes has changed.
The takeaway
Players collect points inside games, games inside sets, and sets inside the match. Remember love, 15, 30, 40, then learn deuce and advantage. Once those pieces are clear, the larger score becomes much easier to follow, even when a set reaches a tiebreak.
