Tennis Scoring Explained: Love, Deuce and Tiebreaks — A Complete Beginner's Guide
Tennis scoring looks like it was designed by a committee of medieval monks — because, roughly, it was. Zero is 'love', the points go 15-30-40, and a match can be won by the player who wins fewer points overall. Yet once it clicks, the system is part of the sport's genius: it manufactures drama on a schedule. Here's **how tennis scoring works**, from a single point to a championship.
Points: Love, 15, 30, 40 — and Why
A game is a race to four points, counted as 15, 30, 40, game instead of 1-2-3-4. 'Love' means zero — most likely from the French *l'œuf* (the egg, shaped like a 0). The 15-30-40 ladder probably descends from a medieval clock face used as a scoreboard: 15, 30, 45 — with 45 later shortened to 40. Nobody is entirely sure, and honestly, tennis prefers it that way.
Win a point on your opponent's serve at 40 and you 'break serve' — the single most important currency in tennis.
Deuce and Advantage: The Two-Point Rule
At 40-40 — 'deuce' — a game can't be won by one point. You need two in a row: the first gives you advantage, the second gives you the game; lose the next point and it's back to deuce. This tiny rule is where tennis's famous drama lives — a single game can swing back and forth for ten minutes, and neither player can hide.
Games, Sets and Matches
The hierarchy stacks simply:
- Game — first to four points, win by two (via deuce/advantage).
- Set — first to six games, but you must lead by two (6-4 wins; 6-5 doesn't).
- At 6-6 — a tiebreak decides the set: first to 7 points, win by two.
- Match — best of three sets on tour; best of five for men at the Grand Slams.
- Deciding set at 6-6 — at all four majors, a longer 10-point tiebreak settles it.
The Beautiful Quirk: Winning With Fewer Points
Because only the point that closes a game matters — and only the game that closes a set — a player can win a match while winning fewer total points than the loser. It happens regularly, even in Grand Slam finals. That's not a flaw; it's the design. Tennis doesn't reward accumulation, it rewards timing: the big points, played well. Which is why the sport's mental game matters so much — and why our calendar spends so many of its daily lines on exactly that.
FAQs
- Why is zero called love in tennis?
- Most likely from the French 'l'œuf' — the egg, shaped like a zero — anglicised over centuries into 'love'. A competing theory says it's from playing 'for love' rather than money.
- What is deuce in tennis?
- The score of 40-40 in a game. From deuce, a player must win two consecutive points — the first earns 'advantage', the second wins the game.
- How does a tiebreak work?
- At 6-6 in a set, players contest a tiebreak: first to 7 points, winning by two, with serve alternating every two points. In the deciding set of a Grand Slam match, a 10-point version is used.
- Can you win a tennis match with fewer points than your opponent?
- Yes — because only games and sets count toward the match, a player who wins the important points can take the match while losing more total points. It's one of tennis's defining quirks.
