Tennis Scoring Explained

Tennis scoring is famously confusing for newcomers. Love, 15, 30, 40, deuce, advantage — none of it is intuitive. But once you understand the structure, it is straightforward. Here is the simplest explanation you will find.

The Basics: Points Within a Game

Tennis is scored in points, games, sets, and matches. Let us start at the smallest unit — points within a single game.

One player serves for an entire game. Points are called out as the server's score first, then the receiver's:

Points WonScore CalledExample
0LoveMatch starts at love-all
115Server wins first point: 15-love
230Server wins again: 30-love
340Server wins again: 40-love (game point)
4GameServer wins again: game (server wins)

A love game (winning 4 points without your opponent scoring) is the tennis equivalent of a perfect inning. A break is when the receiver wins the game — breaking the server's serve.

Why Love, 15, 30, 40?

Nobody knows for certain. The most widely accepted theory traces it back to medieval France, where scoring was based on a clock face. Each point advanced the hand by a quarter: 15, 30, 45. The jump from 45 to 40 likely happened to accommodate the deuce system — 40, advantage (50), game (60) worked better than 45, advantage (52.5).

Love probably comes from the French l'oeuf (the egg), because zero looks like an egg. Or it could mean playing for love — for nothing. Either way, it has stuck.

Deuce and Advantage

When both players reach 40-40, the score is called deuce. You cannot win a game from deuce with a single point — you need two in a row:

  1. Win one point from deuce — you have advantage (ad-in if you are serving, ad-out if you are receiving)
  2. Win the next point — you win the game
  3. Lose the next point — back to deuce

A game can bounce between deuce and advantage indefinitely. The longest recorded game in professional tennis had 37 deuces (80 points in a single game). In social tennis, many players use no-ad scoring — the first player to win a point from deuce wins the game, keeping things moving.

Games, Sets, and the Match

Zoom out from individual games and the structure builds on itself:

Game

First to 4 points (with 2-point lead from deuce). Server alternates each game.

Example: Server wins 40-15 — server leads 1-0 in games

Set

First to 6 games with a 2-game lead. If it reaches 6-6, a tie-break decides the set.

Example: Player A wins 6-4 — Player A wins the set

Match

Best of 3 sets (most formats) or best of 5 sets (Grand Slams, men's singles).

Example: Player A wins 6-4, 3-6, 6-2 — Player A wins the match 2 sets to 1

Tie-Break Rules

When a set reaches 6 games all, a tie-break decides it. The tie-break has its own scoring system:

  • Points are counted normally: 1, 2, 3, 4... (not love-15-30-40)
  • First to 7 points wins, but you must lead by 2. If it reaches 6-6 in the tie-break, play continues until someone leads by 2 (e.g., 8-6, 9-7, 15-13).
  • Serve pattern: Player A serves 1 point, then players alternate serving 2 points each.
  • Change ends every 6 points (not every game, since there are no games).

The tie-break winner wins the set 7-6. On a scoreboard, the tie-break score is often shown in brackets: 7-6 (4) means the set was won 7-6 with the losing player scoring 4 points in the tie-break.

Timed setsVariesPlay for a set time (e.g., 20 min per set)Social tennis nights, round robins

For social tennis and evening sessions, Fast4 and timed formats are brilliant. They keep matches to 45–60 minutes, so everyone gets court time. Many clubs use these for mid-week night tennis competitions.

Keeping Score on Court

In social tennis, players keep their own score. The server announces the score before each point, calling their score first. If you lose track, go back to the last score both players agree on.

A portable scorekeeper mounted on the net post solves the what-was-the-score argument permanently. Flip the numbers after each point and there is nothing to dispute.

Frequently Asked Questions

Why does tennis scoring go 15, 30, 40 instead of 1, 2, 3?

The most widely accepted theory is that scoring was based on a clock face — each point moved the hand a quarter turn. 15, 30, 45 (shortened to 40 to accommodate the deuce system). It dates back to medieval France.

What does love mean in tennis?

Love means zero. It likely comes from the French l'oeuf (egg), because zero looks like an egg. Or from the phrase playing for love — playing for nothing.

What happens at deuce?

Both players are at 40-40. You must win two consecutive points to win the game: first to gain advantage, then to win. If the advantage player loses the next point, it returns to deuce.

How does a tie-break work?

Played at 6-6 in a set. Points counted 1, 2, 3... First to 7 with a 2-point lead wins. Serve alternates: 1 serve, then 2 each. Change ends every 6 points.

What is a match tie-break (super tie-break)?

A 10-point tie-break played instead of a full final set. Same rules as a regular tie-break but first to 10 (with 2-point lead). Used in most doubles formats and some social competitions.
