How Tennis
Scoring Works

Tennis has one of the most unique scoring systems in all of sports. Here's everything you need to know — from Love to Championship Point.

1

The Structure

Tennis is built in layers. Points build into games, games build into sets, and sets decide the match.

Match

Win 2 out of 3 sets (or 3 out of 5 at Grand Slams)

Set

Win 6 games with a 2-game lead (or a tiebreak at 6–6)

Game

Win 4 points with a 2-point lead after deuce

Point

The smallest unit — every rally is one point

2

The Weird Points

Instead of 1, 2, 3, 4 — tennis counts 0, 15, 30, 40. Nobody really knows why.

Love

Zero points. "Love" likely comes from the French word l'œuf (egg), because an egg looks like a zero.

15

Fifteen

Win your first point in a game. The server's score is always called first — "15-Love" means the server leads.

30

Thirty

Win your second point. At 30-30, it's anyone's game — two points from winning for both players.

40

Forty

Win your third point. At 40-Love, you have a game point. But if it's 40-40, that's called Deuce.

When both players reach 40, you need to win by 2 clear points. Try it yourself below.

Reading a Scoreboard

Here's what a live tennis score actually looks like — and what every number means.

How to Read This

Alcaraz won Set 1 (6-4), lost Set 2 (3-6), and leads 5-4 in Set 3. He's serving (green dot) and leads 40-30 in the current game. The green highlighted column is the active set.

5

The Tiebreak

When a set reaches 6-6, a special tiebreak game decides it. First to 7 points, win by 2.

Tiebreak Rules

Points use normal numbering (1, 2, 3...) not 15-30-40. Serve alternates every 2 points. Players switch ends every 6 points. First to 7 wins, but must lead by 2 — so 7-6 is possible only in the set score, not the tiebreak itself.

Match Formats

Not all tennis matches are the same length. Grand Slams are the ultimate test of endurance.

Key Terms

The vocabulary you need to follow any tennis match like a pro.

Ace

A serve so good the opponent can't even touch it. An instant point for the server.

Break

Winning a game when your opponent is serving. One of the most important moments in tennis.

Hold

Winning a game when you're serving. The expected outcome — failing to hold is a "break."

Break Point

When the returner is one point away from breaking serve. High-pressure moment for the server.

Double Fault

Missing both serves. The opponent gets a free point. Even the best pros average 2-4 per match.

Match Point

When one player is a single point from winning the entire match. The most exciting moment in tennis.

Love

Zero. "Love-40" means the server hasn't won any points yet. A "love game" means 4-0.

Bagel / Breadstick

Winning a set 6-0 is a "bagel" (looks like a 0). Winning 6-1 is a "breadstick" (looks like a 1).
