How does tennis scoring work?

Tennis looks simple — hit a ball over a net — but the scoring system catches new viewers off guard every time. Points that go "Love, 15, 30, 40" instead of 1-2-3-4? Games stacked into sets, sets stacked into matches? Once you've seen it laid out, it clicks fast. Here's the whole thing, from casual rec games to grand slam finals.

Points, Games, and Sets

Points

"Zero" in tennis is "Love" — a quirky bit of vocabulary the sport has carried for centuries.

To win a game, a player needs four points with a two-point lead. The progression: "Love" (zero), 15, 30, 40.

Deuce and Advantage

Both players on 40? That's "deuce".

From deuce, you need two consecutive points to win the game. The first one gets you "advantage", the second closes it out.

Lose the point at advantage and it's back to deuce. Games can ping-pong this way for a while.

Sets and Matches

A set goes to whoever wins six games with a two-game margin.

If games reach 6-6, a tiebreak decides the set.

Match length depends on format. Men's matches are typically best-of-five sets; women's and mixed doubles run best-of-three.

Service Rules and Scoring

Serving runs the whole scoring system. The first server is decided by a coin toss or racket spin. After that, players alternate serving entire games — not points.

A legal serve must:

• Land in the diagonal service box
• Clear the net without touching it
• Be hit from behind the baseline
• Be struck before the ball bounces

Miss any of those and it's a fault. Players get two attempts. Miss both and that's a "double fault" — the receiver wins the point automatically.

Tiebreak Rules

A tiebreak kicks in at 6-6 in a set. First player to seven points with a two-point lead takes the tiebreak and the set. Points are counted straight up here — 1, 2, 3 — none of the 15-30-40 stuff.

Players alternate serves during the tiebreak. The first server gets one serve; everyone after that gets two. They switch ends after the first point, then every six points after that, to keep things fair on wind, sun, and shadows.

Some tournaments — especially doubles — use a "match tiebreak" (first to 10 points) in place of a final set.

Example scoring progression

Walk through a single tennis game:

1. Player A serves and wins the point with a strong forehand. Score: 15-0 (or 15-love), Player A.
2. Player B replies with a backhand, but Player A wins the next with a placed drop shot. Score: 30-love.
3. Player B fights back and wins two in a row. Score: 30-30.
4. Player A leans on the serve to take the next. Score: 40-30.
5. Player B hits a deep return; Player A nets it. Score: 40-40 — "deuce".
6. Crucial point. Player A wins it with a backhand down the line. Player A has "advantage".
7. Player B's next return is weak. Player A puts away a forehand winner and wins the game.
8. If this was the final game of the set, the set score is 6-4 in Player A's favor.

Doubles Scoring

Doubles uses the same scoring framework, with a couple of important differences in service and court positioning. Each team picks its serving order at the start of every set and sticks with it for the whole set.

A game of doubles

The biggest difference: many doubles formats use "no-ad" scoring. No advantage, no extended deuce battles — at 3-3 (deuce), the next point wins the game outright. Games move faster, which is why pro doubles often runs this way.

What information is displayed on a tennis scoreboard?

A tennis scoreboard typically shows:

• Player or team names
• Current game score
• Number of games won in the current set
• Number of sets won by each player
• Previous set scores

Tournament boards add match stats and duration — much like the comprehensive score bugs in tennis broadcasts — but the basics above are what every scoreboard has to get right.

Test Your Scoring Knowledge

A few quick scenarios to check the rules really landed:

Scenario 1: The Deuce Dilemma

A tennis match reaches deuce (40-40). Player A wins the next point to gain advantage, but then loses the following point. Player A then wins two points in a row.

Scenario 2: The Tiebreak Challenge

In a tiebreak, Player A serves first and wins the point. Player B then serves and wins both points on their serve. Player A wins their next two service points, and Player B wins one point on their serve.

Question: What's the tiebreak score at this point?
