How The Scoring System Works In Tennis?

Tennis Scoring at a Glance

Tennis scoring can seem unusual at first, but it follows a simple structure. Every match is built from four levels: points, games, sets, and the match itself. Players first compete to win individual points, which combine to form games. Games then make up sets, and the required number of sets determines the winner of the match.

Understanding this progression makes following a tennis match much easier, whether you’re playing for the first time or watching professional tournaments.

Most tennis matches are played as best of three sets, meaning the first player to win two sets wins the match. In men’s singles at Grand Slam tournaments, matches are played as best of five sets, requiring three sets to secure victory.

How Do You Win a Point?

Every point begins with a serve. Once the ball is in play, players continue hitting it back and forth until one player wins the rally.

You win a point if your opponent:

• Hits the ball into the net.
• Hits the ball outside the court boundaries.
• Lets the ball bounce twice before returning it.
• Misses both serves, resulting in a double fault.
• Is unable to return your shot before it bounces twice.

Likewise, your opponent earns a point if you make one of these mistakes. Every point won moves a player closer to winning the game.

Tennis Point Scoring Explained

Unlike most sports, tennis does not count points as 1, 2, 3, and 4. Instead, each point has a unique name.

*Provided the player leads by at least two points.

If both players have the same score below 40, the score is announced as 15-All or 30-All. Once both players reach 40, the score becomes deuce, and special scoring rules apply.

Although the terminology may seem confusing at first, the sequence quickly becomes second nature after watching or playing a few games.

What Does Love Mean in Tennis?

In tennis, love simply means zero. If a player has not won any points in the current game, their score is called love.

For example:

• Love-15
• Love-30
• Love-40

The exact origin of the word remains uncertain, but the most widely accepted explanation traces it back to the French word l’œuf, meaning “egg.” Since an egg resembles the shape of the number zero, the term eventually evolved into “love” as tennis spread to English-speaking countries.

Another popular theory suggests that players once competed “for the love of the game,” meaning they played for enjoyment rather than money. While this explanation is well known, historians generally consider the French origin more likely.

Why Does Tennis Use 15, 30 and 40?

One of the biggest questions new players ask is why tennis uses 15, 30, and 40 instead of simply counting 1, 2, 3, and 4.

The most common theory is that the scoring system originated in medieval France, where a clock face was used to track points. Each point moved the hand by a quarter of the clock:

• First point: 15
• Second point: 30
• Third point: 45
• Fourth point: Game

Over time, 45 was shortened to 40, making score announcements quicker and leaving room for the advantage point that follows deuce.

Although historians continue to debate the exact origins of tennis scoring, this explanation remains the most widely accepted and helps explain why the sport still uses its distinctive scoring system today.

What Is Deuce?

When both players reach 40-40, the score is called deuce. At this stage, neither player can win the game with a single point.

Instead, a player must win two consecutive points to secure the game.

For example:

• 40-40 (Deuce)
• Player A wins the next point → Advantage Player A
• Player A wins another point → Game Player A

However, if Player B wins the point after Player A gains advantage, the score returns to deuce, and the battle continues until one player wins two points in a row.

Deuce often produces some of the longest and most exciting games in tennis, as momentum can swing back and forth several times before a winner is decided.

What Is Advantage?

Advantage, often shortened to Ad, is the score awarded to the player who wins the first point after deuce.

If the player with advantage wins the following point, they win the game. If they lose the next point instead, the score immediately returns to deuce.

There are two types of advantage:

• Advantage In (Ad-In): The server wins the point after deuce.
• Advantage Out (Ad-Out): The receiver wins the point after deuce.

This system ensures that every game is won by a margin of at least two points, making close games more competitive and rewarding players who can perform under pressure.

How Do You Win a Game?

A player wins a game by winning at least four points while leading by two points or more.

Some examples of winning scores include:

• 40-0
• 40-15
• 40-30

If both players reach 40, the score becomes deuce, and the game continues until one player wins two consecutive points.

Here is a typical scoring progression:

This unique system means that some games are over quickly, while others can continue for many minutes if both players repeatedly return to deuce.

How Do You Win a Set?

Games combine to form a set. In most tennis matches, a player must win at least six games while leading by two games to win the set.

Common set scores include:

• 6-0
• 6-1
• 6-2
• 6-3
• 6-4

If the score reaches 5-5, neither player has won the set yet because the required two-game margin has not been achieved. One player must either win the next two games to claim the set 7-5, or, if the score reaches 6-6, a tie-break is usually played to determine the winner. A set decided by a tie-break ends 7-6.

This two-game advantage rule helps ensure that the stronger player earns the set through consistent performance rather than by winning a single deciding point.

What Is a Tie-break?

A tie-break is a special game played when a set reaches 6-6. Instead of continuing until one player leads by two games, a tie-break is used to decide the winner of the set.

Unlike regular games, where points are called 15, 30, and 40, points in a tie-break are counted normally as 1, 2, 3, 4, and so on.

To win a standard tie-break, a player must:

• Reach 7 points first.
• Lead by at least two points.

If the score reaches 6-6 in the tie-break, play continues until one player achieves a two-point advantage. This means tie-breaks can finish with scores such as 8-6, 10-8, or even 15-13.

Tie-breaks are often among the most exciting moments in a tennis match because every point becomes increasingly important.

How Does Serving Work in a Tie-break?

Serving during a tie-break follows different rules than a regular game.

The player whose turn it is to serve begins by serving one point from the deuce court. After that, the opponent serves the next two points. From then on, both players continue serving two consecutive points each until the tie-break ends.

The serving sequence looks like this:

Players also change ends of the court after every six points played during the tie-break (6, 12, 18, and so on). This helps ensure that neither player gains an unfair advantage from factors such as wind, sunlight, or court conditions.

Match Tie-breaks

Some tournaments and recreational leagues replace the deciding set with a match tie-break, sometimes called a super tie-break.

Instead of playing a full third set, players compete in a longer tie-break to determine the winner of the match.

The rules are straightforward:

• First player to reach 10 points wins.
• The winner must lead by at least two points.
• Serving follows the same rotation as a standard tie-break.

For example, a match that is tied at one set each may be decided by a match tie-break ending 10-7 or 12-10, rather than playing another full set.

Match tie-breaks are commonly used in doubles competitions, club tournaments, and many recreational events because they reduce the overall match length while still providing a fair conclusion.

No-Ad Scoring

Some tennis competitions use No-Ad scoring to make matches shorter and more predictable.

Under traditional scoring, a game continues after deuce until one player wins two consecutive points. With No-Ad scoring, there is no advantage. When the score reaches deuce, the very next point decides the game.

In singles, the receiver chooses whether to receive the deciding point from the deuce or ad court. In doubles, the receiving team also chooses which player will receive the final point.

No-Ad scoring is commonly used in:

• College tennis
• Club leagues
• Recreational tournaments
• Doubles competitions

While it speeds up matches, many players prefer traditional advantage scoring because it rewards consistency during close games.

When Do Players Change Ends?

Players change ends of the court throughout a match to ensure that both competitors experience the same court conditions.

During a set, players switch ends after every odd-numbered game, including after the:

• First game
• Third game
• Fifth game
• Seventh game
• Ninth game

This means players change sides whenever the total number of completed games is 1, 3, 5, 7, 9, and so on.

During a standard tie-break, players change ends after every six points.

Players are also given short breaks during these changeovers. A standard changeover lasts 90 seconds, except after the first game of each set, where players change ends without sitting down. At the end of each set, players receive a 120-second set break before the next set begins.

FAQ

Why is tennis scored 15, 30, and 40 instead of 1, 2, and 3?

The most widely accepted theory is that early tennis players used a clock face to keep score, with each point moving the hand by a quarter of the clock. Over time, 45 was shortened to 40, creating the scoring system still used today.

Why is zero called love?

The exact origin is uncertain, but many historians believe it comes from the French word l’œuf, meaning “egg,” because an egg resembles the shape of the number zero.

Can a set end 6-5?

No. A player must win a set by at least two games. If the score reaches 5-5, the set continues until one player wins 7-5 or the score reaches 6-6, where a tie-break is usually played.

Can a tie-break finish 7-6?

No. A player must win a tie-break by two points. If the score reaches 6-6, play continues until someone leads by two.

Do all tennis tournaments use the same scoring rules?

Most tournaments follow the same basic scoring system, but some competitions use No-Ad scoring, match tie-breaks instead of a deciding set, or other format variations to shorten matches.
