Tennis Rules & Scoring: A Complete Beginner’s Guide

Tennis can seem confusing when you first watch a match. Why do the points go from 15 to 30 to 40? What do love, deuce, and advantage mean? And why do some matches finish in two sets while others require three or even five?

Tennis is played between two players in singles or two teams of two in doubles. Players win points by hitting the ball into the opponent’s court according to the rules. Points make up games, games make up sets, and sets determine the winner of a match. Most traditional tennis scoring uses the sequence love, 15, 30, 40, and game, although some competitions use alternative scoring formats.

This beginner’s guide explains the tennis scoring system, serving rules, common shots, singles and doubles, tiebreaks, the four Grand Slam tournaments, and international team competitions. By the end, you should be able to follow a match and understand the most common terms commentators use.

For the official rules, consult the International Tennis Federation’s Rules of Tennis.

How Tennis Scoring Works

Tennis has three main scoring levels:

1. Points: Players win individual points during rallies.

2. Games: Players collect points to win games.

3. Sets: Players win games to win sets, and sets determine the match.

The rules governing scoring are published by the ITF, the international governing body for tennis.

Points: Love, 15, 30, 40, Game

In traditional advantage scoring, the points are announced using the following sequence:

For example, if the server wins the first point, the score is 15–love. If the receiver wins the next point, the score becomes 15–all.

The score is announced with the server’s score first. If the server has won two points and the receiver has won one, the score is 30–15.

The historical origin of the word love for zero is uncertain. One popular explanation links it to the French word l’œuf, meaning egg, because an egg resembles the shape of zero. However, this is a theory rather than a definitively established origin.

What Does Deuce Mean in Tennis?

Deuce occurs when both players reach 40–40 in a game using traditional advantage scoring.

At deuce, a player must win two consecutive points to win the game:

• The first point gives that player an advantage.

• Winning the next point wins the game.

• Losing the next point returns the score to deuce.

Imagine that Player A and Player B are tied at 40–40. Player A wins a point, so the score becomes advantage A. If Player A wins the next point, the game is over. If Player B wins it instead, the score returns to deuce.

This process can continue until one player wins two consecutive points after deuce.

What Does Advantage Mean?

Advantage is the temporary lead gained by winning the first point after deuce.

• Advantage server: The player serving has the advantage.

• Advantage receiver: The player receiving has the advantage.

The advantage does not guarantee victory. The player must win the next point to finish the game.

Some competitions use a no-ad scoring format. In that format, a deciding point is played at deuce instead of requiring a player to win two consecutive points. The exact rules depend on the competition.

Understanding Games and Sets

How Many Points Are Needed to Win a Game?

In traditional advantage scoring, a player normally needs to win at least four points and lead by two points to win a game.

For example:

• 40–0: The player can win the next point to finish the game.

• 40–30: The player needs one more point to win.

• 40–40: The game reaches deuce.

• Advantage: The player needs one more point to win, provided the opponent does not equalize first.

How Many Games Are Needed to Win a Set?

A standard set is normally won by the first player to win at least six games with a lead of two games.

For example, a player who leads 5–4 has not yet won the set. They need to win another game, but the opponent can still equalize.

If the score reaches 6–6 in a set using a tiebreak, the tiebreak usually determines the set winner.

How Many Sets Are Needed to Win a Match?

The number of sets required depends on the competition.

• Best-of-three: A player or team wins the match by winning two sets.

• Best-of-five: A player or team wins the match by winning three sets.

Many professional tour matches use best-of-three sets. Men’s singles at the four Grand Slam tournaments use best-of-five sets, while women’s singles at those tournaments use best-of-three sets.

Always check the competition format rather than assuming every tennis match follows the same structure.

Tennis Tiebreak Rules

A tiebreak is used to decide a set when the score reaches a specified level, commonly 6–6.

How Does a Standard Tiebreak Work?

In a standard seven-point tiebreak, the first player to reach at least seven points with a two-point lead wins.

For example:

• 7–4: The player wins the tiebreak.

• 7–6: The tiebreak continues because the lead is only one point.

• 8–6: The player wins the tiebreak.

• 10–8: The player also wins, assuming the required two-point lead has been achieved.

The players change ends after every six points in a standard tiebreak. Service also follows a special rotation: the first server serves one point, after which players alternate serving two points at a time.

What Is a 10-Point Match Tiebreak?

A 10-point match tiebreak is a deciding tiebreak used in place of a full final set in certain formats. The first player or team to reach at least 10 points with a two-point lead wins it.

Do not confuse this format with the regular seven-point set tiebreak.

Grand Slam Final-Set Tiebreak Rules

The four Grand Slam tournaments introduced a common final-set tiebreak format in 2022. When the deciding set reaches 6–6, a 10-point tiebreak is played, and the winner must lead by at least two points.

For the current official wording and any amendments, consult the ITF Rules of Tennis.

Basic Rules of Playing Tennis

Understanding scoring is only part of following tennis. You also need to know how a point starts, where the ball must land, and what happens when a player makes a mistake.

How a Tennis Point Starts

Every point begins with a serve. The server stands behind the baseline and hits the ball diagonally into the opponent’s service box.

The serve must land inside the correct service box or touch a line bounding that box. A serve that misses the required area is a fault.

A server normally gets two attempts to deliver a valid serve. If both attempts are faults, the result is a double fault, and the opponent wins the point.

What Happens During a Rally?

After a valid serve, players hit the ball back and forth over the net. In ordinary play, each player must return the ball before it bounces twice on their side.

A player loses the point when the opponent:

• Fails to return the ball before it bounces twice.

• Hits the ball into the net without a valid return.

• Hits the ball out of the court.

• Commits a fault that results in the loss of the point.

A ball that touches a boundary line is considered in, provided it lands on a line that forms part of the relevant court area.

What Is a Let?

A let serve occurs when a serve touches the net but otherwise lands in the correct service box. Under the standard rules, that serve is replayed.

A ball touching the net during an ordinary rally is not automatically a let. If it crosses the net and lands legally in the opponent’s court, play continues.

When Do Players Change Ends?

Players change ends according to the competition rules. In a standard game format, they generally change ends after the first game of a set and then after every two games. During a tiebreak, players change ends after every six points.

Specific competition formats may have additional procedures, so the official rules remain the best reference for unusual situations.

The Four Grand Slam Tournaments

The Grand Slams are the four major annual tennis tournaments widely regarded as the sport’s most prestigious events.

Australian Open

The Australian Open takes place in Melbourne and is played on hard courts. It is the first Grand Slam of the calendar year and is known for fast-paced tennis and often hot summer conditions.

French Open

The French Open, also known as Roland-Garros, is held in Paris on clay courts. Clay generally slows the ball and can produce higher bounces, often rewarding patience, movement, and tactical point construction.

Wimbledon

Wimbledon is held in London and is famous for its grass courts and long history. First played in 1877, it is the oldest of the four Grand Slam tournaments.

Grass generally produces a different bounce and pace from clay, making serve placement, quick reactions, and movement especially important.

US Open

The US Open takes place in New York on hard courts. It is the final Grand Slam of the calendar year and is known for its energetic atmosphere and evening sessions.

The four tournaments have their own traditions and operational details, but they share the core rules of tennis. For event-specific scoring and match formats, consult each tournament’s current official rules.

Basic Tennis Shots You Should Recognize

Recognizing the main shots will help you understand a rally and why a player chooses a particular tactic.

Forehand

A forehand is generally hit from the player’s dominant-side position. Right-handed players usually strike it from the right side of their body, while left-handed players typically strike it from the left.

The forehand can be used for powerful attacking shots, controlled rallies, and angled winners.

Backhand

A backhand is hit from the opposite side of the body. Players may use a one-handed or two-handed backhand.

A backhand is not necessarily defensive. Skilled players can use it to generate pace, change direction, create angles, and finish points.

The Serve

The serve starts each point and can be an important attacking weapon.

Common serve types include:

• Flat serve: Usually struck with relatively little spin for pace.

• Slice serve: Uses sidespin to make the ball curve and move away from an opponent.

• Kick serve: Uses spin to produce a higher bounce.

An ace is a valid serve that the receiver does not touch.

Volley

A volley is a shot hit before the ball bounces, usually near the net. Players often use volleys to finish points quickly or take time away from an opponent.

Lob

A lob is a high shot intended to travel over an opponent, particularly one positioned near the net.

Drop Shot

A drop shot is played softly so that the ball lands close to the net on the opponent’s side. It can be effective when the opponent is positioned far behind the baseline.

Smash

A smash is an overhead attacking shot, often used to finish a point after a weak return or a lob.

Singles vs. Doubles: Key Differences

Tennis can be played as singles or doubles.

• Singles: One player competes against one opponent.

• Doubles: Two players form a team against another team of two.

Court Dimensions

The court’s length is the same for singles and doubles, but the usable width differs.

The doubles court includes the alleys along both sides of the singles court.

During a doubles rally, a ball landing inside an alley is valid. However, the serve must land in the diagonally opposite service box, just as in singles.

How Does Doubles Serving Work?

Each doubles team establishes a serving order. Players from the two teams take turns serving games according to that order.

For example, if the serving order is A, C, B, D, then the sequence repeats in that order throughout the set unless the competition’s rules or a permitted correction applies.

Doubles requires coordination, communication, positioning, and teamwork. One partner may serve while the other positions near the net to pressure the opponents.

International Team Competitions

Professional tennis includes international competitions in which players represent their countries rather than competing only for individual titles.

Davis Cup: Men’s International Team Tennis

The Davis Cup is a major international team competition in men’s tennis. National teams compete in ties, with the format depending on the stage of the event.

The official Davis Cup format guide explains its competition structure, including the Finals, Qualifiers, and lower groups.

In some home-or-away ties, a matchup can include up to five matches: two singles matches on the first day, followed by doubles and reverse singles on the second day. The first nation to win three matches wins the tie.

The Finals use a different structure, with eight nations competing in a knockout event. Formats and dates can change from season to season, so check the official Davis Cup website for current details.

Billie Jean King Cup: Women’s International Team Tennis

The Billie Jean King Cup is a major international team competition in women’s tennis. It was originally launched as the Federation Cup in 1963 and was renamed in 2020 to honour Billie Jean King.

The official Billie Jean King Cup format guide explains the different competition levels and Finals format.

The Finals use an eight-team knockout format. Each tie consists of two singles matches followed by a doubles match, and the first nation to win two matches wins the tie.

The competition also includes Qualifiers, Play-offs, and regional groups. Check the official Billie Jean King Cup website for the latest schedules, participating teams, and event rules.

Common Tennis Terms Explained

Frequently Asked Questions

Why does tennis scoring go 15, 30, and 40?

Tennis uses a traditional scoring sequence rather than ordinary counting: love, 15, 30, 40, and game. The historical origin of this system is not fully settled, which is why explanations for the numbers vary.

What does love mean in tennis?

Love means zero points. If the score is 30–love, the first player has won two points while the opponent has won none.

What happens at deuce?

At deuce, both players have reached 40–40 in traditional advantage scoring. A player must win two consecutive points to win the game. The first point creates an advantage, and the next point either ends the game or returns the score to deuce.

How many points are needed to win a tennis game?

In traditional advantage scoring, a player normally needs at least four points and a two-point lead to win a game. If the score reaches deuce, play continues until one player wins two consecutive points.

How many games are in a tennis set?

A standard set is usually won by the first player to win six games with a two-game lead. If the score reaches 6–6, a tiebreak is commonly played, depending on the competition’s rules.

How many sets are played in a tennis match?

Many matches use best-of-three sets, meaning the winner must win two sets. Some matches, including men’s singles at Grand Slam tournaments, use best-of-five sets, meaning the winner must win three sets.

What is the difference between a seven-point and a 10-point tiebreak?

A standard seven-point tiebreak is won by the first player to reach at least seven points with a two-point lead. A 10-point match tiebreak follows the same two-point-margin principle but uses a target of at least 10 points.

What is the difference between singles and doubles tennis?

Singles is played between two individual players. Doubles is played between two teams of two, and the doubles court is wider because the side alleys are included during rallies.

What is a break point in tennis?

A break point occurs when the receiver is one point away from winning the game against the server. Winning the game while receiving is commonly called breaking serve.

Which are the four Grand Slam tournaments?

The four Grand Slams are the Australian Open, French Open (Roland-Garros), Wimbledon, and US Open. They are played on hard, clay, grass, and hard courts respectively.

Final Takeaway

Tennis scoring becomes much easier once you understand the basic sequence: love, 15, 30, 40, and game. Games combine to form sets, and winning the required number of sets determines the match.

Remember these essential rules:

• Traditional scoring uses 15, 30, and 40.

• Deuce requires a two-point advantage in standard advantage scoring.

• A set is commonly won by reaching six games with a two-game lead, or by winning the applicable tiebreak.

• Matches may use best-of-three or best-of-five sets.

• Tiebreak rules vary by format, and the Grand Slam deciding-set tiebreak is played to 10 points with a two-point lead.

• Singles and doubles use different court widths during rallies.

With these basics in mind, you can follow most tennis matches more confidently, understand the scoreboard, and appreciate the tactics behind each point.
