Basic Rules of Tennis
The objective of tennis is simple: win more points than your opponent by returning the ball until they are unable to continue the rally. Every point begins with a serve. The server must hit the ball diagonally into the opponent’s service box. Once the return is made, both players can hit the ball anywhere within the singles or doubles court, depending on the format being played.
A player wins a point if their opponent:
- Hits the ball out of bounds.
- Hits the net.
- Allows the ball to bounce twice.
- Misses both serves.
- Commits a rule violation.
Points combine to form games, games combine to form sets, and sets determine the winner of the match.

How Matches Are Won
Most recreational matches and professional tour events are played as the best of three sets. The first player to win two sets wins the match. Some men’s Grand Slam singles matches are played as the best of five sets, meaning a player must win three sets to claim victory.
Court Boundaries
During singles, players use only the inner sidelines. During doubles, the doubles alleys become part of the court, making the playing area wider. Regardless of the format, the baseline forms the back boundary, while the net divides the court into two equal halves.
Serving Rules
Every point starts with a serve, making it one of the most important shots in tennis. The server begins behind the baseline and alternates between the right and left sides of the court after every point. The serve must travel diagonally into the opponent’s correct service box. If the serve lands outside the service box, hits the net without landing correctly, or misses the ball entirely, it counts as a fault. Players receive two attempts to make a legal serve. If both attempts are faults, the result is a double fault, and the receiving player automatically wins the point.
Service Rotation
Players alternate serving after every completed game.
Within a game, the server alternates serving from the deuce court (right side) and the ad court (left side) after every point.
Service Order in Doubles
In doubles, each team chooses a serving order before the set begins. Each player serves one full game before the serve rotates to a member of the opposing team. The same serving order must remain throughout the set.
Faults
A fault occurs when a serve fails to meet the rules. Receiving one fault is not a penalty because players are allowed a second serve. However, if both serves are faults, the server loses the point.
Common serving faults include:
- Serving into the wrong service box.
- Serving into the net.
- Hitting the ball out of bounds.
- Missing the ball while attempting to serve.
- Committing a foot fault.
Double Fault
A double fault happens when both the first and second serves are faults. Double faults immediately award the point to the receiver and are among the most common unforced errors in tennis.
Foot Fault
A foot fault occurs when the server steps on or over the baseline before making contact with the ball. Players must remain behind the baseline until they strike the serve. Touching the line or entering the court too early results in a fault, even if the serve lands perfectly.
Lets
A let is a situation where play is stopped and replayed without either player winning or losing the point. The most common example occurs during the serve. If the served ball touches the net but still lands inside the correct service box, the serve is called a let and must simply be replayed. There is no limit to the number of consecutive lets that can occur. In modern professional tennis, electronic line-calling systems have removed many of the traditional replay situations that were once common during rallies.
Tie-Break Rules
When a set reaches 6-6, a tie-break is usually played to determine the winner of the set. Instead of the traditional 15-30-40 scoring, players earn one point for every rally won. The first player to reach 7 points while leading by at least two points wins the tie-break and the set. If the score becomes 6-6 in the tie-break, play continues until one player gains a two-point advantage.
Serving During a Tie-Break
The player whose turn it is to serve begins the tie-break by serving one point. After that, players alternate serving every two points until the tie-break ends. Players also change ends after every six points to keep playing conditions fair.
Match Tie-Breaks
Some recreational leagues, doubles events, and mixed competitions replace a deciding final set with a match tie-break.
Instead of playing a full set, players compete to 10 points, again needing a two-point advantage to win.
No-Ad Rules
Traditional tennis games require a player to win by two points after reaching deuce. However, some competitions use No-Ad scoring to speed up matches. Under No-Ad rules, once the score reaches 40-40, there is no advantage. Instead, the next point immediately decides the game. In doubles, the receiving team chooses whether the serve will be received from the deuce side or the advantage side before the deciding point is played.
No-Ad scoring is commonly used in:
- Club leagues
- College tennis
- Junior tournaments
- Recreational competitions
- Some doubles events
Although No-Ad scoring creates shorter matches, it also increases pressure because a single point can determine an entire game.
Singles Rules
Singles tennis is played between two players using the narrower singles court. The doubles alleys are not part of the playing area, making movement and shot placement especially important. Each player serves for one full game before the serve rotates to their opponent. During every game, the server alternates between serving from the right (deuce court) and left (ad court). A player wins a point if their opponent fails to return the ball before it bounces twice, hits the ball out of bounds, hits the net, or commits a rule violation.
Because there is only one player covering each side of the court, singles matches often involve longer rallies, greater physical demands, and more strategic court positioning than doubles.
Doubles Rules
Doubles follows the same basic rules as singles but is played by two teams of two players. The main difference is that the doubles alleys become part of the court, creating a wider playing area. Teams usually divide responsibilities, with each player covering one side while working together to control the court. Each team chooses a serving order before the set begins. Every player serves one full game before the serve rotates to the opposing team. Likewise, each team establishes a receiving order that must remain the same throughout the set. Communication is an important part of doubles. Players must coordinate movement, call shots clearly, and decide who will take balls down the middle of the court.

Hindrance Rules
A hindrance occurs when one player interferes with their opponent’s ability to play a point fairly. Intentional hindrance usually results in the player immediately losing the point. Examples include shouting during a rally, deliberately distracting an opponent, or intentionally blocking their path. Unintentional hindrances may result in the point being replayed if the chair umpire determines that neither player gained an unfair advantage.
Common examples of hindrance include:
- A player yelling while the ball is still in play.
- Dropping a racket that distracts an opponent.
- A ball rolling onto the court during a rally.
- Outside interference from spectators or another court.
The purpose of the hindrance rule is to ensure that every point is played under fair conditions.
Code Violations
Professional tennis follows a Code of Conduct that governs player behavior during matches. Players who violate these standards can receive warnings, lose points, lose games, or even be defaulted from the match.
Common code violations include:
- Racket abuse
- Ball abuse
- Audible obscenity
- Visible obscenity
- Unsportsmanlike conduct
- Coaching violations (where prohibited)
- Time violations
- Delaying play
Typical Penalty Progression
| Offense | Penalty |
|---|---|
| First violation | Warning |
| Second violation | Point penalty |
| Third violation | Game penalty |
| Further violations | Default at the umpire’s discretion |
Tournament officials have the authority to increase penalties for particularly serious misconduct.
Tournament Formats
Tennis tournaments can use several different formats depending on the competition.
Single Elimination
The most common format. Players are eliminated after one loss, and the winner advances to the next round until only one champion remains.
Round Robin
Every player competes against every other player in their group. The players with the best records advance to the knockout stage. This format is commonly used at the ATP Finals and WTA Finals.
Team Competitions
Events such as the Davis Cup, Billie Jean King Cup, and United Cup feature national teams competing through a combination of singles and doubles matches.
Best of Three Sets
Most professional tournaments, junior events, and recreational competitions use the best-of-three format.
Best of Five Sets
Only men’s singles matches at Grand Slam tournaments are played as best-of-five sets.
Grand Slam Rules
The four Grand Slam tournaments are the most prestigious events in tennis:
- Australian Open
- French Open
- Wimbledon
- US Open
Although they follow the same basic rules of tennis, there are a few differences compared to regular ATP and WTA Tour events.
Match Format
- Men’s singles: Best of five sets.
- Women’s singles: Best of three sets.
Final Set Tie-Break
All four Grand Slams now use a 10-point match tie-break when the final set reaches 6-6. The first player to reach 10 points with a two-point advantage wins both the tie-break and the match.
Coaching
Off-court coaching rules have evolved in recent years and may differ slightly between tours and tournaments, but players must still follow the tournament’s official regulations.
ATP vs WTA Rules
Many fans assume the ATP and WTA tours use different rules, but the game itself is almost identical.
| ATP | WTA |
|---|---|
| Best of 3 sets | Best of 3 sets |
| Grand Slam men play Best of 5 | Grand Slam women play Best of 3 |
| Same scoring system | Same scoring system |
| Same court dimensions | Same court dimensions |
| Same serving rules | Same serving rules |
The primary differences between the ATP and WTA relate to tournament structure, prize money distribution, ranking systems, and match format at Grand Slam events. The official Rules of Tennis are governed by the International Tennis Federation (ITF), ensuring consistency across both professional tours.
