Tennis is a sport loved by millions around the world. It is played on courts, with rackets and a small yellow ball. But for many, the rules can seem complicated at first. If you want to enjoy the game, either as a player or a fan, understanding the basic rules of tennis is essential.
This guide explains everything you need to know in simple, clear language. From how points are scored to common mistakes, you’ll learn the foundation of tennis—so you can follow or play with confidence.
The Tennis Court And Equipment
To understand tennis, you must first know about the court and the equipment used. Tennis courts can be made of grass, clay, or hard surfaces. The size of the court is always the same for singles and doubles, but the playing area changes slightly.
The court is 23. 77 meters (78 feet) long and 8. 23 meters (27 feet) wide for singles matches. For doubles, the width increases to 10. 97 meters (36 feet). The net stands in the center, 0. 914 meters (3 feet) high.
Players use a racket, which is usually about 27 inches (68.58 cm) long. The ball must be yellow or white, and it weighs between 56.0–59.4 grams (1.98–2.10 ounces). Most balls are now yellow, as they are easier to see during play and on television.
Key court features include:
- Baseline: The line at the back of the court
- Service box: Where serves must land
- Sidelines: Mark the side boundaries for singles and doubles
- Net: Divides the court
Court Types Comparison
Here’s a comparison of the main court surfaces:
| Surface | Speed | Bounce Height | Common Tournaments |
|---|---|---|---|
| Grass | Fast | Low | Wimbledon |
| Clay | Slow | High | French Open |
| Hard | Medium | Medium | US Open, Australian Open |
Each surface changes the way the game is played. For example, clay courts slow the ball and produce a higher bounce, favoring baseline rallies. Grass courts, like those at Wimbledon, are faster and the ball stays low.
Scoring System In Tennis
Tennis uses a unique scoring system. Instead of counting “1, 2, 3, 4,” points are counted as 15, 30, 40, and game. This can be confusing for beginners, but it becomes natural with practice.
How A Game Is Scored
- 15: First point won
- 30: Second point
- 40: Third point
- Game: Fourth point, if leading by two
If both players reach 40, it is called deuce. A player must then win two points in a row: the first is called advantage, the second wins the game.
How A Set Is Won
A set is won by the first player to win six games, but they must lead by two games. If the score reaches 5-5, play continues until one player is ahead by two games (7-5, for example). If it reaches 6-6, a tiebreak is played.
How A Match Is Won
A typical match is played as best of three or five sets. Most men’s Grand Slam matches are best of five; all women’s matches and regular matches are best of three. The first player to win the required number of sets wins the match.
Example Of A Tennis Scoreboard
| Player | Set 1 | Set 2 | Set 3 | Games (Current Set) | Points (Current Game) |
|---|---|---|---|---|---|
| Player A | 6 | 4 | — | 2 | 30 |
| Player B | 3 | 6 | — | 3 | 15 |
This scoreboard shows Player A won the first set, Player B won the second, and they are playing the third set.
Basic Rules Of Serving
Serving is how each point starts. The rules for serving are strict, and breaking them can cost you points.
- Who serves first: At the start of the match, a coin toss decides who serves first.
- Serve from behind the baseline: The server must stand behind the baseline and between the center mark and the sideline.
- Serve into the correct box: The server aims diagonally across the court, into the service box.
- Two tries: The server has two chances (first and second serve). If both are missed, it is called a double fault, and the receiver wins the point.
- Let serve: If the ball touches the net but lands in the correct box, it is a let and the serve is retaken.
- Change sides: After each game, players change sides of the court to balance any wind or sun advantage.
Common Serving Mistakes
Beginners often step on or over the baseline before hitting the ball. This is called a foot fault and loses the point. Another mistake is serving into the wrong box or missing both serves.
Rules For Receiving The Serve
The receiving player must be ready before the server hits the ball. The receiver stands behind the baseline and can return from any position.
- The return must land within the singles or doubles court, depending on the match.
- If the receiver is not ready, they may raise their hand or signal to the server to wait.
- If the serve is out, the receiver should call it “out” clearly.
Receivers should not distract the server or move during the serve.
How Points Are Won
Points are won in several ways:
- Ball bounces twice: If the ball bounces twice on the opponent’s side, the point is lost.
- Ball goes out: Hitting the ball outside the court lines loses the point.
- Net faults: If the ball hits the net and does not go over, the point is lost.
- Double fault on serve: Missing both serves gives the receiver the point.
- Opponent cannot return: If the opponent cannot hit the ball before it bounces twice, you win the point.
Sometimes, a player will win a point by hitting an ace (a serve that is not touched by the receiver) or a winner (a shot that cannot be returned).
Example: Ace And Winner
- If Player A serves and Player B does not touch the ball, it is an ace.
- If Player A hits a fast shot to the corner and Player B cannot reach it, that is a winner.
Rules For Rallies
A rally is when the ball is hit back and forth after the serve. There are a few key rules:
- The ball can only bounce once on your side.
- Players may hit the ball before it bounces (volley), except on the serve.
- The ball must cross the net and land in the correct court.
If the ball touches the net during a rally but lands in, the point continues. If it lands out, the point is lost.
Let And Hindrance Rules
A let is a situation where the point is replayed. It usually happens if:
- The serve touches the net but lands in.
- There is a distraction, like a ball rolling onto the court.
- The umpire or a line judge stops play for any reason.
Hindrance means distracting your opponent on purpose, like yelling or waving. This is not allowed and may result in losing the point.
Doubles Rules
Doubles tennis has its own rules, but the basics are similar. The main differences:
- The court is wider, using the doubles sidelines.
- Partners take turns serving.
- Communication is key—players must decide who will return which balls.
In doubles, good teamwork is often more important than individual skill.
Doubles Court Vs. Singles Court
| Type | Court Width | Sidelines Used | Team Size |
|---|---|---|---|
| Singles | 8.23 m (27 ft) | Inner | 1 per side |
| Doubles | 10.97 m (36 ft) | Outer | 2 per side |
Tiebreak Rules
When a set reaches 6-6, a special game called a tiebreak decides the winner of the set. The first player to reach 7 points wins the tiebreak, but they must lead by at least 2 points. If the score is 7-6, play continues until one player leads by two.
During a tiebreak:
- Players serve in a special order: The first server serves one point, then each player serves two points at a time.
- Players switch ends every six points.
- The winner of the tiebreak wins the set.
Tiebreaks add excitement and pressure, testing a player’s nerves and skill.
Change Of Ends And Rest Periods
Players change sides of the court after every odd-numbered game (for example, after 1, 3, 5 games). This keeps the match fair, as sun and wind can affect play.
Between games, players are allowed a 90-second rest. After each set, there is a longer break, usually two minutes. These breaks are important for players to recover, drink water, and plan their next moves.
Ball In Or Out: Line Calls
A point is only won if the ball lands inside the court lines. If any part of the ball touches the line, it is considered in. If the ball is outside the lines, it is out.
Players or line judges make the call. In professional matches, special systems like Hawk-Eye are used to review close calls.
Common Line Call Scenarios
- Ball lands on the line: In
- Ball lands outside the line: Out
- Ball touches net, then lands in: Play continues
Players can ask for a review if they disagree with the call, but only in top-level matches with electronic review systems.
Code Of Conduct: Behavior On Court
Tennis values sportsmanship and fair play. Players are expected to:
- Respect their opponents, umpires, and line judges
- Avoid using bad language or throwing rackets
- Not receive coaching during play (except in some leagues)
Breaking these rules can lead to warnings, loss of points, or even being disqualified.
Clothing And Equipment Rules
Most tournaments have specific rules about clothing. For example, Wimbledon requires players to wear almost all white. Players must also use approved rackets and balls.
Wearing non-marking shoes is important, especially on hard or indoor courts, to avoid damaging the surface.
Common Tennis Terms Explained
Learning tennis means understanding some unique words:
- Deuce: Both players have 40 points; must win two in a row to win the game.
- Advantage: The point after deuce, showing who is ahead.
- Love: Means zero points (for example, 40–love means 40–0).
- Volley: Hitting the ball before it bounces.
- Ace: A serve not touched by the receiver.
- Double fault: Missing both serves in a row.
- Break point: When the receiver can win the game on the next point.
- Match point: A point that, if won, ends the match.
Key Strategies Beginners Should Know
Understanding the rules is important, but strategy can help you win more points.
- Serve deep: A deep serve pushes your opponent back, making returns harder.
- Aim for corners: Hitting to the sides makes your opponent move more.
- Change pace: Mix fast and slow shots to keep your opponent guessing.
- Move your feet: Stay ready and balanced for each shot.
Many beginners forget to recover to the middle of the court after each shot. This makes it easier for your opponent to hit past you.
Common Mistakes And How To Avoid Them
Starting out, players often repeat the same errors:
- Not watching the ball: Always keep your eye on the ball until you hit it.
- Poor footwork: Good movement is as important as a strong swing.
- Trying to hit too hard: Focus on control before power.
- Standing too close or far: Find the right spot behind the baseline for your skill and style.
Another mistake is not knowing the score or losing focus during long rallies. Practice calling the score out loud and staying calm.
What Happens If Rules Are Broken?
If you break a rule, there are clear consequences:
- Foot fault: Loss of point or serve.
- Double fault: Loss of point.
- Hindrance: Loss of point.
- Misconduct: Warning, point penalty, or disqualification.
In friendly matches, players often give warnings first. In tournaments, umpires are strict.
Rules For Wheelchair Tennis
Wheelchair tennis follows most of the same rules, with some changes:
- Players are allowed two bounces of the ball; the second can be outside the lines.
- The rest of the game is the same as in standard tennis.
This makes tennis accessible for more people and is a growing part of the sport.
Tennis For Kids And Beginners
For children, courts and equipment are smaller and lighter. The ITF’s “Tennis Play and Stay” program uses smaller courts, shorter rackets, and softer balls. This helps kids learn and enjoy the game from an early age.
How To Start Playing Tennis
If you want to start playing tennis, you need:
- A racket and tennis balls
- Access to a court
- Comfortable sports clothing and non-marking shoes
Many clubs offer beginner lessons, and you can find friends or coaches to practice with. It is never too late to start playing tennis.
Major International Rules Organizations
The International Tennis Federation (ITF) is responsible for the main rules of tennis. The rules are updated regularly and used worldwide. Other important organizations include:
- ATP (Association of Tennis Professionals) for men’s tennis
- WTA (Women’s Tennis Association) for women’s tennis
- USTA (United States Tennis Association) for tennis in the US
These groups organize the biggest tournaments and keep the sport fair and exciting.

Frequently Asked Questions
What Happens If The Ball Hits The Net During A Serve But Still Lands In?
If the serve touches the net but still lands in the correct service box, it is called a let. The server repeats the serve with no penalty. There is no limit to the number of lets on a serve.
How Many Sets Are Played In A Professional Tennis Match?
Most professional matches are best of three sets. In men’s Grand Slam tournaments, matches are best of five sets. The first player to win the required number of sets wins the match.
Can You Hit The Ball Before It Bounces In Tennis?
Yes, you can hit the ball before it bounces, which is called a volley. The only exception is on the serve—you must let the serve bounce before returning it.
What Is A Double Fault In Tennis?
A double fault happens when the server misses both their first and second serve attempts. The receiver then wins the point.
What Is The Difference Between Singles And Doubles In Tennis?
Singles is played one-on-one, using the inner sidelines. Doubles has two players per team and uses the full court, including the outer sidelines. Doubles also involves more teamwork and communication.
Tennis is a wonderful sport with clear rules and deep traditions. By learning the basic rules of tennis, you open the door to a lifetime of enjoyment—on the court or as a fan. With practice and experience, these rules become second nature, allowing you to focus on skill, strategy, and fun.
Whether you play for competition or health, understanding the basics gives you a strong foundation for success.
