The Basics of Tennis

If you're completely new to tennis, the first thing you need to know is that tennis is played either:

  • One vs one (singles), or
  • Two vs two (doubles)

The objective is to hit the ball over the net and into your opponent’s court in a way they cannot legally return. Points are combined into games, games into sets, and sets into a match.

Court Layout and Equipment

Tennis is played on a standard court. This court is split in two by a net. Each half has lines indicating where the ball must land, with different lines applying to singles and doubles play. These lines indicate whether a shot is in or out, which affects scoring. Don't let the scoring system put you off, though, a tennis coach will keep you right.

The baseline marks the far edge of each player’s side and is where the server stands.
Sidelines determine the width of the court. Inner lines for singles, outer lines for doubles.
The service boxes, formed by the service line and centre service line, determine where serves must land.
The net divides the court, and players must hit the ball over it during every rally.
Essential equipment includes a racket, tennis balls, and non-slip tennis shoes suitable for the court surface.
Different court types (hard, clay, grass) change how the ball bounces, but the rules stay the same.

Objective of the Game

In tennis, your goal is to hit the ball over the net and into your opponent's side of the court so that they cannot return it. Every shot your opponent cannot return scores you a point, provided it was a legal shot. Beginners should start by making consistent contact with the ball and keeping it within the lines.

Hit the ball into the opponent’s court before it bounces twice on your own side.
Keep your shots inside the lines. If the ball lands out, your opponent wins the point.
Continue rallies until one player cannot legally return the ball.
Win enough points to win games, and enough games to win the set.
Most beginner matches follow a simple format: best-of-three sets.

Scoring System in Tennis

The trickiest part of tennis is how points are scored. This system doesn't seem obvious at first because it's based on a clock face, but instead of counting points in a 1, 2, 3 sequence, it uses its own unique scoring system. The scoring system originated in France, but you'll find tennis coaches from Sydney to New York using it, as tennis is a global sport.

TermMeaning / Point Value
Love0 points
151 point
302 points
403 points
Deuce40–40 players must win by 2
AdvantageOne point ahead after deuce
GameWinning the fourth point with a 2-point margin
SetFirst to 6 games with a 2-game margin
TiebreakerSet-deciding game at 6–6 usually to 7 points win by 2
MatchBest of 3 or best of 5 sets depending on format

Points, Games, and Sets

Players in a tennis match earn individual points. These points determine who wins each game. Tennis goes love, 15, 30, and 40 for point totals. A player has to be ahead by two won points to win the game, which is why there are rules like deuce.

compare_arrows
Deuce

Deuce is the score at 40–40. From deuce, a player must win two consecutive points to take the game. If the player with advantage loses the next point, the score returns to deuce.

A game starts at love-love, which means each team scores zero points.
Points progress as 15, 30, 40, then the game if the player is ahead by two.
If both players reach 40-40, this is deuce, meaning the game continues until a player leads by two.
Winning enough games within a set gives players the chance to win that set.
Players alternate serving each game, which affects the score announcements.
call_made
Advantage

The advantage is the one-point lead after deuce. If the player with advantage wins the next point, they win the game. If they lose it, the score goes back to deuce. The chair or players may call it "Advantage server" or "Advantage receiver."

Winning a Set and Match

A set is won by the first player who wins six games by a margin of two. If the score is 5-5 (each player/team having won 5 games), they continue until one reaches 7-5. However, if the score reaches 6-6, it's common for a tiebreaker to decide the set. Some tournaments use alternate rules.

A standard set is won at 6 games to 4, or 7 games to 5.
Beginners usually play best-of-three sets, meaning the first to win two sets wins the match.
Professional men in Grand Slam tournaments often play best-of-five sets.
You must win each set by at least two games unless a tiebreak applies.
Set formats vary slightly by tournament and sometimes by event category.

Tiebreakers

The tiebreaker only occurs when the score is 6-6 in a set. Rather than the usual tennis scoring system, they count 1, 2, 3, etc. When one player reaches 7 points with a margin of two, they win. In tiebreakers, the serve alternates in a special pattern.

Most tiebreakers are played to 7 points, with a 2-point win.
The first server delivers one serve, then players alternate serving two points each.
Players change ends every six points during the tiebreak.
Winning the tiebreak counts as winning the set by a score of 7–6.
Some tournaments use extended tiebreak formats, such as first-to-10 points.
format_list_numbered
Tiebreaker

A tiebreaker decides a set tied at 6–6. Players race to 7 points and must win by 2. Serve alternates after the first point, then every two points, and players change ends every six points.

Serving Rules

Serving is a key part of tennis since every point starts with a serve, and while you can start playing tennis without learning to serve properly, it's something that you'll cover early in your lessons. There are specific rules for serving, and a legal serve is required to put the ball into play. Beginners will need to learn how to serve and understand how serving works so they know when a point starts, when a fault occurs, and how players alternate service during the game.

Serve Begins the Point

The Server Starts the Rally

Every point begins with a legal serve struck diagonally into the opposite service box. The server alternates sides (right, then left) for each serve within a game. A valid serve puts the ball into play and starts the rally.

Rally

Players Exchange Shots

Once the serve is returned, both players rally by hitting the ball back and forth over the net. The ball must bounce only once on each side unless it is volleyed. Players aim to force an error or hit an unreturnable shot.

Point Ends

Point Decided by Error or Winner

A point ends when the ball bounces twice, is hit into the net, lands out of bounds, or a player commits a violation. The winner of the point earns the next score step (15, 30, 40, game).

Starting a Game

Each tennis game starts with a player serving. This player continues to serve throughout the game, starting every point. The server has to stand behind the baseline and between the centre mark and the sideline. They cannot step on the line before hitting the ball, and the serve must travel diagonally into the service box.

The server begins each game and continues until that game ends.
Players alternate serving games throughout the set.
A legal serve must land in the opposite service box.
Serves must be hit behind the baseline without touching it.
Players switch serving sides after every point.
clear
What Is a Foot Fault?

A foot fault occurs when the server steps on or over the baseline before making contact with the ball. Even a toe touching the line during the serve results in a fault. Repeated foot faults can be penalised in officiated matches.

Let Serves

A let serve is when the ball touches the net during the serve but still lands in the correct service box. The point doesn't begin, and the server retakes their serve without a penalty. Let serves are common in tennis and reflect the game's overall fairness, ensuring that neither player has an unfair advantage due to an unpredictable deflection off the net.

A serve that touches the net and lands in the correct box is a let.
The server repeats the serve with no penalty.
A ball that hits the net and lands out is still a fault, not a let.
Let serves can happen on both first and second serves.
Players call a let quickly so the point does not continue by mistake.

In-Play Rules

When the ball is in play, both players follow a simple set of rules. The rules determine whether the ball is still active, when a point ends, and what actions are allowed. Understand these, and you can start playing tennis.

Singles vs Doubles Differences

Singles and doubles have basically the same rules, but the court and player positions change. Singles tennis uses a narrower configuration, whereas doubles involves more teamwork and strategic positioning at the net. The main difference is the "tramlines" used in singles and doubles tennis. In addition to all the other benefits of tennis, the fact that you can play with four people or two people makes it quite accessible.

Singles

  • Only two players: one vs one
  • Uses the inner sidelines (narrower court)
  • Requires more movement, speed, and precision
  • Serves must land in the standard diagonal service box
  • No partner. Players must cover the entire court alone
  • Strategies focus on baseline rallies, placement, and endurance

Doubles

Four players: two vs two

Uses the outer doubles sidelines (wider court)

Emphasises teamwork, positioning, and net play

Only the server’s partner may be positioned at the net

Serves and returns often lead to faster exchanges

Common tactics include poaching, forming walls, and strong net pressure

Ball in Play

In tennis, once a legal serve has been made, the ball is in play until a point is scored. Players can hit the ball before it bounces a second time on their side, either before or after it bounces once. The point continues until the ball lands out of the court or hits the net.

A ball that lands on any part of the line is considered in.
Players may volley the ball as long as it is not the serve return.
The ball remains in play until it bounces twice or a player makes an error.
Players must allow the serve to bounce before returning it.
Shot selection often determines who controls the rally.

In or Out?

In tennis, any part of the ball that touches any part of the line is considered in. Shots landing fully outside all boundary lines are out. The net, posts, and singles sticks are not considered “in” unless the ball passes cleanly over the net and lands inside the lines.

Double Bounces

A double bounce is how every point ends. If the ball bounces twice on a particular player's side of the court without being legally returned, the opponent wins the point. Players in tennis take turns trying to hit the ball into their opponent's half of the court, so they can't do the same. The game is all about choosing the shots that will make returning the ball as difficult as possible for your opponent. Whether you're taking tennis lessons in Melbourne, Sydney, Perth, Adelaide, or Brisbane, your coach can show you how to make smarter shot choices.

The ball may bounce once, but a second bounce ends the point.
Players lose the point automatically if the second bounce occurs.
Volleys prevent bounces entirely and are often used near the net.
Low, fast shots are more likely to force a double bounce.
Court positioning affects how easily a player can reach the ball.

Net Play

The net is a key part of tennis. When players move forward to attack short balls or finish points, they may move closer to the net. They're allowed to swing their racquet over the net, but they're not allowed to touch the net. There are strict rules to ensure there's no interference from the other player.

Players cannot touch the net, posts, or opponent during a point.
A follow-through may legally cross over the net if the initial contact was on the correct side.
Hitting the ball before it crosses the net into your side is not allowed.
Net players often use volleys and overheads to end points quickly.
Spin can cause the ball to travel back toward the net after bouncing.
hdr_weak
Reaching Over the Net

You may legally reach over the net only if the ball has already bounced on your side and is spinning or moving back toward your opponent’s side. You cannot touch the net, interfere with the opponent, or hit the ball before it crosses into your side.

Common Violations and Penalties

In tennis, a violation occurs when a player performs an action that breaks the rules. This can include incorrect service, illegal contact with the net, or misconduct. Penalties make the game fair for all players.

A foot fault occurs when the server steps on or over the baseline before hitting the ball.
Double faults give the opponent a point if both serve attempts fail.
Hitting the ball out results in the opponent winning the point immediately.
Touching the net with the racket, body, or clothing during a point ends the point in favor of the opponent.
Hindrance occurs when a player distracts the opponent, such as speaking or shouting during a rally.
Illegal contact happens when the ball hits the player, their clothing, or anything other than the racket.
Time violations may occur in umpired matches when players take too long between points.

Special Formats and Variations

Once you understand the basics of tennis, you can start looking at some of the nuances. Some tournaments and events use alternative scoring systems and match formats. These exist to speed up matches, create more exciting matches, or simplify competitions for different levels. Given that the cost of tennis can be a barrier for some, these formats help make the sport more accessible and economical.

Tie Break Tens

Tie Break Tens is a format in which players aim to reach 10 points first. This is a format common to exhibitions and social competitions. It's quicker than a traditional set.

The format is a single race to ten points, win by two.
Serve alternates in the same pattern as a regular tiebreak.
Matches are shorter and easier for beginners to follow.
This format is commonly used for informal events and entertainment matches.
Players must maintain focus because rallies finish quickly.

No-Ad Scoring

No-ad scoring is when games are decided by a single point rather than using deuce. When players reach three points each, the game is decided by a single point. It's a higher-pressure version of the original format.

Games reach a deciding point at 3–3 instead of entering deuce.
The receiver chooses whether to play the serve to the right or left service box.
The winner of that single point wins the game outright.
Matches move faster and are easier to schedule in tournaments.
No-ad scoring is used in some professional doubles events and club formats.
