“The Complete & Official Tennis Rules Explained
π Introduction to Tennis
Tennis is a racket sport played either 1 vs 1 (singles) or 2 vs 2 (doubles). The objective is simple in concept — hit the tennis ball with your racket so that your opponent cannot legally return it. But the rules and laws governing how points are scored, how matches are played, and how players serve and return are detailed and very specific.
π 1. The Court and Equipment
π’ Court Dimensions
A standard tennis court is a rectangular area measuring:
-
78 feet (23.77 m) long
-
27 feet (8.23 m) wide for singles play
-
36 feet (10.97 m) wide for doubles play
A net divides the court into two equal halves.
π‘ The Net
The net must be:
-
3 feet high (0.91 m) at the center
-
Attached to posts on either side
It divides the court and the ball must pass over this net during play.
π Lines
The court has several lines:
-
Baseline — where players serve from
-
Service lines — which define the service box
-
Sidelines — define the outer boundary
If the ball touches a line and lands inside, it is considered in. If it lands outside or doesn’t touch the line, it’s out.
π 2. The Tennis Ball & Racket
-
Balls must meet size and weight standards set by the tennis governing bodies.
-
Rackets have maximum size specifications, including the head and length. Players must use rackets that comply with rules.
π 3. Starting a Match
Before play begins, a coin toss (or similar) decides:
-
Who will serve first
-
Which side of the court each player/team begins on
Service alternates game by game.
π¦ 4. How Tennis is Scored
Tennis scoring is unique — made up of points, games, sets, and matches.
π Points
A player earns a point when their opponent fails to return the ball within the rules. The sequence of points in a game is:
-
0 points = “Love”
-
1 point = 15
-
2 points = 30
-
3 points = 40
-
4 points = Game (but with conditions)
πΉ Deuce & Advantage
If both players reach 40–40, the score is called Deuce.
From Deuce:
-
The next point won is called Advantage.
-
If the same player wins another point, they win the game.
-
If they lose it, score returns to Deuce.
π Games and Sets
-
A player must win 6 games to win a set, with at least a 2‑game margin.
-
If the set reaches 6–6, a tiebreak is usually played.
In a tiebreak, one player must reach 7 points with a 2‑point lead to win that set.
π Match Formats
Matches can be:
-
Best of 3 sets (most women’s matches)
-
Best of 5 sets (many men’s major matches)
-
Some tournaments use special rules (e.g., shorter sets or tie‑break variations).
πΎ 5. Serving Rules
Serving in tennis is one of the most technical rules in the sport.
π Where and How to Serve
-
The server must stand behind the baseline, between the center mark and sideline.
-
The serve must land in the diagonally opposite service box.
-
The server gets two attempts (first and second serve).
π‘ Let Serve
A let occurs if:
-
The ball touches the net but still lands in the correct service box.
In this case, the serve is retaken without penalty.
π₯ Faults
A serve is a fault if:
-
It does not land in the correct service box
-
The server commits a foot fault (steps on or over the baseline too early)
-
The server misses hitting the ball properly
If the second serve also faults, it’s a double fault and the receiver wins the point.
π‘ 6. Returning the Ball
After a legal serve:
-
The receiver must let the ball bounce once before returning it.
-
During rally, each player can let the ball bounce once, or hit it before it bounces (a volley).
-
If a player fails to return the ball legally, their opponent wins the point.
⚖️ 7. Ball In Play and Points
A ball remains in play until:
-
It bounces twice on one side.
-
It touches anything other than the net or correct court area.
-
A player fails to return it before the second bounce.
If a ball hits the net during a rally (after service) and lands in play, the point continues.
π♂️ 8. Change of Ends
Players must change ends:
-
After the first game, third game, and every odd‑numbered game in each set.
-
After a tiebreak, players often switch ends as part of match protocol.
π§⚖️ 9. Order of Service & Receiving
-
The server and receiver must maintain the correct order of play.
-
In doubles, each player on a team serves in turn.
-
If someone serves out of order, the match continues, but the proper order must resume once discovered.
π 10. Time Rules
There are time‑related rules in modern tennis to ensure play doesn’t stall:
-
A serve clock gives players limited time between points.
-
Warm‑up and change of ends have specific allowed times. These help maintain continuous play.
π§π» 11. Officials & Line Calls
Professional matches use:
-
Umpires — make official decisions
-
Line judges — call in/out
-
Review systems (like Hawk‑Eye) on higher‑level matches
Players may sometimes make calls in amateur settings, but officials’ decisions are final in tournaments.
π 12. Fouls and Penalties
Players lose a point if:
-
The ball hits them or their clothing before a bounce
-
They hit the ball twice without the opponent touching it
-
They interfere with play intentionally
These may seem unusual, but every action on court is governed by the official Laws of Tennis published by the International Tennis Federation (ITF).
π 13. Doubles Rules
-
Doubles use a wider court (including alleys).
-
Serving rotation and receiving order must be agreed before the set starts.
-
Serves and returns must follow the same rules but with teams alternating.
π§ Summary
Tennis is a sport with a simple goal but detailed regulations. From the court measurements and scoring system, to serving rules, faults, lets, and match structure — the laws ensure fair and uniform play worldwide.
