Common Mistakes in Reading Rules in Badminton and Tennis

The common mistakes in reading racket sports rules in badminton and tennis are more widespread than many people think. Even those who regularly watch or play badminton and tennis often make mistakes in reading the scoring system, service rules, and court boundaries of these two sports. The very fact that badminton and tennis both use rackets and nets leads to the false assumption that their rules are almost identical. Therefore, it is important to know the correct reading of the official rules from the Badminton World Federation and the International Tennis Federation to avoid confusion among players and spectators.

The Source of Confusion in Badminton and Tennis Rules

Badminton has a long history as an official sport under the Badminton World Federation, which established the current Laws of Badminton in 2006 and revised them in June 2016. Before this, badminton used an older scoring system that was not rally-based, where points could only be scored by the server. The major change to rally scoring in 2006, where each rally awards a point to anyone, is one of the main reasons why many still confuse the old and new rules. For tennis, the rules are governed by the International Tennis Federation and the point-game-set system structure remains well-known worldwide.

Mistake #1: Thinking Badminton and Tennis Have the Same Scoring System

This is the most common mistake in reading racket sports rules in badminton and tennis. According to Olympics.com, badminton uses rally scoring: each rally, regardless of the outcome, awards a point to the winner. The first to reach 21 points wins a game, and the match is best-of-three games. If tied at 20-20, a two-point lead is needed; if it reaches 29-29, the next point ends the game at 30 points.

In tennis, according to Wikipedia Tennis, it uses a unique structure: points (love, 15, 30, 40), games, and sets. A set typically requires six games with a two-game lead. Confusion between these two systems leads to incorrect score calculations in both sports.

Mistake #2: Misunderstanding the Service Rules of Badminton and Tennis

The Serve in Badminton

According to Open UGA, in badminton, the serve must be delivered from the correct service court and must cross diagonally (cross-court) to the opponent’s corresponding service court. A common mistake is delivering the serve directly, not diagonally. Additionally, the serve must be hit while the shuttle is below the server’s waist, and the racket must be pointed downward at the time of impact. Another frequent mistake: the false belief that only the receiver can receive the serve, which is true. If the receiver’s partner touches the shuttle before the receiver hits it, it is a fault.

The Serve in Tennis

A major difference that often causes confusion is the two chances to serve in tennis. If the first serve faults, the player can serve again. The second fault gives a point to the opponent, called a “double fault.” In badminton, there is only one chance to serve, and any violation immediately results in a fault that awards a point to the opponent.

“The most dangerous mistake in reading racket sports rules is assuming that the rules of one sport apply to another sport.”

Mistake #3: Confusion in Court Boundaries of Badminton and Tennis

The court boundaries of badminton and tennis are unique and often confused. In badminton, according to Olympics.com, the singles court is 5.18 meters wide, while the doubles court is 6.10 meters. However, the important difference is: for doubles service, the narrower part of the court (singles width) is used, but after the serve, the full width is used. This is one of the most confusing aspects of badminton for beginners.

In tennis, the court width for singles is 27 feet, while for doubles it is 36 feet, according to Wikipedia Tennis. The doubles lines are visible on the tennis court even in singles matches, which can confuse new players or spectators.

Mistake #4: Misreading the “Let” Rule in Both Sports

The term “let” has different meanings in badminton and tennis, and it is one of the common mistakes in reading racket sports rules. In tennis, a “let” on the serve occurs when the ball grazes the net but falls into the correct service box. In this case, the server is allowed to serve again without penalty. In badminton, a “let” (also known as “net cord” in tennis context) can be declared by the referee in various situations such as when there is an interruption in the game or when there is an unclear decision by the referee. In badminton, a shuttle that hits the net during a rally is still played if it crosses; if not, it is a fault of the sender.

Mistake #5: Not Knowing the Correct Service Court in Badminton

The service court system of badminton is one of the most confusing parts for beginners. According to Open UGA, at the start of each game when the score is 0-0, the server serves from the right service court. When the server’s score is an even number (0, 2, 4, etc.), they serve from the right; when it’s an odd number (1, 3, 5, etc.), they serve from the left. Mistakes in the correct service court immediately result in a fault. This is different from tennis where the server switches sides after each point in a service game.

Comparison of Scoring: Badminton vs. Tennis

Comparison of Court Dimensions and Net Heights

The significant difference in net height is one of the often overlooked aspects. The badminton net is higher than the tennis net, explaining why a higher shuttle trajectory is needed in badminton compared to the ball in tennis.

Sports Rules in the Philippines: Badminton and Tennis

In the context of sports in the Philippines, badminton and tennis are both popular sports with active participation from amateurs to professionals. The common mistakes in reading racket sports rules in badminton and tennis are especially noticeable at the barangay and school tournament levels where referees may not be fully versed in the official rules. For those interested in deepening their knowledge of other sports, they can check the Rules of the New Format of the PBA In-Season Tournament for a comparison of how rules are read in different sports.

“The correct reading of the official rules from the BWF and ITF is not only for referees, but for every player and spectator who wants to fully understand the sport.”

Mistake #6: Not Knowing the Fault Rules in Badminton

According to ActiveSG Circle, faults in badminton include: the shuttle hitting the player’s body or clothing, the player touching the net while playing the shuttle, the shuttle landing outside the court, and the serve not being executed correctly. One of the least known fault rules is about the “double hit,” where the shuttle must be hit only once. If the shuttle contacts the racket twice in one swing, it is a fault even if unintentional.

Frequently Asked Questions About Racket Sports Rules

What is the difference in scoring between badminton and tennis?

Badminton uses a rally point scoring system where each rally, regardless of who wins, awards a point. The first to reach 21 points wins a game, and the match is best-of-three games. Tennis, on the other hand, uses a point-game-set system with terminology love (0), 15, 30, and 40, with deuce and advantage when tied at 40-40. These systems are completely different and should not be combined.

How many times can you serve in tennis?

In tennis, the server is given two chances. If the first serve faults (falls in the wrong service box, hits the net and doesn’t cross correctly, etc.), the player can serve again. The second fault is called a “double fault” and awards a point to the opponent. In badminton, there is only one chance, and any service fault immediately awards a point to the opponent.

What does “deuce” and “advantage” mean in tennis?

“Deuce” in tennis occurs when the score is 40-40. In this case, a player must win two consecutive points to win the game. The first point after deuce is called “advantage” for the player who wins it. If the player with the advantage wins again, they win the game; if the opponent wins, the game returns to deuce. In badminton, a similar situation is the 20-20 deuce where a two-point lead is needed.

When is the shuttle “out” in badminton and the ball “out” in tennis?

In badminton, the shuttle is “out” when it falls outside the court lines. In singles, the narrower court is used; in doubles, the full court is used after the serve. In tennis, the ball is “out” when it goes beyond the court lines, including the baseline and sidelines. The lines themselves are part of the “in” area in both sports, so a shuttle or ball hitting the line is considered “in.”

What is the difference between “let” in badminton and tennis?

In tennis, a “let” on the serve occurs when the ball grazes the net but falls into the correct service box, and the serve must be repeated. In badminton, a “let” is called by the referee in various situations such as when the game is interrupted due to external interference. Unlike tennis, there is no automatic “let” in badminton when the shuttle hits the top of the net during a rally.

How can I read the official rules of badminton and tennis?

The official Laws of Badminton can be found on the Badminton World Federation website, while the Rules of Tennis are on the ITF website. For simpler explanations, Olympics.com provides a clear guide for beginners. Reading the primary sources is important to avoid common mistakes.
