The Top 10 Rules Of Tennis

rules of tennis

Tennis is a sport that has been around since 1873. There are two forms of the sport, called singles and doubles. Singles matches consist of two players competing head to head as they attempt to hit the ball in the boundaries of their opponent's side of the court without the opponent returning the ball before it bounces twice.

The same rules apply for doubles except for the boundaries. However, doubles consist of two players on each team, so the boundaries are bigger giving the players more room to hit the ball on the opponent's side. The added room is called the doubles alley.

1. Coin Toss

tennis coin toss

Before any tennis match begins, the players meet at center court to determine who will serve first and from which side of the court that will be from. The chair umpire will come out to center court and greet both players with a handshake before asking the lower ranked players to call heads or tails. The umpire then proceeds to toss the coin and the winner of the toss has the decision to recieve or serve, or decide which side they want to play on first. If the winner of the coin toss elects to choose a side, the other players will elect if they want to serve or receive first. Most elect to serve first as serving is a huge advantage in tennis. If a coin isn't available, tennis players sometimes use their rackets and spin it using the logo of the racket to denote either up or down (like heads or tails).

2. Serving Rules

Tennis Serving

The beginning of every point in tennis starts with a serve. Players toss the ball in the air and attempt to hit it over the net into the opponent's service box. Players have two service chances to get the ball into the box. If a player misses both serves, they lose the point called a double fault. A let happens if a player hits the ball off the net and it lands in the correct service box. A players' feet must remain behind the service line throughout the serve or a foot fault is called by the chair umpire. In professional matches, a timed clock between serves ensures that points are played within 30 seconds. Prior to this rule, some players would take several minutes to serve between points causing frustration for the opponent as well as the fans. The clock generally starts at the conclusion of a point and counts down from 30 seconds.

3. Player Challenges

tennis player challenges

In tennis there are line judges who call any ball that is out of bounds out by screaming "out" in the middle of the point. They are more often correct than not, but sometimes the play is too fast and they make mistakes. Players have the ability to challenge a call the line judges make. In order to do so, a player must raise their finger or hand and yell out "challenge." They can only do so on the last shot of a rally. Each player has two challenges per set. When a player challenges a call, the chair umpire uses video technology that shows whether the ball was in or not. If the player gets their challenge correct, they retain the same amount of challenges they had. If the player is incorrect they lose the challenge. In the event a set goes to a tiebreak, players receive one additional challenge on top of how many they had remaining. At the beginning of a new set, challenges are reset to two no matter how many challenges the player had remaining in their previous set.

4. Sets/Games

tennis sets games

In most tournaments, matches are played to best two out of three sets. In major tournaments like the Australian Open, Wimbledon, French Open and the US Open, women's tennis matches are best two out of three sets while men's matches are best three out of five sets.

In tennis a player must win six games to win the set. If each player gets six games, a tiebreaker is used to determine the winner of the set. If each player gets five games, a player must win by two games to win the set, which is why you sometimes see set scores that are 7-5 or 5-7.

In order to win a game, a player must win four points before the other player wins four, unless the score hits deuce. The points are called 0, 15, 30, and 40. In a game, "love" means zero. Deuce is when the score is tied at 40-40 also called "40-all". When deuce happens, a player must win by two to win the game. The point is called an advantage or "ad" for short. You'll sometimes hear "ad-in" or "ad-out", which is just short-hand for which player has the advantage. "Ad-in" means the advantage is with the server. "Ad-out" means the advantage is with the returner.

5. Ranking System

The ranking system in tennis is fairly unique. Each player receives a ranking based on how many points they acquire over tournaments throughout the year. Depending on how far a player makes it into a tournament they recieve more points. The champion of a tournament receives the most points while someone who lost in the first round receives the least. Different tournaments have different point systems with the four majors handing out the most points. There are four levels of tournaments in terms of points handed out with #1 being the highest and so forth: 1. Grand Slams, 2. Masters 1000, 3. ATP 500, And 4. ATP 250. Grand slam champions recieve 2,000 points while the other three levels have the amount of points the winner receives in the title. Seeding in tournaments is determined based on world ranking, meaning the higher the seed you are the higher ranked in the world you are. Therefore, it is important for players to compete as often as possible to acquire as many points as possible throughout the season.

6. Tiebreakers

Tennis Tiebreakers

If a tennis match is tied six to six in games in a set, the players are forced to decide the winner of the set through a tiebreaker. Tiebreakers are essentially a longer game. Instead of having 15, 30, 40 scoring, the players play first to win seven points with a margin of two points or more over their opponent to win the tiebreaker and ultimately the set. If the score is tied 6-6 in the tiebreak, they must continue playing until someone wins by two points. In a tiebreak, the person who served the last game to get the set to 6-6 in games will receive the opponent's serve for the first point. Following the first point, the players alternate every two serves and switch sides after every six points. In rare circumstances such as Wimbledon, players continue playing until someone wins by two games. Wimbolden had to change the rule to a maximum score of 12 to 12 in games before playing a tiebreaker due to a match that went on for several days between John Isner and Nicolas Mahut that ended with a 70-68 score in games for the final set.

7. Deuce

tennis deuce

When a game within a tennis match is tied 40-40 in scoring, the terminology for this specific score is called a deuce. When this occurs, players continue playing points until someone wins two points in a row. When the server wins the first point of a deuce, the terminology for the score is called "advantage in." If the player who is receiving wins the first point of a deuce, the terminology for the score is called "advantage out." In certain tennis competitions they don't play deuce scoring, meaning that when a game is tied 40-40, the server gets the choice of what side he or she wants to serve to and that ensuing point determines who wins the game.

8. Doubles/Singles

Tennis Doubles Singles

In tennis there are two forms of competitions: singles and doubles. Singles tennis matches have two players while doubles matches have four players. The same rules apply in terms of how tennis is played, but in doubles the four players alternate serving, meaning that an individual who serves to begin the match doesn't serve again until the 5th game of the set. Additionally, the boundaries of the court are a bit different. In doubles matches, players are allowed to hit the ball in the doubles alley. The reason for this is because there is less space on the court to hit the ball past your opponent when there is more than one of them on the court as there is in doubles.

9. Ball Boys/Girls

If you have watched tennis before you may have noticed people running around the court after the conclusion of a point picking up the ball. These people are assigned ball boys and girls. Ball boys and girls have a few responsibilities. At the conclusion of each point, they must pick the ball up in a timely manner if it's closest to them. Before the next point begins, they are responsible for handing the tennis player who is serving the ball. If the player asks for a towel, the ball boy or girl will be equipped with one and hand it to the player. While a point is going on, the ball boys and girls must remain as still as possible for the purpose of not distracting the players.

10. Chair Umpire

The chair umpire in tennis is the most important person when it comes to making a call or fixing an issue occurring in a match. Chair umpires have several responsibilities. They must watch every point closely and overrule a call from a linesman if they deem their call to be incorrect. Additionally, they announce the score after every point concludes. If a player wants to challenge a call they must ask the chair umpire to do so. Chair umpires are also responsible for controlling the crowd during a match, specifically noise related issues. If a player misbehaves such as smashing a racquette or hitting a ball into the crowd, the chair umpire has the right to issue a warning to the player. If a player continues misbehaving, the chair umpire can ultimately disqualify the player, resulting in their opponent winning the match.


Who serves first in tennis?

In tennis, there is no home field advantage or other factors that dictate who gets to serve first. Instead, in most professional competitions, the first player to serve is decided by a coin toss. That being said, the lower ranked player gets to call which side of the coin they would like prior to the toss. The winner of the coin toss will either choose to receive or serve first, or which side of the court they'd like. If the winner of the coin toss were to choose a side of the court instead of choosing to serve or receive, their opponent will decide who serves first.

How many lets are allowed in tennis?

A let in tennis is when a player serves the ball into the opponent's legal service box, but the ball touches the net on the way. This is different from a fault, because it landed where it was supposed to, but touching the net is not allowed. Because of this difference, players are allowed an unlimited number of lets without being penalized. There have even been instances where players have had four or more lets in a row!

How do you win a tennis match?

In order to win a tennis match, you must win more sets than your opponent. Typically, men's matches are a best of five series while women's are a best of three. The first player to win six games in a set will win the set, as long as they win by two or more games. If a game is tied 5-5, for example, a player will then have to win seven games with a tiebreaker set being played in the event of a 6-6 score. Each game is played up to four points, as long as the first to four has a two point advantage. If not, the game will continue until someone wins by two points.
