Tennis is an incredibly interesting sport with a long and rich history, many rules, and many fans and players. Therefore, there is much to tell about this great sport.
In this article, you will find the 80 most interesting tennis facts found on the internet. This is the perfect article to increase your knowledge about tennis in a fun way.
Long before the lawn tennis that we know and play today became a thing, people played Jeu de Paume.
It was a French game that is similar to tennis today, except for the fact it used to be played with bare hands instead of a racket.
This Jeu de Paume, which means the game of the hand, eventually evolved into ‘royal tennis’ or ‘real tennis,’ which then became lawn tennis.
Back in 2012, Sam Groth hit the fastest serve ever. This serve was 163.7 miles per hour or 263.4 kilometers per hour.
However, this serve is never officially recognized by the ATP.
The fastest serve recognized by the ATP was the serve of John Isner in 2016. This serve was as fast as 157.2 miles per hour, or 253 kilometers per hour.
In 1988, the final of Roland Garros was not nearly as long as you would expect of a final.
In only 34 minutes, Steffi Graf beat her opponent Natasha Zvereva 6-0 6-0.
This was not the shortest tennis match ever, but it is the shortest Grand Slam final ever played.
Grunting, some players love it, and other players hate it. Maria Sharapova is a well-known grunter, but she is not the loudest.
The loudest grunt of 109 decibels was by Michelle Larcher de Brito.
One hundred nine decibels is louder than a small aircraft landing, an ambulance siren, or a lion’s roar.

If your opponent hits a ball and you are confident it won’t stay between the lines, make sure you let it bounce before you touch it.
If the ball touches your clothes, shoes, or hand before it touches the ground, the point is for the opponent.
In 1875 the rectangular court that we know nowadays was introduced.
Before this time, tennis courts were shaped like an hourglass.
The tennis court is 78 feet (23.77 meters) long, but the width depends on the type of game.
For singles, the court is 27 feet (8.23 meters) wide. For doubles, the court is 36 feet (10.97 meters) wide.
The net needs to have set measurements so that no player will experience benefits or disadvantages due to small differences in measurements.
Wimbledon has been played on grass ever since the tournament’s first edition, and this has never changed.
Nowadays, the US Open takes place on hardcourt, but this wasn’t always the case.
It used to be played on grass at the beginning, then on clay from 1975 to 1978, and eventually on hardcourt.
Although the origin of the scoring system in tennis is lost in time, it is commonly believed that it is based on the clock.
45 would be too long to say, so that is why it’s 15-30-40 instead of 15-30-45.
With tennis, it’s about who wins three or five sets first. It doesn’t matter how long this takes.
In 2010 at Wimbledon, this resulted in a match between John Isner and Nicolas Mahut that lasted 11 hours and 5 minutes.
The final score was 6-4, 3-6, 6-7, 7-6, 70-68, and they played a total of 183 games.
In 1986 at Wimbledon, yellow tennis balls were introduced to make the sport easier to follow for spectators.
If a player manages to win all four Grand Slam tournaments in their career, they are said to have won a Career Grand Slam.
So far, there are eight men and ten women in singles who have completed a Career Grand Slam.
The four Grand Slams are US Open, Wimbledon, Australian Open, and Roland Garros. These four Grand Slam tournaments are the most important tournaments in tennis.
They take place in New York, London, Melbourne, and Paris.
Serena Williams is currently the player with the most Grand Slam titles won. She managed to win a Grand Slam 23 times.
Björn Borg is a name that pretty much every tennis lover has heard of. With a percentage of 89.2, he has a better win-loss ratio than anyone else.
Still, he is closely followed by Rafael Nadal, Novak Djokovic, and Roger Federer.
Tennis is one of the most popular sports in the world. There are approximately 87 million players.
This means that about 1.17% of the world’s population plays tennis.
Roland Garros is one of the four Grand Slam tournaments. It is played on clay, a surface that Rafael Nadal loves.
He has won this Grand Slam thirteen times, more than any other player has won any Grand Slam.
Since 1992 players with a disability can compete for a gold medal as well at the Paralympic Games.
Tenez means to take heed.
There are also rackets available at other lengths, such as 27.5 inches (69.85 cm) or 29 inches (73.66 cm).
Rackets for children are usually between 21 and 26 inches (53.34 and 66.04 cm) long.
The strings in a tennis racket can be made from different types of materials.
The strings can be made of cow intestines, facilitating increased power.
Synthetic strings are often made of nylon, which is cheaper and more common among amateur players because of its all-round performance.
Tennis balls have to meet a couple of requirements as well.
The diameter of the ball has to be between 2.58 to 2.70 inches, which is 65.41 and 68.58 mm. There is a set weight range of 1.98 oz (56.0 grams) to 2.10 oz (59.4 grams).
The only line that is allowed to exceed this width is the baseline. The baseline can be up to 4 inches (10.16 cm) wide.
Although in reality, the baseline is usually as wide as the other lines.
Tennis balls can wear out quite quickly, which is why a ball change occurs every nine games.
The first ball change takes place after seven games since those balls are also used for the warm-up.
An exception is made at the beginning of a tiebreak. In this case, the ball change will wait until the second game of the next set.
In tennis, it is not allowed to hold your racket over the net, so it is on your opponent’s side of the court.
There is one exception, though. When your opponent hits a shot with so much effect, it bounces on your side but moves so far back that the second bounce would be on their own side.
This is the only situation in which you are allowed to hit the ball on your opponent’s side.
There are several stances in tennis, such as the neutral stance and the closed stance.
The open stance is the most common. An open stance means the player stands parallel to the net and allows for plenty of torso rotation.
These eight shots are the serve, forehand, backhand, volley, half-volley, overhead smash, drop shot, and lob.
King Louis X is known as the first tennis player ever because he is the first person from whom we have proof of playing tennis.
This is because he died shortly after a game of tennis, of which there is written evidence.
Although it is said he died of pneumonia after drinking wine to cool down from an intense game of tennis, historians question this and say it’s more likely someone poisoned his wine.
The United States National Lawn Tennis Association is the oldest nationwide tennis association in the world.
The association was formed to clear up rules and organize tournaments.
There has been only one major change of rules since the ITF established the rules in 1924. In 1971, the tiebreak was first included in tennis. This happened at Wimbledon.
Before that, a tiebreak was not part of the official tennis rules yet.
A tweener is when a player hits the ball in between their legs. Several players try and execute this trick shot in exhibition matches, as it’s a real crowd-pleaser.
In actual matches, it is often used as a last resort.
Not including multi-purpose arenas, the Arthur Ashe Stadium in New York is the biggest tennis stadium in the world.
This is where many US Open matches occur.
The stadium is named after the first tournament winner: Arthur Ashe. The stadium can hold over 23.000 people.
Rafael Nadal learned to play tennis with his left hand because it can cause a real inconvenience for right-handed players, which most players are.
It can be a little confusing if someone uses the other hand, making the side that would usually result in forehands now result in backhands and the other way around.
It also allows him to make the ball whirl so that it is difficult for right-handed players.

Back in 2007, the ultimate exhibition match took place between Rafael Nadal, the king of clay, and Roger Federer, the king of grass.
The court for this match was made of clay for one side and grass for the other.
The players had to change shoes every time they changed sides. Eventually, Rafael Nadal ended up winning.
Although playing in the cold or rain is no fun either, in 2007, the Australian Open reached temperatures that are no fun to play in either.

In comparison, the hottest day at Wimbledon ever was in 2015, when temperatures reached 98 degrees Fahrenheit (36.7 degrees Celsius).
Ivo Karlović has hit a total of 13.728 aces in his career. John Isner has the second most aces with 13288 aces, and Roger Federer has the third most career aces with a total of 11452 aces.
Both Venus Williams and Serena Williams are big names in women’s tennis. Venus has seven Grand Slam titles (singles), and Serena has twenty-three Grand Slam titles (singles).
Besides that, they were the fifth pair ever to complete a Career Doubles Grand Slam, and they even managed to complete a Career Doubles Golden Slam.
The exact reason for this is not known. But it is believed to be related to the status of fruit as a desirable product with a high class when Wimbledon was first hosted.
There was, however, a period in which tennis was not an Olympic sport anymore.
In 1924 the sport was no longer part of the Olympic Games, but this changed again in 1988.
The reason for this break is because of disagreements between the International Olympic Committee and the International Lawn Tennis Federation about when a player was considered to be a professional and when they were an amateur player.
If a player hits aces only when serving, and their opponent makes double faults at every point they are serving, a player could win by only hitting the ball twelve times.
This is obviously a very unrealistic scenario, but it’s fun to imagine.
A bagel means the player has lost a set without winning any games, meaning the score of that set is six against zero.
For the Australian Open, it was Rodney Heath. For the French Open, it was H. Briggs; for Wimbledon, it was Spencer Gore; and for the US Open, it was Richard Sears.

To play, you have to be among the best, though.
You can enter through having a high ranking, qualifying yourself through matches, or getting a wild card.
Tennis balls don’t get recycled into new balls very often.
Over the past few years, there has been more awareness of the importance of recycling, so there is progress being made.
Examples of recycling projects are Project Green Ball, which has been converting tennis balls into floors, and the ABN AMRO World Tennis Tournament which has turned balls into shoes for the ball kids.
When you reach 5-5 in games, the first one to get six games does not win. They have to play until it’s 7-5.
If the score becomes 6-6, the person who gets to 7-6 first does not win. They have to play until 8-6, and so on.
The only exceptions for this are tiebreaks.
When the score in a set reaches 6-6, most tournaments nowadays have implemented the tiebreak. It is especially popular in amateur tennis.
A tiebreak is won by the player who reaches 7 points first, and the players take turns serving.
There must be at least a two-point difference in the tiebreak; otherwise, play will continue until it does.
The US Open has a conventional tiebreak. The Australian Open does a tiebreak that doesn’t end at seven but at ten.
Wimbledon does a conventional tiebreak but only after the set has reached 12-12 in games. Roland Garros has no tiebreak and lets the players play until there is a winner.

It helps children with their hand-eye coordination and practicing the technique behind their strokes.
The ball kids at the US Open get paid an hourly wage, but many of them cannot even be considered kids anymore.
People between the ages of 14 through 65 join the try-outs to get selected to be a ball kid.
Ball kids are usually between 12 and 17 years old at the other Grand Slams.
If a serve hits the net and then lands in the service box, the point is not considered faulty nor valid.
The point gets replayed without the server losing one of his service turns.
For Grand Slams, the lucky loser gets randomly picked from the best performing qualifiers who did not manage to get into the tournament because they lost their qualifying match.
A split step is when a receiving player makes a small jump the moment their opponent hits the ball.
Because of this split step, they are able to move in the direction of the ball quicker, and it keeps them alert.
There are regular-duty balls made for soft clay courts and indoor courts. Extra-duty tennis balls are perfect for hard courts, especially outdoors.
Grass court balls are made for grass courts, obviously. Hi-altitude balls are made for altitudes of 4000 feet or higher. Normal balls aren’t fit for these heights.
It is not uncommon for players to need a second racket during practice or a match.
Sometimes the strings of a racket break because they need replacement or the way the ball is hit.
It would be a shame to be forced to forfeit a match, so having two rackets is not an unnecessary luxury.
After wood, rackets were often made of steel, then, aluminum, and then carbon fiber composites.
Modern rackets are made of carbon fiber or fiberglass and metals such as titanium alloys or ceramics.
Because you cannot play tennis without a racket, you must have a racket that you can hold relatively easily.
Not everyone has the same size hands, so there are different grip sizes for tennis rackets.

If you hold the racket with an eastern forehand grip, you should be able to put your index finger in between the palm and ring finger of the hand that is holding the racket.
Beginners usually have a light racket, while professionals opt for a heavier racket. A heavy racket means more power but less maneuverability.
Therefore, starting with a heavy racket is not smart, but it can be beneficial if you are better at the game.
The average weight of a tennis racket is 10.6 ounces, which is 300 grams.
16/19 means there are 16 main strings and 19 cross strings.
An open string pattern (16/18) is ideal for spin and power, whereas a closed string pattern (18/20) is ideal for control.
Hawk-eye technology helps make the match fair. If a player calls for a challenge, a digital system checks if the ball was in or out.
Players can call a challenge when they disagree with an umpire’s call. They are allowed three unsuccessful challenges per set. Challenges cannot be carried into the new set.
A long time ago, women used to play tennis in a full-length dress or skirt that reached the ground.

The main difference is that in wheelchair tennis, the ball is allowed to bounce twice, but only the first bounce has to be in between the lines.
When you experience pain at the outside of your elbow, you likely have a tennis elbow or lateral epicondylitis.
It is caused by overuse of the forearm muscles, which are close to the elbow joint.
These muscles get used in tennis a lot, hence the name tennis elbow, but it can also happen to people who do not play tennis.
The line at the end, where the players serve, is called the baseline. The line on the edge of the box where a serve has to land is called the service line. The lines at the side of the court are called sidelines.
