🎾 Tennis

What is Tennis?

Tennis is a racket sport played between either two players (singles) or two teams of two (doubles) on a rectangular court divided by a net. Players use a racket to strike a felt-covered rubber ball over the net into the opponent's court, aiming to make it unreturnable. Points are scored in a unique sequence: points → games → sets → match.

History of Tennis

Origins

Tennis evolved from the 12th-century French game of jeu de paume ("game of the palm"), where players hit a ball with their bare hands. The word "tennis" derives from the French "tenez!" ("take!" or "receive!"), called out by the server. The game eventually moved indoors and adopted rackets.

The Birth of Modern Tennis

Major Walter Clopton Wingfield created the modern outdoor version in 1873, initially called "Sphairistikè" (Greek for "skill in playing at ball"). The All England Croquet Club (later the All England Lawn Tennis and Croquet Club) hosted the first Wimbledon Championships in 1877.

Key Milestones

Tennis in the Modern Era

The Open Era (since 1968) transformed tennis into a global professional sport. The "Big Three" — Roger Federer, Rafael Nadal, and Novak Djokovic — have dominated men's tennis for two decades, collectively winning 66 Grand Slam titles. On the women's side, legends like Serena Williams, Steffi Graf, and Martina Navratilova have defined excellence.

Women's Tennis

Women's tennis has been at the forefront of gender equality in sports. The WTA was founded in 1973 by Billie Jean King, who famously won the "Battle of the Sexes" against Bobby Riggs that same year. Women now receive equal prize money at all four Grand Slams.

How to Play Tennis

The Objective

Win points by hitting the ball into the opponent's court in a way they cannot return it. The ball must land within the court boundaries and can bounce once before the opponent must return it (or be hit on the volley before it bounces).

Scoring System

Tennis uses a unique scoring sequence:

Points in a Game:

Games → Sets → Match:

Tiebreak: At 6-6 in a set, a tiebreak is played. Players serve alternately, and the first to 7 points (leading by 2) wins the tiebreak and the set 7-6.

Serving Rules

1. Server stands behind the baseline
2. First serve must land in the service box diagonally opposite
3. Two serves allowed per point (first serve + second serve)
4. A fault (serve misses the box, hits the net, or lands out) results in a second serve
5. A double fault (both serves are faults) loses the point
6. A let (serve clips the net but lands in the correct box) is replayed
7. Server alternates sides each point (left/right)

Basic Techniques & Skills

1. Forehand — The most common stroke; dominant hand swings across the body
2. Backhand — One-handed or two-handed; played on the non-dominant side
3. Serve — Overhead stroke to start each point; flat, slice, or kick serve
4. Volley — Hitting the ball before it bounces (at the net)
5. Overhead smash — Powerful overhead shot on a high ball
6. Drop shot — Delicate shot that barely clears the net and drops near the opponent
7. Lob — High arcing shot that goes over the opponent at the net
8. Slice — Underspin shot that keeps the ball low and skidding

Common Fouls and Violations

Training and Fitness

Physical Requirements

Common Injuries

• Tennis elbow (lateral epicondylitis) — Overuse of forearm muscles
• Rotator cuff strain — From serving
• Ankle sprain — From lateral movement
• Knee injuries — From frequent stopping and changing direction
• Wrist strain — From repetitive gripping

Training Tips for Beginners

1. Start with group lessons — professional instruction prevents bad habits
2. Focus on consistency over power — keeping the ball in play wins more points than hitting hard
3. Practice serving daily — the serve is the most important shot; it's the only one you fully control
4. Watch the ball — keep your eyes on the ball from your opponent's racket to yours
5. Move your feet — good footwork is the foundation of all great tennis
6. Play regularly — 2–3 times per week builds muscle memory and conditioning

Variations of Tennis

Wheelchair Tennis

Played by athletes with physical disabilities. The key rule difference: the ball may bounce twice before it must be returned, with the second bounce allowed outside the court. Governed by the ITF.

Beach Tennis

Played on sand in a court similar to beach volleyball. The ball cannot bounce — every shot is a volley. Uses standard tennis rackets and depressurized tennis balls. Growing rapidly in coastal regions.

Padel Tennis

Played in an enclosed court with glass and metal walls that are in play. Uses solid, stringless rackets and a slightly depressurized tennis ball. Extremely popular in Spain, Italy, and Latin America. One of the fastest-growing sports globally.

Platform Tennis

Played on a raised platform with wire-mesh screens as walls. Primarily in North America. The ball can be played off the screens. Played outdoors year-round, even in snow.

Tenis Para Dos

A casual doubles-focused variant popular in Latin America, emphasizing social play.

FAQ

How do you score in tennis?

Tennis scoring goes: Love (0), 15, 30, 40, Game. If the score reaches 40-40 ("deuce"), a player must win two consecutive points (advantage, then game). Games form sets (first to 6 games, win by 2), and sets form matches (usually best of 3 or best of 5).

How long does a tennis match last?

The average professional tennis match lasts 1.5–3 hours. However, Grand Slam men's singles matches (best of 5) can last 4–5+ hours. The longest match in history was the 2010 Wimbledon first-round match between John Isner and Nicolas Mahut, lasting 11 hours and 5 minutes over 3 days.

What are the Grand Slams?

The four Grand Slam tournaments are the most prestigious events in tennis: Wimbledon (grass, London), French Open (clay, Paris), US Open (hard, New York), and Australian Open (hard, Melbourne). Winning all four in a calendar year is a Calendar Grand Slam, achieved only 5 times in history.

What size is a tennis court?

A regulation tennis court is 78 feet (23.77m) long and 27 feet (8.23m) wide for singles, or 36 feet (10.97m) wide for doubles. The net is 3 feet (0.914m) high at the center and 3.5 feet (1.07m) high at the posts.

How much does a tennis racket cost?

Tennis rackets range from $30–$300+. Beginners can find quality rackets for $30–80. Intermediate players typically spend $80–200, while advanced players may invest $150–300+ for high-performance rackets.

What is a let in tennis?

A let occurs when a serve clips the top of the net but lands in the correct service box. The serve is replayed without penalty. Lets can also be called if a point is disrupted by an external factor (ball rolling onto court, etc.).

Why is "zero" called "love" in tennis?

The term "love" likely derives from the French word "l'œuf" (egg), because a zero looks like an egg. Another theory is that it comes from the Dutch word "lof" (honor), meaning playing for honor rather than money when at zero.

Can anyone learn to play tennis?

Yes. Tennis is suitable for all ages and fitness levels. Many clubs offer beginner programs, Cardio Tennis (group fitness), and wheelchair/adaptive programs. All you need to start is a racket, balls, and access to a court.
