Quick answers
Why is tennis scored 15, 30, 40 — and why is zero called love?
The scoring descends from medieval French real tennis, and the leading theory ties 15-30-45 to the quarters of a clock face, with 45 later shortened to 40 for speed of calling. 'Deuce' comes from the French 'a deux' — two points needed to win. 'Love' for zero most likely derives from 'l'oeuf', the French for egg, describing the shape of a zero (the same logic as cricket's 'duck'), though some etymologists prefer 'playing for love', meaning for nothing. The structure itself is tactical genius: because points build into games and games into sets, not all points are equal — break points and set points concentrate pressure — and no lead is ever mathematically safe, which is why tennis produces so many famous comebacks.
What exactly is a Grand Slam in tennis?
Strictly, the Grand Slam means winning all four major championships — the Australian Open, Roland Garros (French Open), Wimbledon and the US Open — in a single calendar year. Only five singles players have ever done it: Don Budge (1938), Maureen Connolly (1953), Rod Laver (1962 and 1969, the only double), Margaret Court (1970) and Steffi Graf (1988, who added Olympic gold for the only 'Golden Slam'). Colloquially, each of the four tournaments is now called 'a Grand Slam' or 'a major', and winning all four across a career — as Agassi, Serena Williams, Nadal and Djokovic did — is a 'career Grand Slam'. Holding all four at once across two seasons, as Djokovic did in 2015-16 and Serena did twice, is a non-calendar Slam.
Who has won the most Grand Slam singles titles?
Novak Djokovic and Margaret Court share the all-time record with 24 Grand Slam singles titles each. Djokovic reached 24 at the 2023 US Open, and all of his came in Open Era fields; Court won 13 of hers before the Open Era began in 1968, including 11 Australian titles in years when many top internationals skipped the trip — which is why many analysts treat Serena Williams's 23, all won in the professional era between 1999 and 2017, as the benchmark women's figure. Among other men, Rafael Nadal finished with 22 and Roger Federer with 20. Active leaders as of the end of the 2025 season: Carlos Alcaraz with 6 majors and Jannik Sinner with 4, with Iga Swiatek on 6 in the women's game.
What is the difference between the ATP and the WTA?
The ATP (Association of Tennis Professionals) runs the men's professional tour and the WTA (Women's Tennis Association) runs the women's tour; each operates its own tournaments, computer rankings and season-ending Finals. Both are separate from the four Grand Slams, which are owned by their national federations, and from the ITF, the sport's global governing body that oversees the rulebook, the Davis Cup and Billie Jean King Cup, and the Olympic tournament. Billie Jean King founded the WTA in 1973; the men organised the ATP in 1972 and launched their computer rankings the following year. The tours share many combined events, including all four majors and several 1000-level tournaments, but they negotiate their own prize money and media deals — one reason directly comparing men's and women's records is so difficult.
How do clay, grass and hard courts change the game?
Surface changes the physics of the bounce and therefore the tactics. Clay (Roland Garros) is slow and high-bouncing: rallies lengthen, heavy topspin is rewarded, players slide into shots, and big servers lose much of their edge — which is why clay specialists exist. Grass (Wimbledon) is the opposite: the ball skids low and fast, slice stays below the knees, serves dominate, and points are short. Hard courts (Australian and US Opens) sit in between with the truest bounce, favouring all-court players. The differences were once so extreme that between Borg in 1980 and Nadal in 2008 no man won Roland Garros and Wimbledon back to back; modern surface homogenisation has narrowed the gap, but winning that 'Channel Slam' — as Alcaraz has done — remains the sport's best test of adaptability.
What is the longest tennis match ever played?
The longest tennis match ever played is John Isner versus Nicolas Mahut, Wimbledon 2010 first round: 11 hours 5 minutes over three days, Isner winning 6-4, 3-6, 6-7, 7-6, 70-68. That 138-game fifth set alone ran past eight hours; the Court 18 scoreboard froze. It forced the majors later move to a uniform 10-point final-set tiebreak at 6-6 (agreed 2022), so a repeat is now blocked by rule. Searchers asking for the longest US Open match are looking at a different mark: Dan Evans defeated Karen Khachanov in the 2024 first round in 5 hours 35 minutes — the longest US Open since tiebreaks arrived in 1970, passing Edberg-Chang 1992 semi-final (5h26). The longest major final remains the 2012 Australian Open, Djokovic over Nadal in 5h53. Scrub years on this records page to separate absolute, Slam-final, and US Open marks.
Tennis is neither the cheapest nor the most expensive sport to begin. A racket, shoes and a can of balls get you on court; those three together start around $150–250 in the United States or £120–200 in the United Kingdom (2025). Where money really goes is hourly: lessons and court hire account for most ongoing spend, and both vary sharply by city and indoor versus outdoor play. Figures below use 2025 US and UK market rates for beginners.
Club culture matters as much as technique. In the United States and United Kingdom the usual path runs lessons → club membership → USTA or LTA leagues and social play. Doubles-heavy club tennis dominates in some countries where court supply is tight — worth knowing if you travel — but American and British beginners should plan for both singles fundamentals and doubles skills: volleys, poaching and partner movement. Someone who only hits against a wall and drills groundstrokes can still struggle to find games six months in.
Gear and budget
Racket (beginner frame)
Starter price US $80–250 / UK £70–200 (2025)
Buy early but not in a hurry. For the first month or two, try several rental rackets at your club or pro shop before committing. Weight 285–300 g and head size 100–105 sq in is a sensible window. Frames under 260 g feel easy but absorb shock poorly and can invite tennis elbow. Pro-model rackets are usually 315 g or heavier — skip them at first. Prior-year or verified used frames often deliver the same performance for half the price.
Tennis shoes (court-specific)
Starter price US $80–160 / UK £70–140 (2025)
The one item you cannot compromise. Running shoes prioritize forward motion and lack lateral support; tennis's sudden side-to-side stops can roll an ankle in ordinary trainers. Hard-court and clay soles differ; most public US and UK courts are hard or artificial clay, so hard-court or all-court shoes fit most beginners. Replace every 6–9 months if you play two or three times a week — worn soles mean slips.
Strings and restringing
Starter price US $25–45 / UK £22–40 per job (2025)
Factory strings on new rackets are consumables. Beginners should start with nylon or multifilament at 45–50 lb. Polyester gives control but transmits harsh shock to elbows not yet strong enough to absorb it. Before buying a new racket because you lack power, try dropping tension 2–3 lb — far cheaper and often enough.
Tennis balls
Starter price US $3–5 / UK £3–4 per can of 3 (2025)
Coaches supply balls during lessons, so you need not buy immediately. Once you play matches, clubs usually rotate fresh cans among members — budget a can or two per month. Pressurized balls lose bounce within two to three weeks of opening even with the lid on. For solo wall or ball-machine work, pressureless practice balls last longer and save money.
Overgrip
Starter price US $5–10 / UK £4–8 for a 3-pack (2025)
Thin tape wrapped over the handle — cheap but influential. A slick grip makes you squeeze harder unconsciously, which feeds elbow and wrist problems. Replace every two to four weeks at two or three sessions per week. If the handle feels thin, add an extra layer rather than switching rackets.
Racket bag
Starter price US $30–100 / UK £25–85 (2025)
Can wait. A thin cover from a racket purchase is fine until you carry multiple frames, spare clothes and balls. If you leave rackets in a hot car trunk in summer, invest in a bag with insulation — heat kills string tension and melts grip adhesive faster than you expect.
Performance wear and hat
Starter price US $30–80 / UK £25–65 (2025)
Any athletic kit works at first, but outdoor public courts in the US and UK make sun protection worthwhile sooner than beginners expect. Some private clubs prefer collared shirts — check before joining. Thick-toe tennis socks ($8–15 / £6–12 per pair) prevent blisters and toenail damage for minimal outlay.
How to start
Secure a lesson slot first
The first gate in US and UK tennis is availability, not ability. Popular club programs and municipal courts book out; community-center courses often fill by term. Check your local park district, LTA or USTA-affiliated facility, and a nearby indoor club at once and align registration windows. Do not buy a racket yet — use rentals.
Tip Lessons need to be at least twice a week to stick. One 30-minute session weekly means relearning last week's feel each time — same money, half the progress. If budget is tight, shorten the block and stay intensive rather than dropping to once a week.
Forehand, backhand and footwork (1–4 months)
The first months are really about two groundstrokes. Forehand with semi-western grip and open stance; backhand two-handed for most beginners. The goal is not power but sending eight of ten balls over the net into the court — enough to sustain a slow rally.
Tip Most beginner errors start in the feet, not the swing. A split step as the opponent strikes widens reach immediately. Wall hitting is overrated and risky: the ball returns too fast and trains a shortened backswing you will have to unlearn.
Serve, volley and scoring (4–8 months)
Once groundstrokes stabilize, add serve and volley — you need both to play a real game. Learn the scoring chain: 15–30–40, deuce and advantage, win by two games, tiebreak at 6–6. The server calls the score aloud; not knowing it means asking every point in your first matches.
Tip Learn serve with a continental grip from day one. A forehand grip feels easier short term but cannot produce spin for a reliable second serve — and serve is the hardest stroke to rebuild later.
Play doubles (6–12 months)
Club tennis in the US and UK runs heavily on doubles even when singles dominates on television. The court widens to the doubles alleys, partners work front and back, and many points end at the net. Learn basic positioning, the server's partner poaching, and who covers lobs. From here match volume matters as much as stroke quality.
Tip The fastest way to be welcomed in doubles is not hitting winners but avoiding double faults. They cost points your partner cannot touch — keep second serves spinny and in, not fast.
Join a club
Lessons alone rarely supply regular opponents or guaranteed court time. US clubs (often USTA-affiliated) and UK clubs (LTA-registered) block court hours for members and organize social play and box leagues — far easier than winning public-court booking wars alone. Workplace teams, park programs and Meetup-style groups are alternate entry points.
Tip Before paying dues, ask how many games beginners actually get. Skill-stacked clubs leave newcomers fetching balls for two hours. Match the club's regular session times to your schedule — many run weekday mornings or early evenings.
First league or tournament
USTA league tennis and LTA local leagues use rating bands (NTRP in the US; LTA ratings in the UK) so newcomers face similar levels. Formats vary — doubles is common in social leagues; singles dominates many USTA adult divisions. Short sets and no-ad scoring speed up beginner events. Park-district or club round-robins are low-pressure first steps.
Tip Promotion up a level is often permanent once you win — rushing upward before match toughness develops means early-round exits and fewer total games. For the first year or two, prioritize match count over moving up.

Common injuries and prevention
Tennis elbow (lateral epicondylitis)
Common enough to carry the sport's name — and paradoxically more frequent in beginners than pros. Causes include wristy backhands, off-centre contact and poor string setup. Prevention: nylon or multifilament at 45–50 lb, racket weight at least 285 g for vibration absorption, and a two-handed backhand to start. Rest alone rarely fixes it; add eccentric forearm-extensor strengthening.
Shoulder impingement and rotator cuff strain
Repeating overhead serve and smash motions without trunk and leg drive loads the shoulder. Beginners who arm the serve feel it first. Learn serve as a full-body chain from trophy position through knee bend and rotation; band work for external rotation two or three times weekly; cap full-effort serves at 60–80 per session.
Ankle sprain
The most common acute tennis injury — sudden lateral stops on unsupported footwear. Wear court shoes and replace them every 6–9 months at two or three sessions per week. On gritty or damp hard courts, brush the surface before play; single-leg balance drills reduce recurrence.
Achilles tendinopathy and rupture
Especially risky for adults returning in their 30s and 40s. Explosive first steps from standstill load the tendon without warning — ruptures often hit early in the first game. Warm up with jogging, side steps and short sprints for ten minutes rather than static stretching; eccentric calf drops two or three times weekly; increase frequency gradually — do not jump from once to three times a week overnight.
Entry cost for racket, shoes and consumables runs roughly $150–350 / £120–280 (2025). Monthly ongoing spend with lessons and court time typically lands at $100–250 / £80–200 — lower with group lessons and public courts through a club, higher with private coaching and indoor hire in a major city. Avoid buying two rackets in year one and the budget stays manageable.
What separates players who last from those who quit within a year is not talent but access to games. Lessons without a club or league leave nowhere to apply what you learned. Around six months in — even if strokes still feel rough — start doubles and box-league play. You will learn more on court in a month than in another month of drills alone.
