US Open 2026: Scoring

Scoring
Love. Deuce. 40–40, ad in, a tiebreak at six games all. Tennis scoring sounds like it was invented by a medieval accountant with a flair for drama — and it more or less was. Here’s the whole system, drawn where it happens: on the court — plus the part the US Open invented itself.
The map
One court, fully labeled
Before the rules, the territory. Every rule on this page happens somewhere on this rectangle — learn it once here, and the close-ups below will always tell you where you are.
This is the whole map. Singles lives between the inner sidelines (27 ft); doubles annexes the two 4½-ft alleys (36 ft). Everything on this page happens somewhere on this rectangle — hover any label to find it. Proportions are the real ITF dimensions.
Points
Scoring a game: love, 15, 30, 40
The famous part. A game is a race to four points, win by two — counted in the least helpful units in sports. The ladder explains it; the court below plays it out.
Nobody knows for certain why tennis counts this way — the best story traces 15/30/45 to the quarters of a clock face, with 45 lazily shortened to 40 somewhere in the fifteenth century. The rule that matters: four points, win by two. At 40-all (“deuce”) you need two in a row: win one and you have the advantage; win the next and it’s game — lose it and you’re back at deuce.
The example game
From love to game, in ten points
“What a hold. The server painted the service line for an ace, snuck in for as pretty a volley-and-drop as you’ll see all fortnight, and slammed the door with a forehand into the open court — but my goodness, the returner made him earn it: two clean passing winners and a double trip to deuce off some cheap errors. Ten points, five different ways to end one, and every line of the stat sheet got a workout.”
Now watch it yourself: ten scripted points, one click at a time. The scoreboard, the stat sheet, and the recaps teach the vocabulary as you go.
One click, one point: watch it play out on the court, then read what just happened before you take the next one — ten points, through a double deuce, to game. The serve always starts from the left end, and the stat sheet fills in as you go.
| Game stats | Srv | Ret |
|---|---|---|
| Aces | 0 | 0 |
| Winners | 0 | 0 |
| Unforced errors | 0 | 0 |
| Forced errors | 0 | 0 |
| Net points won | 0 | 0 |
Ten scripted points — with JS off (or reduced motion), the ladder above tells the same story statically.
The serve
Two tries, one diagonal
Every point starts the same way: a serve, struck from behind the baseline, landing in the little box diagonally across the net. Everything that can happen to it is drawn here.
Every serve is played diagonally, from behind the baseline into the service box across the net — deuce court to deuce court, then ad to ad, alternating every point (both serves of a point come from the same side). You get two tries; the returner just has to be ready. And the let is the rulebook’s one mulligan: tape-and-in replays the serve, as many times as physics cares to allow.
The pyramid
Games make sets make the match
Tennis is a tournament of nested races: points win games, games win sets, sets win the match. Pull back and the whole structure fits in one picture.
Format as of 2026-07-13 — re-verified before each tournament (the sport periodically debates best-of-three for the men; nothing has changed for 2026).
Six games all
The tiebreak
When a set jams at 6–6, tennis stops playing games and runs a sprint. The scoring is simple; who serves from where is famously not — so step through it.
Thirteen points of rotation — enough to see the whole pattern repeat. The strip above shows it all at once.
Made in New York
The US Open’s tiebreak firsts
The tiebreak you just learned isn’t a neutral fact of tennis — it’s a US Open invention that took the other majors half a century to fully adopt.
Simultaneous set point — sometimes match point — for both players at once, a thing tennis had never allowed in ninety years. The tournament flew red flags on courts where a sudden-death tiebreak was under way so the grounds knew where the drama was.
Before 1970, a tennis set could simply refuse to end — 6–6 became 10–10 became 22–20 while the rest of the schedule quietly died. Jimmy Van Alen — Newport blueblood, founder of the Tennis Hall of Fame, and the sport’s most persistent scoring heretic — had spent years hawking his fix: a sprint to settle any set stuck at 6–6. In 1970 the US Open, then played at Forest Hills, made it real — the first Grand Slam to use a tiebreak, in his nine-point sudden-death form. The New York Times called it the most revolutionary change in the sport’s scoring since the game took shape.
The purists eventually won a partial repeal: from 1975 the US Open swapped sudden death for the calmer 12-point tiebreak — first to seven, win by two — the version every set on this page uses today. But the tournament kept its nerve where it counted: it went on settling deciding sets with a tiebreak at 6–6, alone among the four majors, for five decades — while Wimbledon and the others let final sets run to 70–68 if they had to.
The sport caught up in March 2022, when all four Grand Slams standardized a 10-point tiebreak at 6–6 in the final set. Every deciding set at every major now ends the way the US Open always insisted it should: with a sprint. The grounds moved from Forest Hills to Flushing Meadows in 1978; the idea stayed.
Speak tennis
The glossary, on the court
The words that make the broadcast make sense — each one pointed at the place it happens.
Everything in one picture — if a term is about a place (ad court, the alley, break point pressure on a second serve), it lives somewhere on this rectangle. The big labeled court up top has the dimensions.
Compiled from the ITF Rules of Tennis (court dimensions, scoring, service, tiebreak mechanics), usopen.org (the tournament’s match format), the Grand Slam Board’s 2022 final-set tiebreak announcement, and tennis-history sources including the International Tennis Hall of Fame for the Van Alen story. Scoring and dimensions are stable facts; the one drifting line — the US Open’s match format (women best-of-3, men best-of-5, 10-point final-set tiebreak) — was verified on 2026-07-13 and is re-checked before each tournament.
