How long is a tennis match? Typical lengths and the longest ever

Updated on 6 min readBy Marius, founder of 77 Tennis

A professional tennis match lasts about two hours on average. The Professional Tennis Players Association's 2024 player health report put the average at about 120 minutes a match in 2024, and 143 minutes at the four majors, where men play best of five sets. The spread around that average is wide: a lopsided match can be over quickly, while the longest match on record, at Wimbledon in 2010, lasted 11 hours and 5 minutes over three days.

This page is about time. The format that decides how many sets are played is in how many sets are in a tennis match, and how points and games are counted is in how tennis scoring works.

How long a match takes on average

The PTPA report gives average match lengths for three years. It doesn't say on that page which tours or rounds the figures cover, so treat them as a broad guide:

Average minutes per match199920232024
All matches98119120
All four majors139166143

Two things stand out. Matches have got longer: the average rose from about 98 minutes in 1999 to about 120 in 2024. And matches at the majors run longer than the rest; that's also where men's singles are best of five.

What makes a match longer or shorter

Three things decide most of it: the format, how close the players are, and how long they take between points. The first two show up clearly in the point-by-point model behind the win-chance calculator. These are averages from simulating many matches with that model, assuming tiebreak sets:

MatchPointsGamesSets
Best of three, equal players (both hold 81%)16425.62.5
Best of three, mismatch (86% vs 72%)15123.62.4
Best of five, equal players27142.34.1
Best of five, mismatch24037.63.8

Best of five adds about two thirds more points to a match. A close match lasts longer than a mismatch, mainly because it more often goes the distance. Those averages hide a wide range: in the model, one best-of-three match in ten between equal players runs past 220 points.

The time rules

Rule 29 of the ITF Rules of Tennis says play should be continuous and sets these limits, which the tours and tournaments build on:

  • Between points: up to 25 seconds.
  • Changing ends: up to 90 seconds after a game, but no rest after the first game of each set or during a tiebreak.
  • Between sets: a set break of up to 120 seconds.
  • Medical time-out: one of three minutes for a treatable medical condition.
  • Rest period: up to ten minutes, if the event announces it in advance, after the third set of a best-of-five match or the second set of a best-of-three.
  • Warm-up: up to five minutes, unless the event decides otherwise.

The rule is precise about the clock: the time starts when one point finishes and runs until the first serve of the next point is struck. Event organisers can also apply to the ITF to extend the 90 seconds at a change of ends and the 120 seconds between sets, so the breaks aren't identical everywhere.

Put the 25-second limit together with the model's 164 points and the time allowed between points alone comes to about 68 minutes in an average best-of-three match. Add up to 90 seconds at most changeovers and two-minute set breaks, and the allowances add up to well over an hour, before counting the rallies themselves. That's why a two-hour average isn't surprising.

Rain, bad light and curfews are a different matter: they stop the clock altogether, sometimes until the next day. Rain delays, retirements and injuries covers what happens to a position when that happens.

The longest tennis match ever

John Isner beat Nicolas Mahut in the first round of Wimbledon in 2010 in 11 hours and 5 minutes, played over three days, with a final set of 70-68. Guinness World Records lists it as the longest professional tennis match.

A final set like that can't happen at a major any more. The 2026 Grand Slam rulebook says the final set is decided by a 10-point tiebreak, which in the ITF's description starts at six games all. So a final set at the majors now ends 7-6 at the longest, however close it is. Tennis tiebreak rules explains how that tiebreak works.

Why match length matters if you trade

A longer match means more games, and more games mean more breaks of serve, which are what move the price most. With both players holding 81% of the time, about one game in five is a break, so the model's average best-of-three match between equal players has about five breaks, and a best-of-five about eight.

Worked example: what five breaks do to a position

You buy 100 shares of Player A at 51¢ for $51.00 at 3-3 in the first set, with A about to serve. If A holds, the price goes to about 55¢ and the shares are worth $55.00. If A is broken, it drops to about 33¢ and they're worth $33.00, so one game decides a $22.00 swing in what you hold.

Now repeat that about five times over a two-hour match, some breaks in your favour and some against, with the swings getting bigger in later sets. If you plan to hold to the end, plan for that ride. If you'd rather not, decide in advance where you'd sell, as in take-profit and stop-loss for tennis trading.

The time of day matters too: a match that starts late can run past midnight, and some parts of a match are busier on the market than others. When is the best time to trade a tennis match? looks at that.

FAQ

How long is a tennis match on average?

About two hours. The PTPA's 2024 player health report gives an average of about 120 minutes per match in 2024, and 143 minutes at the four majors.

How long is a Grand Slam match?

Longer than a normal tour match, because men's singles at the majors are best of five. The PTPA report puts the 2024 average at the majors at 143 minutes.

What is the longest tennis match ever?

John Isner against Nicolas Mahut at Wimbledon in 2010: 11 hours and 5 minutes over three days, with a final set of 70-68.

How much time is allowed between points?

Up to 25 seconds under the ITF Rules of Tennis, with up to 90 seconds at a change of ends and up to 120 seconds between sets.

Can a match still go on for days?

Not because of the score at a major: the final set there ends in a 10-point tiebreak at six all. Rain, bad light or a curfew can still split a match over two days.
