How Long Do Tennis Matches Last? Best-of-3 vs Best-of-5 Explained

A best-of-three-sets tennis match typically lasts around 90 minutes, with most between one and two and a half hours. A best-of-five-sets match — the format used for men's singles at the four Grand Slams — usually runs two and a half to three and a half hours, and a hard-fought five-setter can push well past four. A one-sided best-of-three can finish in under an hour, while marathon five-setters have stretched far beyond that.

A sensible budget is about two hours for a best-of-three match and about three and a half hours for a best-of-five, plus a buffer on either side. Tennis has no fixed running time, so the buffer matters more than in almost any other sport. The sections below explain where the variation comes from.

Almost all professional tennis is played best-of-three sets: the first player to win two sets wins the match. That covers women's singles everywhere, including the Grand Slams, plus men's singles at regular tour events and nearly all doubles. The big exception is men's singles at the four majors — the Australian Open, the French Open, Wimbledon, and the US Open — which is played best-of-five, meaning a player must win three sets. That rule is why Grand Slam night sessions can run into the early morning.

The format changes the math. A best-of-three match contains two or three sets; a best-of-five anywhere from three to five. A competitive set of singles commonly takes 40 minutes to an hour, so each additional set adds a meaningful chunk to the worst case. Tour-level doubles trims from the other direction: it typically uses no-ad scoring and replaces the third set with a 10-point match tiebreak, so doubles matches often wrap up in an hour to 90 minutes.

When a set reaches six games all, it is normally decided by a tiebreak: first to seven points, winning by two. A tiebreak adds around ten minutes to a set, and a match with multiple tiebreaks will run longer than the scoreline alone suggests — a 7-6, 7-6 match can take longer than a routine 6-3, 6-2, 6-2 result in a best-of-five.

The deciding set has its own rule. Since 2022, all four Grand Slams use the same format: at six games all in the final set, players contest a 10-point tiebreak — first to ten, winning by two. This was introduced to cap match length. Before the rule was standardized, some majors required the final set to be won by two clear games, which produced some of the longest matches in the sport's history, including a Wimbledon first-round match in 2010 that lasted more than eleven hours spread across three days. Under current rules, that kind of open-ended marathon can no longer happen at a slam.

Surface is the biggest environmental factor. Clay courts slow the ball down and give it a higher bounce, which lengthens rallies and makes service breaks more common — so clay-court matches, and especially best-of-five matches at the French Open, tend to be the longest of the season. Grass does the opposite: the ball skids through low and fast, serves are harder to return, and points end quickly, which is why Wimbledon sets often move at a brisker pace. Hard courts, used at the Australian Open and US Open, sit in between, with length varying by court speed and conditions.

Level and round matter too. Early-round matches between players ranked far apart frequently end in quick straight sets, while quarterfinals onward tend to pair evenly matched opponents, which means more games per set, more tiebreaks, and longer matches. Weather adds another variable at outdoor events: extreme heat slows play with extra breaks, and rain can suspend a match entirely on courts without a roof.

Tennis is scored in points, games, and sets rather than time. A match ends when one side wins the required number of sets — however long that takes — so there is no equivalent of a final whistle or fourth quarter. The only clocks govern the gaps between play: a serve clock of 25 seconds between points at the majors and on the main tours, 90-second changeovers after odd games, two-minute breaks between sets, and a short warm-up before the first point.

This structure is why tennis scheduling is approximate. A tournament can estimate how long a match will take, but it cannot guarantee it, and medical timeouts, long deuce games, and weather delays all stretch the day further. Broadcasters and fans work from estimates, not fixed end times.

Because match lengths are unpredictable, tournaments schedule several matches on each court in sequence, and only the first match of a session gets a fixed start time. Every match after it is listed as 'followed by,' meaning it begins shortly after the previous match ends. A 'not before' time is a hybrid: the match will not start earlier than the stated time, but it can start much later if the earlier matches run long. Treat 'not before 7:00 pm' as the earliest possible moment, not a promise.

The practical approach is to work backward through the order of play. Check how many matches are scheduled on the court before the one you care about, budget roughly two hours for each best-of-three and three-plus hours for each best-of-five, and start checking live scores as the preceding match reaches its final set. If you are watching from another time zone, convert the session start carefully — a countdown tool like matchcountdown.com shows the scheduled start in your local time so you are not doing daylight-saving math at midnight. Finally, give yourself slack on the back end: the match you tune in for can itself run long.
