The US Open is one of the most prestigious and iconic tennis tournaments in the world. As one of the four Grand Slam events, along with the Australian Open, French Open, and Wimbledon, the US Open attracts the top tennis players from around the globe each year. Millions of tennis fans tune in to watch the high-stakes competition unfold in New York over the two week tournament. But one question lingers in the minds of casual and die-hard tennis fans alike – just how many sets are played in the US Open? Understanding the set format is key to appreciating the grueling physical and mental demands players must withstand to emerge victorious in this pinnacle event.


The US Open is the final Grand Slam tennis tournament of the year, held annually in late August and early September at the USTA Billie Jean King National Tennis Center in Flushing Meadows, New York. As one of the most important tournaments in tennis, the US Open features the top professional tennis players in the world competing for the coveted US Open Championship title and a share of substantial prize money.

A set in tennis refers to a segment of a match that is completed when one player wins 6 games, provided they have a margin of at least 2 games over their opponent. For example, if the score reaches 6-4, the set is over. If the score reaches 6-5, the set continues until one player attains a 2 game lead. The first player to win the designated number of sets wins the match.

Knowing the number of sets played in the US Open matches is useful for both players and spectators. The set format determines the length of matches and the physical demands on players. It also impacts viewing experience for fans, as more sets means more tennis action. Given that the US Open utilizes different set formats across varying events, it is valuable for both hardcore and casual tennis fans to understand these distinctions.

How Many Sets Are Played in the US Open?

The set formats vary between events at the US Open. Here is a breakdown of how many sets are played across each event:

  • Women’s Singles & Doubles Matches: Best-of-three sets
  • Men’s Doubles Matches: Best-of-three sets
  • Men’s Singles Matches: Best of five sets

For both the women’s singles and doubles matches, as well as the men’s doubles matches, the victor needs to win 2 out of 3 sets to win the match. This is referred to as the best-of-three sets format.

However, for the men’s singles matches, the best-of-five sets format is used. This means that the winner must claim 3 sets out of the 5 in order to win the match. The extended format for men’s singles leads to longer match times and increased physical exertion on the players.

This differentiation between the best-of-three set matches and best-of-five set matches is unique to the US Open when compared to the other Grand Slam events.

Why Are There Different Numbers of Sets Played in Different Grand Slams?

While the US Open utilizes different set formats for men’s singles compared to the other events, the remaining Grand Slam tournaments actually use a consistent best-of-five set format for both men’s and women’s singles matches.

The use of the best-of-five set format exclusively for men’s singles matches is a tradition that was started by the US Open tournament in 1970. At that time, the US Open decided to adopt the best-of-five set format for men’s singles to increase excitement and match length. The other Grand Slam tournaments eventually followed suit by adopting the best-of-five set format for men’s singles in the following years:

  • Australian Open: Adopted best-of-five sets in 1973
  • French Open: Adopted best-of-five sets in 1974
  • Wimbledon: Adopted best-of-five sets in 2018

There are a few leading theories as to why the US Open has retained the best-of-three set format for women’s singles while the other Slams transitioned to best-of-five:

Tradition and uniqueness: The best-of-three set format for women’s singles matches has been a long-standing tradition at the US Open since the beginning of professional tennis. Using a different format than the other Slams adds an element of uniqueness.

Physical demand: The best-of-five set format places substantial physical strain on players. The argument has been made that men are better equipped to handle the extended play. Retaining the best-of-three format for women’s singles matches aims to protect players from overexertion.

Equality: Some suggest that maintaining just best-of-three sets for both men’s and women’s singles promotes gender equality by having an equal format.

Television: Shorter women’s matches with fewer sets may be better suited for TV time constraints. Broadcasters have limited time slots, so shorter women’s matches allow more matches to be shown.

There is still debate around whether the US Open should align the women’s singles competition with the other Slams by switching to best-of-five sets. While some argue it is needed to achieve fairness and consistency, others want to preserve the US Open’s tradition and the current women’s format. The number of sets played will likely continue to be a point of discussion.


Understanding the unique set formats used at the US Open provides valuable insight into this renowned Grand Slam tournament. The US Open adopted best-of-five set matches for men’s singles in 1970, distinguishing itself as the only Major to not have equal set formats for men’s and women’s singles matches. While the other Grand Slams transitioned both competitions to best-of-five set formats from 1973 to 2018, the US Open has continued its tradition of retaining best-of-three sets for women’s singles.

The decision stems from a combination of factors including tradition, concerns over physical demands, a desire for uniqueness, television, and ideology surrounding equality. Moving forward, it will be interesting to see if the US Open eventually aligns with the other Majors in adopting best-of-five sets for women’s singles as well. For now, the singular format adds to the tournament’s identity and provides shorter women’s matches that appeal to broadcasters. Understanding the nuances of the US Open set formats enhances any tennis fan’s experience watching and engaging with this marquee Grand Slam event.
