14 Unique Rules US Open Players and Spectators Must Follow, Including Dress Codes and Bathroom Breaks

The US Open tennis tournament is a prestigious event that both players and spectators eagerly anticipate every year. As the fourth and final Grand Slam tournament of the year, held in August 2025, it comes with a set of unique rules and regulations that all participants must adhere to, ensuring a smooth and fair competition.

Eric Butorac, the then-director of player relations for the United States Tennis Association and a former doubles pro, highlighted the differences in rules among the major tournaments. He explained that while the rules of the sport remain the same across the Australian Open, French Open, Wimbledon, and US Open, each tournament has its unique set of regulations for players and spectators.

For players, qualifying for the US Open requires a minimum age of 14 years old, with no maximum age limit. Young talents like Coco Gauff have made their mark on the tournament in recent years, proving that age is just a number in the world of tennis. The pathway to entering the championship tournament includes direct entry based on world ranking, qualifiers from the Qualifying Tournament, and wild card entries.

To ensure fair play and sportsmanship, players competing in the US Open must adhere to a specific Player Code of Conduct. This includes guidelines on behavior, language, and attire on and off the court. Any breaches of the code may result in penalties or disqualification from the tournament, emphasizing the importance of upholding the integrity of the game.

Spectators attending the US Open are also expected to follow a Guest Code of Conduct, which outlines proper etiquette and behavior while watching the matches. From dress attire to alcohol consumption and court etiquette, spectators play a vital role in maintaining the tournament’s atmosphere and respect for the players.

Dress code regulations apply not only to players but also to spectators, who are required to dress in a professional and respectful manner. Indecent or offensive clothing and accessories are strictly prohibited, reflecting the tournament’s commitment to upholding high standards of decorum.

In a move towards fairness and equality, the US Open made history in 2023 by having both male and female players use the same tennis balls during matches. This decision, driven by player feedback and discussions, aimed to ensure uniformity and consistency in the equipment used by all competitors.

Additionally, the tournament introduced measures to support the mental health and well-being of players, including access to quiet rooms and mental health resources. Recognizing the pressures of elite competition, these initiatives aimed to provide a supportive environment for athletes to perform at their best.

From the ball crew tryouts to the handling of bathroom breaks and time constraints during matches, the US Open’s rules and regulations are designed to uphold the integrity and fairness of the tournament. As the pinnacle of the tennis calendar, the US Open remains a beacon of excellence and sportsmanship in the world of professional tennis.
