The standard length of a tennis match, if it goes to five sets, varies significantly, but it typically lasts between 2 to 4 hours. However, there are exceptional matches that can extend much longer, especially in Grand Slam tournaments where players may play to the best of five sets. Factors such as the playing styles of athletes, weather conditions, and match intensity can influence the overall duration. Players must maintain stamina and focus to navigate through an extended match successfully.
