The type of surface used for the majority of tennis tournaments is hard court, specifically a synthetic surface like acrylic or concrete. Hard courts provide a consistent bounce and are preferred for professional play due to their durability and maintenance ease. They strike a balance between the faster pace characteristic of grass courts and the slower pace of clay courts, allowing players to employ diverse strategies. Major tournaments, including the US Open and Australian Open, are played on hard courts, underscoring their importance in the sport.
