Hard courts are a type of tennis playing surface made from a combination of asphalt or concrete, often coated with acrylic materials. These surfaces provide a consistent bounce and are known for their durability, making them popular for both recreational and professional play. Major tournaments, including the US Open and Australian Open, are held on hard courts. Players often find hard courts to be faster than clay courts but slower than grass courts. The surface can be tough on players' joints, so proper footwear and conditioning are essential. Hard courts are widely used in many countries, contributing to their popularity in the sport.
