Red Ball Tennis refers to a specific type of tennis designed for younger players, typically between the ages of 4 and 8, who are just starting to learn the game. It uses a red, low-compression tennis ball, which is larger, softer, and slower than standard tennis balls, making it easier for young players to hit and control. The purpose of red ball tennis is to create a more accessible and enjoyable introduction to the sport by adapting both the equipment and the court size to the child’s skill level.
