The USTA has passed rules governing competition for 10-and-under tennis tournaments. The rules require that 10-and-under tournaments be played using slower-moving and lower-bouncing balls, on smaller courts and utilizing shorter, lighter racquets. The rule change follows the International Tennis Federation's rule change and took effect on January 1, 2012. It will apply to all USTA-sanctioned events for children 10-and-under.
The specifications for the revised system hold that all tournaments for those ages 9-10 be played on 60-foot courts using orange low-compression tennis balls and regulation nets or, for those more experienced and more skilled players, on 78-foot courts with green lower-compression balls. Tournaments for those 8-and-under are to be played on 36-foot courts using red foam balls and nets at a height of 2 feet, 9 inches.
