After Orange, the next level is Green. The Green ball is very similar to the traditional yellow tennis ball but with a slightly lower compression so it rebounds lower off the court after a bounce.
The Green court is the same dimension as the traditional Yellow court: 78 feet by 27 feet for singles and 78 feet by 36 feet for doubles. The net is 3 feet at the center and 3-foot-6 at the net posts.
Ages: 10 -14 years
