A net (42 feet long, 3 feet 6 inches high at the posts, 3 feet high in the middle) is stretched across the full width of the court, parallel with the baselines and divides the tennis court into two symmetrical sides. The net should be made properly and touch the ground surface, so that the ball cannot get through during a game. In order to put the net in the middle of the court you will need net posts (3,5 feet tall and 6 inches wide), a metal cable, a white strap (2 inches wide), which controls the height and is fastened to the ground and a white band (2-2.5 inches in depth).
