A net is stretched across the full width of the court, parallel with the baselines, dividing it into two equal ends. It is held up by either a cord or metal cable of diameter no greater than 0.8 cm. The net is 3 feet 6 inches high at the posts and 3 feet high in the centre. The net posts are 3 feet outside the doubles court on each side or, for a singles net, 3 feet outside the singles court on each side.
