A tennis net is a crucial component of a tennis court, dividing the playing area into two equal halves. It is typically made of durable materials like nylon or polyester, designed to withstand the impact of tennis balls. The net is 3 feet high at the center and 3.5 feet at the posts, ensuring a consistent playing experience. The net is anchored to the ground with posts on either side, which are usually made of metal or wood. Proper tension is essential for the net to function effectively, as it affects the trajectory of the ball during play.
