Soccer nets are large, rectangular structures placed at each end of a soccer field. They are designed to catch the ball when a goal is scored. Typically made of durable materials like nylon or polyester, soccer nets are attached to goalposts and a crossbar, forming a goal area that measures 8 feet high and 24 feet wide. The primary purpose of soccer nets is to provide a clear visual indication of when a goal has been scored. They come in various sizes and styles, depending on the level of play, from youth leagues to professional competitions like the FIFA World Cup.
