The length of a football ground can vary depending on the type of football being played. In general, the length of a football ground for professional matches is usually between 100 and 110 meters or 328 to 360 feet. This measurement is taken from the goal line to the opposite goal line.
However, it is important to note that the length of a football ground can also vary in different leagues and competitions around the world. For example, FIFA, the international governing body for football, has defined the size of a football ground for official matches to be between 100 and 110 meters in length.
