1. The Field of Play - The field of play is the surface on which the game of soccer is played on. This law regulates everything regarding line markings, soccer pitch dimensions and how to use them properly. For example, a soccer pitch must be between 90 and 120 meters long and 45 to 90 meters wide. However, it must also have a rectangular shape, so you can't have a square field with a length and width of 90 at the same time.
Other basic rules of soccer and field measurements are specified in this law, such as the dimensions of each goal (7.32 meters long and 2.44 meters high), the diameter of the centre circle (18.30 meters) or the distance between the penalty spot and the goal (11 meters, perpendicularly on the goal)
