Laws of the Game

IFAB currently acknowledges 17 laws of soccer that are the standard for any professional or international match played. They are as follows:

Law 1: The Field of Play

Soccer can be played on either grass or artificial turf, but the surface must be green in color. The field must be rectangular in shape, and distinctly marked by two short goal lines and two long-touch lines. The field is divided into halves, separated by the halfway line, which runs from the midpoints of each touchline. At the midpoint of the halfway line is a marked center point surrounded by a lined center circle with a radius of 10 yards. Opposing players are not allowed to enter this circle during the possessing team’s kick-off. The length of the touch line must be greater than the length of the goal line.

Regulation lengths are:

• Touch line: Minimum 90 meters (100 yards), maximum 120 meters (130 yards)
• Width (goal line): Minimum 45 m (50 yds), maximum 90 m (100 yds).
• At each end of the field is an eight-yard-wide goal centered along the goal line.
• Six yards from each goal post along the goal line and six yards out into the field (perpendicular to the goal line) is the goal box.
• Extending 18 yards from each goal post along the goal line and 18 yards out into the field (perpendicular to the goal line) is the penalty box.
• In each of the four corners of the field is a five-foot-high corner flag.
