THE FIELD OF PLAY – LAW 1
Like most sports, the rules of soccer start with a detailed explanation of the lines and equipment of the field of play. For soccer, these include the field surface, perimeter markings (boundary lines), field dimensions, goals, interior markings, and corner flags. For the full-sized outdoor game, these are all captured in the Laws of the Game, “Law 1 – The Field of Play.”
The field may be natural grass or artificial turf. In addition, a “hybrid system” field, utilizing an integrated combination of artificial and natural materials may be used if permitted by competition rules. If artificial turf is used, it must be green in color. The lines that are used to mark the field must all be straight and no wider than five inches. All lines must be the same width, based on the thickness of the goalposts.
The field is a proper rectangle with accurate 90-degree corners. The perimeter lines, or the lines that bound the field, also known as the boundary lines, are defined as the “Goal Lines,” at each end of the field, and the “Touch Lines,” along the sides. The Goal Lines, the two shorter lines of the rectangle, are commonly referred to as the “end lines” and the Touch Lines, the two longer lines of the field, are commonly referred to as the “sidelines.”
The field dimensions or the overall size of the field, based on the distances of the boundary lines, are not identical for all fields. The length and width of the field are set to minimum and maximum allowances. This lack of standardization is based on the historical unavailability years ago of large, flat, places to play. The minimum length of the Goal Lines is 50 yards and the maximum length of the Goal Lines is 100 yards. The minimum length of the Touch Lines is 100 yards and the maximum length of the Touch Lines is 130 yards. To establish and maintain a rectangular field, the two Goal Lines must always be shorter than the two Touch Lines. The Goal Lines must both be of equal length and the Touch Lines must both be of equal length.
Two Goals are placed, one each, in the center of the goal lines. The goals must be identical in size, shape and construction. According to Law 1:
“A goal consists of two vertical posts equidistant from the corner flagposts and joined at the top by a horizontal crossbar. The goalposts and crossbar must be made of approved material. They must be square, rectangular, round or elliptical in shape and must not be dangerous. The distance between the inside of the posts is …8 yards and the distance from the lower edge of the crossbar to the ground is … 8 feet.”
“The goalposts and the crossbar must be white and have the same width and depth, which must not exceed …5 inches. Nets may be attached to the goals and the ground behind the goal; they must be properly supported and must not interfere with the goalkeeper.”
The interior markings consist of the halfway line, center mark, center circle, goal areas, penalty areas, penalty marks, penalty arcs, and corner arcs.
The Halfway Line divides the field into two equal halves, joining the midpoints of the two sidelines, parallel to the end lines. The Center Mark is a small, fully-enclosed, circle drawn at the midpoint of the halfway line. Using the exact center of the center mark, a radius of 10 yards is used to mark the Center Circle around it.
The Goal Areas are 6-yard x 20-yard rectangles closest to the goals. Six yards from the inside of each goalpost, in the direction of each corner, a line is drawn six yards into the field of play perpendicular to the end line. The end-points of these lines are connected with a line parallel to the end line.
The Penalty Areas are 18-yard x 44-yard rectangles farther away from the goals. Eighteen yards from the inside of each goalpost, in the direction of each corner, a line is drawn eighteen yards into the field of play perpendicular to the end line. The end-points of these lines are connected with a line parallel to the end line.
A Penalty Mark, usually consisting of a small, fully-enclosed, circle is drawn within both penalty areas at a point 12-yards into the field from the midpoint between the goalposts and equidistant from each post when measured from the exact center of the mark.
Marked outside of the penalty area, the Penalty Arc is that portion of a circle with a radius of 10 yards from the exact center of the penalty mark.
The Corner Arcs are quarter circles drawn inside the field of play with a radius of 1-yard from each of the corners. Corner Flags, or flagposts, are to be placed at each corner. Optionally, a flagpost may also be placed at least 1-yard away from the intersection of the halfway line with the sideline. The posts themselves must all be at least 5-feet tall, with rounded tops, and have a flag attached at the top.
As an option, eight marks (“optional marks” or “hash marks”) may be added, just outside of the field of play and perpendicular to the perimeter lines, one each at the sideline and the end line, 10-yards from each corner. This is for the benefit of the referees to ensure the proper distance is maintained by defenders when a corner kick is taken.
