Law 1 - The Field of Play
The Penalty Area
 
  • A penalty area is defined at each end of the field as follows:
    Two lines are drawn at right angles to the goal line, 16.5 m (18 yds) from the inside of each goalpost. These lines extend into the field of play for a distance of 16.5 m (18 yds) and are joined by a line drawn parallel with the goal line. The area bounded by these lines and the goal line is the penalty area.

  • Within each penalty area, a penalty mark is made 11 m (12 yds) from the midpoint between the goalposts and equidistant to them. An arc of a circle with a radius of 9.15 m (10 yds) from each penalty mark is drawn outside the penalty area.

Flagposts
 
  • A flagpost, not less than 1.5 m (5 ft) high, with a non-pointed top and a flag is placed at each corner.

  • Flagposts may also be placed at each end of the halfway line, not less than 1 m (1 yd) outside the touch line.

The Corner Arc
 
  • A quarter circle with a radius of 1 m (1 yd) from each corner flagpost is drawn inside the field of play.
