Law 1 The Field of Play - Field Markings.
The field of play must be rectangular and marked with lines. These lines belong to the areas of which they are boundaries.
The two longer boundary lines are called touch lines.
The two shorter lines are called goal lines.
The field of play is divided into two halves by a halfway line, which joins the midpoints of the two touch lines.
The centre mark is indicated at the midpoint of the halfway line. A circle with a radius of 9.15 m (10 yds) is marked around it.
Marks may be made off the field of play, 9.15 m (10 yds) from the corner arc and at right angles to the goal lines and the touch lines, to ensure that defending players retreat this distance when a corner kick is being taken.
