Field Surface
According to FIFA rules, matches can be played on neutral or artificial surfaces. The color of artificial surfaces must be green.
Field Marking
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 fi eld 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.
Dimensions
The length of the touch line must be greater than the length of the goal line.

Length (touch line) : minimum 90 m (100 yds)
maximum 120 m (130 yds)

Width (goal line): minimum 45 m (50 yds)
maximum 90 m (100 yds)

All lines must be of the same width, which must be not more than
12 cm (5 ins).

International matches
Length: minimum 100 m (110 yds)
maximum 110 m (120 yds)
Width: minimum 64 m (70 yds)
maximum 75 m (80 yds)

The goal area
Two lines are drawn at right angles to the goal line, 5.5 m (6 yds) from the
inside of each goalpost.
These lines extend into the fi eld of play for a distance
of 5.5 m (6 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 goal area.
