STANDARD SIZE OF FOOT BALL GROUND

The size of a football (soccer) field is about 100 metres long and 60 metres wide, but in official games there are regulations about the minimum and maximum dimension. In the world football the most official dimensions are those that had been decied by FIFA (The Fédération Internationale de Football Association).
According to the stipulations from FIFA a football field should have specific minimum and maximum dimensions:

The length (touch line) has to be minimum 90 metres (100 yds) and maximum 120 metres (130 yds).
The width (goal line) has to be minimum 45 metres (50 yds) and maximum 90 metres (100 yds).
For international matches the rules are somewhat stricter:

The length has to be minimum 100 metres and maximum 110 metres.
The width has to be minimum 64 metres and maximum 75 metres.
In 1800s, the fields could be up to 100 yards wide and 200 yards long. The boundaries were only marked by flags until 1882 when boundary lines, as well as a halfway line (the center circle became a standard five years later), on the turf were enforced.

The goal area
The goal area is the small box inside the penalty area. The FIFA rules stipulates that the distance from each goalpost to the lines that goes parallel with the touch line should be 5.5 metres. When the size of a standard goal is added it makes the distance between the lines 18.32 metres.
The penalty area
The penalty area is the bigger box close to the goal that integrates the goal area and the penalty mark (it was introduced in 1887 and was complemented by D-shaped curve in 1937). The lines that extend into the fields are 16.5 metres and they have a 40.32 metres distance from each other.

The penalty mark is 11 metres from the goal line and centered on the fields’ goal line.
