In terms of terminology, the football field is a flat rectangular area, which is equipped specifically for this game and has an artificial or lawn coverage, depending on the rules of the competition. Mass training of such sites started in the nineteenth century, despite the fact that most of them matches were held at that time for a long time. The area of the football field is different. According to archival documents, the oldest of them in the world is located in the small town of Linlington, which is in the UK.
The strict size of the field for playing football is not defined. Based on the official rules of this sport, the maximum width can be 90 meters, and the minimum - 45. As for the length, it should not be more than 120 and less than 90 meters. Thus, the largest possible area of the football field is 10.8 thousand square meters, and the minimum - 4.05 thousand. As you can see, this parameter varies very much. It should be noted that the official rules of UEFA also say that for international competitions you can use the fields, whose sizes are not less than 100x65 meters.
The size of a football goal has its own standard, which is strictly defined. Their width and height are 7.32 and 2.44 meters. Around the gate there is a goal area of 18.32x5.5 meters. On the left and on the right, it starts at a distance of the same five and a half meters from the gate bars. In each of the corners of the field are drawn circles with a radius of one meter. It is from them that angular blows are performed. Also at 9.15 meters from the corners, appropriate marks can be drawn to determine the place where the players of the opposing team have the right to be during their punching. In the middle, the football field is divided by a line. A circle is drawn in the center. Its radius is equal to the usual 9.15 meters.
Another important parameter that characterizes the football field is the area of the penalty area. Its dimensions are 40.32x16.5 meters. Such an unusual length is due to the fact that from each bar in the sides of opposite boundaries is measured to 16.5 meters. In addition to the size of the gate, the value 40,32 is obtained. On the side of the penalty area, located opposite the goalkeeper's place, an arc of a circle with a radius of 9.15 meters with the center at the penalty point is marked. It should be followed by players in case of a penalty. The size of the penalty area is always the same and does not depend on what the area of the football field.
Behind the site itself, with the aid of an intermittent bar, the so-called technical zone is designated. During the match, reserve players and the coach should not cross its limits. One can not help but emphasize that marking is done by lines, absolutely each of which has a width of 12 centimeters and completely enters the area of the football field. Another interesting fact is that, according to UEFA recommendations, the longitudinal axis of the field should aim northward. The explanation for this is that in this way the influence of bright sun rays on the players' play is reduced as much as possible. In the official rules this is not spelled out, but only in case of fulfilling such a wish the stadium has the opportunity to get into the "UEFA stadium rating".
