# Football pitches

A football field is a type of football field. The playing field is rectangular with a length greater than the width, the surface of the field can be natural grass or artificial turf. The size and position of the soccer field's boundary lines are regulated by Law I: Field of Competition in the Laws of Football. Beginning in 2008, to standardize the size of football fields for international matches. , IFAB decided to set the fixed size as: length 105m and width 68m (instead of min and max length from 100m to 110m and min and max width from 64m to 75m as before).

## Structure of a football field

## Limit lines

The two lines that are longer along the length of the pitch are called the goal line.
The two shorter limit lines across the pitch are called the goal line.
Limit lines are not wider than 12 cm.
The line that runs horizontally and divides the court into two equal parts is called the midfield line.
In the center of the midfield line there is a clear point that is the center of the field. Take that point as the center and draw a circle with a radius of 9m15, which is the circle in the middle of the yard.

## Goal area

From the point 5m50 from the vertical post on the horizontal line of each part of the field, draw inwards 2 parallel lines, perpendicular to the crossbar and with a length of 5m50, draw a line connecting the two ends of that line. The area limited by straight lines and horizontal lines is called the goal area.
The world goal has a width of 7.32m and a height of 2.44.
However, applied in Vietnamese football, the width is narrower than 7.12m and 2.4m high.

## Penalty Zone

From a point 16m50 from the vertical post on the horizontal line of each part of the field, draw inside two parallel lines perpendicular to the horizontal line and have a length of 16m50, draw a line connecting those two lines. The area limited by those lines and the horizontal line is called the penalty area.
In each penalty area there is a point with a diameter of 22 cm clearly marked, 11 meters from the center of the goal line, that is the penalty point. Take the penalty point as the center of a circle outside the penalty area with a radius of 9m15, to determine the standing position of the players when taking the 11m penalty.
The penalty area is also commonly known as "the penalty area" or "the 16m50 round".

## Corner flagpole

At each corner of the yard, there is a flagpole at an angle that is not pointed at the top and is at least 1m50 high. Outside the midfield line, at least 1m from the two vertical lines, two flagpoles can be placed.

## Archery Corner

Taking the center as the point where the corner flagpoles are placed, draw into the yard a quarter of an arc with a radius of 1m. This is the position of the ball to kick the corner kick.

## Goals

In the center of each goal line is placed a goal (goal). The goal is composed of 2 vertical columns perpendicular to the horizontal line and equidistant from the 2 corner flagpoles, with a distance of 7m32, (from the inside edge of the column) connected by a parallel crossbar and away from the ground. 2m44 yard (calculated from the bottom edge of the crossbar).
Vertical posts and crossbeams must be of the same size and not exceed 12cm wide. The net usually must be hooked to the post, crossbar and attached to the ground behind the goal
