The lines are part of the soccer field when the ball is in play. We know that the Laws of the Game require that a ball cross wholly over the touch line to be in touch (out of play), or wholly over the goal line within the goal to be a goal (fouls or other infractions of the Laws of the Game aside).
The lines on a soccer field mark different sides and positions within the field. These are made with a chalk or with a paint.
The lines that mark a soccer field are touch lines, goal lines, the halfway line, the center circle, corner arcs, goal area lines, penalty area lines, and penalty arcs.
The touch lines.
If the ball hits the line it's a FAIR BALL
In soccer, the boundary lines are the touchlines (sidelines) and the goal lines (end lines) that define the field of play. The ball must completely cross these lines for the ball to be considered out of play.
Also known as the end line, the goal line is the line that runs the width of the field. It runs across the front of the goal and when the ball passes the end line within the goal posts, a goal is scored. If the ball passes the end line outside of the goal posts, the ball is out of bounds. Depending on who touched it last, a corner kick or goal kick will restart play.
yards all da way
The lines that mark a soccer field are touch lines, goal lines, the halfway line, the center circle, corner arcs, goal area lines, penalty area lines, and penalty arcs.
Soccer goal posts must not be more than 5 in (12 cm) and must be the same as the width of the lines on the field.
The boundary lines at the ends of the field are "goal lines" or "end lines". The long boundary lines at the sides of the field are "touch lines" or "side lines". In FIFA Laws of the Game, Law 1 describes the field of play in more detail.
