What is the touchline in soccer?
The touchlines, also called sidelines, are the long lines on each side of a soccer pitch. When the ball completely crosses the touchline, the team that did not last touch the ball is awarded a throw-in to restart play. For this reason, the area just outside the touchline should remain clear of any equipment, signs, or other players, because it can see a lot of action.
The two touchlines and the two end lines form what is called the field of play. The lines themselves are considered inbounds, but beyond these lines is out of bounds. It also includes the area on the pitch beyond these lines where the manager, staff, and players are allowed to be during the match.
The touchlines are between 100 yards (90 meters) and 130 yards (120 meters) long. They are the longer set of lines on a soccer pitch. The touchlines and end lines make up the boundaries of the soccer pitch. The end lines are between 50 yards (45 meters) and 100 yards (90 meters) long.
