In an athletic game like football, there is often a foul on one team and a free kick on the other team. At this time, in the case of a team that has usually performed a foul play, a defensive wall is formed in the direction of kicking the free kick. In the soccer rules, the player keeps at least 9.15 meters from the free kick point to the defensive wall. In other words, the opponent player can not approach within 9.15 meters of the free kick, and the player does not fall within the prescribed distance.

Judges generally try to catch these rules with experience and skillfully in general, as judges are aware of their own strides and are pre-empathized with practice, assisted by assistant judges, There are cases where the distance is measured through him by using the repeated repeatedly.

However, in a soccer match where there is usually a difference in goal difference, there is often a case where the game is won or lost through a free kick, so that both teams react sensitively to the correct distance, so that the judge can quickly and accurately determine the distance .
