Yard lines are a place on an American football field marking the distance from the line of scrimmage to the closest goal line.[1]

White markings on the field identify the distance from the end zone. Inbound lines, or hash marks, are short parallel lines that mark off 1 yard (0.91 m) increments. Usually, every 5 yards (4.6 m) they run the width of the field. A one yard wide is placed at each end of the field; this line is marked at the center of the two-yard line in professional play and at the three-yard line in college play. Numerals that display the distance from the closest goal line in multiples of ten are placed on both sides of the field every ten yards.[2][3][4] Lines marked along the ends and sides of the field are known respectively as the end lines and sidelines, and goal lines.
