What are the hash marks on a football field used for?
Hash marks are the two rows of lines near the center of the field that signify 1 yard on the field. They are located 70 feet, 9 inches from the sidelines. If a player is tackled outside of the hash marks (between the hash marks and the sideline), the following play will start on the nearest hash mark. No play will ever start with the ball placed outside of the hash marks.
