How long is an NFL football field?

An NFL football field is 120 yards long (360 feet). From goal line to goal line, the field is only 100 yards (300 feet) long, but once each ten-yard deep end zone is factored in, the field adds up to 120 yards (360 feet) in total length.

Hash Marks

Almost all American football fields will be the same length of 120 yards (360 feet), but the main difference between different levels of football is the placement of the hash marks that run up the sidelines. Hash marks are small vertical lines that run parallel to the endzones, and are used to measure yardage on every down. Hash marks all measure 1 yard apart, are placed in between longer white lines that appear every 5 yards, and stretch the entire width of the field. The NFL’s hash marks are placed 18 feet and 6 inches apart, which is perfectly in line with the goal posts, but shorter than both the college and high school distances.
