So how large (long and wide) is a regulation football field, exactly?

Here’s a inside wall on just how the dimensions play the end at every level, from high institution football to the NCAA and also on as much as the NFL.

You are watching: A football field is 100 yards in length how many inches long is a football field

There are two constants, throughout the level the competition: 120 yards (360 feet) of length and also 53 1/3 yards (160 feet) the width. The playing field is 100 yards long, through a 10-yard-deep end zone on every side. In total, a football ar covers 57,600 square feet, or the tantamount of 1.32 acres. Hash marks measure each that the 100 yards, through a yard line in ~ every 5 yards and also the ar number noting every 10 yards (on both sides, close to the sidelines).


Those hash marks were an initial seen on professional football fields as a result of the very first rule alters in 1933, noting one that the an initial major deviations from college fields.

Each beat starts top top the nearest hash marks come the end of the previous pat — if claimed play finished outside the hash marks, including on the sideline. Thus, v less an are between sets of hash point out and more space in between the hashes and also the sidelines, there is much much more real legacy for ball carriers come turn and maneuver about defenders.


The width, similarly, is the very same for high school, college and also NFL fields. The only variable that changes by level is the distance between the 2 sets the hash marks. Because that high school football, the hash marks room 53 feet, 4 inch apart. The separation decreases to 40 feet in college and also shrinks come 18 feet, 6 customs in the NFL. 

When it involves the goal posts, the crossbar is 10 feet high and also the write-ups on either side are an additional 20 feet tall, bringing the full height to 30 feet. In both NCAA and also NFL play, the goal posts are 18.5 feet apart, when high institution goal posts are 23 feet, 4 inch apart.


For over 40 year after those early rule changes took effect, the goal posts were situated on the goal lines. Finally, in 1974 ~ scores of — and which caused — collisions, the goal short articles were moved to the ago of the end zones (in Canada, goal short articles still sit ~ above the score lines).
