How Many Acres is a Football Field?

Football Field Dimensions

High school, college and NFL football fields are the same size. A standard football field is 120 yards long. The playing field is 100 yards (300 feet) long, and each end zone is 10 yards (30 feet) deep. The field has a uniform width of 53 1/3 yards (160 feet).

If you calculate the entire area of a football field, including the end zones, it works out to 57,600 square feet (360 x 160). One acre equals 43,560 square feet, so a football field is about 1.32 acres in size.

What are The Numbers and Lines on the Field?

Football Yard Line Markers

The field is marked with a yard line every 5 yards, and every 10 yards is marked by a field number. Each half of the field has a numbered 10-, 20-, 30- and 40-yard line, and a numbered 50-yard line splits the field evenly in the middle.

There are also the hash marks, those shorter lines that run between the 5-yard lines the whole length of the field. The hash marks are one yard apart. The primary difference between high school, college and NFL fields is the distance between the two lines of hash marks. Here's how much space is between the lines of hash marks at each level:

  • High School - 53 feet, 4 inches
  • College - 40 feet
  • NFL - 18 feet, 6 inches

All plays begin on or between the hash marks, depending on where the previous play ended. For example, if the previous play ended along the right sideline, the ball will be placed on a right hash mark. This is done so teams don't have to run plays while extremely close to one sideline, which could provide an additional advantage to the defense.

How Big are The Goalposts?

Football Goal Post Dimensions

The football goal crossbar is 10 feet high, and each side post is an additional 20 feet high, making the entire structure 30 feet high. High school goal posts are 23 feet, 4 inches wide, while NCAA and NFL goal posts are 18 feet, 6 inches wide. At the NFL level, the width of the goal posts matches the width of the hashmarks.
