Football Field Dimensions and Goal Post Sizes: A Quick Guide

In American football the standard field dimensions are 120 yards long and 53 1/3 yards wide. The last 10 yards of length on either end of the field are considered "end zones" in which a player scores. These dimensions are consistent for football played at the high school, college and professional (NFL) level.

The total length of a football field is 120 yards. The playing field is 100 yards (360 feet) long, and each end zone is 10 yards (30 feet) deep. The field is marked with a yard line every 5 yards, and every 10 yards is marked by a field number. The hash marks are 1 yard apart, used to mark each down when the ball is between the yard lines.

Width of a Football Field

The standard football field is 53 1/3 yards, or 160 feet, wide. The primary difference among different levels of play is the space between the two sets of hash marks:

  • 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 the right hash mark.
