Dimensions of an American Football Field
A football field's dimensions can vary depending on the level of play (college football, high school football, NFL). Most fields will share the same length and width, but the main difference is the distance in between the center hash marks.
Football Field Dimensions
A regulation football field's dimensions are 160 feet wide (53 yards) by 120 yards long. The field of play accounts for 100 yards and each end zone accounts for 10 yards, adding up to a total length of 120 yards. The field will be split up by white lines that run the entire width of the field every 5 yards and are marked by numbers every 10 yards.
Hash marks are used to measure the yardage on every down. Oftentimes the distance between the hash marks, the two sets of dashed lines that run down the middle of the field, will vary in distance depending on the league and level play.
- High School has marks are 53 feet, 4 inches apart
- College football hash marks are 40 feet apart
- NFL hash marks are 18 feet, 6 inches apart
The End Zones
IMPORTANT: Many people will refer to a football field as being 100 yards long, however, this is incorrect because it does not account for the addition of the end zones. Remember that a football field is actually 120 yards long.
