How many acres make an American football field?

Answer 1

A football field, within the "in-bounds" area of the field, is 0.9 acres -- starting at the goal line and ending at the 10 yard line on the other end of the field. When you include the full length of the field plus the end zones, a football field is 1.32 acres.

A high school football field measures 360 feet long by 160 feet wide (playing area). This equals 57,600 square feet which translates to 1.32231 acres.
