Call it what you will, a football field is a little over an acre. So we have at least 200 football fields, correct?

The Question:
I'm trying to visualize an acre. Is it about the size of a football field?
The Answer:
Yes. Often an acre of land is compared to a football field. In reality, an acre is equal to about 76% of a football field, when you consider both end zones.
A football field (including the two end zones) is 360 feet long and 160 feet wide for a total of 57,600 square feet. When you take away the two 30-foot-long end zones at each end, the field is 48,000 square feet, making an acre about 91% of the field.
An acre, which is a common measurement of land area, is equal to 43,560 square feet.
