According to a trade organization for the pizza industry, America gets about 100 acres of this food on a typical day:
For those of you yet to take lunch, we think it's the perfect time for a hunger-inducing stat of the day. The Daily tells us, in a profile of healthy pizza purveyor Naked Pizza, that the United States pizza industry "serves about 100 acres of pizza a day." This figure comes from the National Association of Pizza Operators, an organization that aims "to create and foster a community of independent and small chain pizzeria operators and their industry suppliers where doing business with one another is mutually beneficial."

100 acres = 4,356,000 square feet
US Population = 311,624,390
Pizza per person = 0.01398 square feet or 2.01 square inches.
Assuming only 1 person in 1000 is eating pizza that day, that's 13.95 square feet of pizza per person.
