America's Largest Pizzas Slideshow

Slide 1 of 10
Pizza Ranch Restaurant — Iowa Falls, Iowa

Pizza Size: 129-by-92 feet (though according to some sources, it was even bigger at 129-by-98 feet), 50,000 slices

In June 2005, Bill Bahr, assistant manager of the Pizza Ranch in Iowa Falls, Iowa, attempted to break the Guinness World Record for the world’s largest pizza. The pie totaled 50,000 slices — not quite large enough to top the reigning champ. With the help of 200 volunteers, the entire pie took two hours to assemble.
