Yes, by actual land size. DIA covers roughly 55 square miles. It is the 3rd largest, by land size, in the world. As for passenger count, it's #5 in the US but comes behind the likes of ORD, IAH, and ATL. It is up there in daily operations as well but not the top. Maybe one day DIA will move to a "superhub" status.
