At it's most expansive, the Roman Empire was about 5 million square kilometers (2 million square miles). The United States is far larger, at 9.8 million square kilometers (3.8 million square miles).
That actually splits the ancient city of Rome into two capital cities of two modern countries. There are no material boundaries that isolate each part; only politically within the core of Rome there are 0.44 sq km (109 acres) that are a different country. Therefore one city, Rome, is shared between two countries.
