Is Stanford the 2nd largest university in the world?

<p>OK, so I'm confused. When my S and I visited the campus during Admit weekend one of the tidbits of information we heard was that Stanford was the largest univerisity in the US and the second largest in the world. Supposedly, the largest was the University of Moscow and there's some doubt to that claim because evidently they counted some vertical square footage, since its a city campus and we don't. But Stanford is approximately 8200 acres, yet Duke is 8600 acres. So are we the biggest in the US or not?</p>

<p>Thanks</p>
