<p>1300 (approx. UChicago class size) / 3100 (approx. Cornell class size) = 42% > 30%.</p>
<p>According to wikipedia, the main Cornell campus is about 3 sq. km. I’m not certain the area in which the Chicago campus falls is much smaller. The difference is that at Cornell everything in that area is “campus”, and it’s very physically distinguishable from the rest of Ithaca, whereas at the University of Chicago there’s a lot of Hyde Park (and a bit of Chicago itself) interwoven with the University of Chicago buildings. If you think of the Chicago campus as everything between Washington Park and Blackstone, and 54th and 61st, the campus really isn’t so much less vast than Cornell. But, yes, it feels very different. And Cornell is much more monumental – the buildings are huge and far apart, and the whole university perches at the top of a huge hill.</p>
