Which has smaller undergraduate classes, Stanford or Amherst?

The central tradeoff is Amherst’s consistently intimate undergraduate classroom environment versus Stanford’s far broader course selection and research scale. Amherst is a small liberal arts college built around discussion, writing, and close faculty contact across the curriculum. Stanford offers many small seminars and strong access to professors, but its introductory and popular major courses can be substantially larger.

At Amherst, nearly all teaching is directed toward undergraduates, and students commonly encounter seminar-style classes early rather than waiting until upper-division work. Its open curriculum can also make it easier to build an academic path around small, interdisciplinary courses and sustained relationships with professors.

At Stanford, class size depends more on the department and course level. Humanities, social science, language, and specialized upper-level classes may be quite small, while gateway courses in computer science, economics, engineering, biology, and other high-demand fields can include large lectures supported by sections, teaching assistants, and office hours. Students who actively seek seminars, research groups, and faculty mentorship can create a personal academic experience there, but it takes more intentional course selection.

For small undergraduate classes as a top priority, Amherst is the clearer choice. Stanford can provide excellent close interaction, particularly after the introductory sequence, but Amherst makes that kind of discussion-based learning the default rather than an option students have to seek out.
