James Madison University (JMU) is a mid‑to‑large public university with a campus of about 721 acres and around 22,000 students in recent years. That makes it a sizable, but not mega‑scale, U.S. campus.

Campus size

  • JMU’s main campus in Harrisonburg, Virginia covers roughly 721 acres (about 2.9 km²).
  • The campus includes more than 140 major buildings spread across historic “Bluestone” areas and newer expansions.

Student population

  • Recent data show total enrollment around 21,000–22,000 students , combining undergraduate and graduate programs.
  • Undergraduates make up the vast majority, with roughly 20,000 undergrads and under 2,000 graduate students.

How “big” it feels

  • With over 20,000 undergrads , JMU feels like a large university socially and academically, with many majors, clubs, and activities.
  • Physically, a 700+ acre campus means plenty of walking and distinct areas (academic, residential, athletics), but it is still walkable compared with sprawling multi‑campus systems.
