College students are willing to take classes in a 400-square-meter classroom. In university classrooms, large classrooms are all stepped classrooms, which can accommodate 200 to 260 people, and small classrooms can generally accommodate 60 to 100 people. Generally speaking, the area of the big classroom is 400 square meters, and the area of the small classroom is 200 square meters. University classrooms include small professional classrooms, multimedia classrooms, terraced classrooms and small auditoriums. And there is no fixed standard, and every school will have small differences. The most common ones are 7-8 meters long and 5 meters wide.
