Why is my dorm room a different size?

Sizes change by school, building and room type, and older halls vary room to room. These figures describe room types as schools publish them, not any one room, so check your own hall before you buy.

Where thesenumbers come from.

Only sizes a college publishes. Estimated sizes are left out, so 1,116 room types across 566 halls at 46 schools count.
Singles, doubles and triples only. Graduate and family housing, studios, quads and any listing over 300 sq ft per person are left out: those describe a whole apartment, not a room.
Typical means the median, the middle room, so a handful of big suites can't skew it. The average (mean) is shown too.
Sizes describe a room type as the school publishes it, not your exact room. See how we measure dorm rooms.
