Ohio State gets small fast when you realize it’s actually several small compact colleges adjacent to one another.
Fisher is on the north end, adjacent to engineering. Most students spend most of their time in a relatively small area of campus.
A fairly far trek would be a south east dorm like Park Stradley to Hitchcock a north engineering building. Google has that walkable in 14 minutes, but a youthful stride across the Oval manages it in 10.
Blackburn, a north campus dorm to Fisher is a 4 minute walk on google maps.
There are also recreational and dining facilities sprinkled throughout campus and the north campus options are nice.
