A 52-56 inch fan
For a 200 sq ft room, a 52-56 inch fan moves air well. Big or long rooms often do better with two fans than one oversized one.
Blade span by room size is the main rule; also keep blades 7-9 ft off the floor and 18+ inches from walls. High ceilings need a downrod.

Oversized is its own kind of broken
An air conditioner with too much capacity short-cycles, never pulls the humidity out, and wears itself down early. In a Carolina summer that matters more than the raw tonnage.
How this is worked out
No hidden fudge factor. This is the whole calculation.
- You enter room area (sq ft).
- That runs through a rule of thumb calibrated for the North Carolina climate.
- It is a starting point for the conversation, not the calculation a licensed pro performs.
