Why are fan blades twisted?

The main effect of blade twist is to ensure that every section of the blade operates at the desired incidence angle with the incoming flow. The relative wind seen by a blade airfoil is the vector sum of the incoming absolute velocity and the velocity of the blade generated by its rotation.

Is a 52 inch fan too big for a 12x12 room?

The ALA recommends a 29- to 36-inch fan for a room up to 75 square feet, such as a bathroom; a 36- to 42-inch fan for a medium-size room up to 144 square feet; and a 50- to 54-inch fan for a room around 225 square feet; 54- and 60-inch or larger fans are available for larger spaces.
