Love this fan - bought two.  One for my son's room and one for the TV loft - it is powerful for its size, but would probably be best in a 12x12 room.  All of our rooms are 16x16+  with 10-foot ceilings so it would probably make more of a breeze in a 12x12 with 8-foot ceilings - consider that, but otherwise this thing is perfect in design and look for our farmhouse renovation.
