The rules behind the numbers

  • Blade span by room: Hunter gives under 29 inches for spaces under 5 by 10 feet, 39 inches up to 8 by 10, 42 up to 10 by 10, 52 up to 10 by 20, and 56 or more up to 20 by 20 and beyond [1].
  • A second opinion: Minka-Aire sizes up for the same room: up to 42 inches for 40 to 60 square feet, 44 to 50 for 70 to 90, 52 to 58 for 100 to 150, and 60 and up past 160 [2]. Both are general airflow guides, and Minka says style can sway the choice [2]. Between the two is a safe buy.
  • Mount: a flush or low-profile mount for ceilings around 8 feet; a standard mount with a downrod for ceilings around 9 feet, so the blades hang 8 to 9 feet from the floor [1]. Sloped ceilings over 34 degrees need a sloped ceiling adapter [1].
  • Big rooms: for very large rooms, more than one fan is an option [2]. The calculator suggests it past 400 square feet, or for a long room over 200 square feet that's twice as long as it is wide.
