Size The size of a fan probably has the most effect on how well it cools down your room. To figure out the right size for your space, get out the measuring tape (or your builder's floorplan) and measure your room. Check out these measurements, from Garbe's:
- For small rooms up to 64 square feet, get a 29" fan.
- For rooms up to 100 square feet, a 42" fan.
- For rooms up to 225 square feet, a 52" fan.
- And for large rooms up to 400 square feet, one 56", one 60" or two 52" fans will be best.
Placement After you've determined your fan is the right size for your space, placement is key. If you're not sure of where or how high to hang the fan, check out these guidelines:
- Place the fan as close to the center of the room as possible. If you have an irregular space (like an L-shaped room), consider mentally splitting the room and hanging two fans sized for each space.
- The blades of your fan should be at least 18 inches from the nearest walls.
- The optimal height from the floor for your fan depends on the height of your ceiling. After you've figured out the height of your room, check out this graphic, from Garbe's, to find the optimal down rod length (the bar that travels from the fan's base to your ceiling) to hang your fan:
- Fans should never be hung lower than 7 feet from the ground. If your room is shorter than 8 feet, consider a low-profile venting fan that's designed to hang flush with the ceiling.
