Ceiling fans come in a wide range of blade spans, from small mini fans with a blade span of 18 inches up to large ceiling fans with a 68-inch blade span...and beyond (we even offer fans with an expansive 99-inch blade span!). Choosing the right ceiling fan size will optimize the fan's efficiency and make the fan look right at home in the space.
What Size Ceiling Fan Do I Need?
Ceiling fans are measured by the full size of their blade span (also called blade sweep), which is the diameter of the circle that you see when the fan blades are in motion. Or, in other words, fan blade span reaches from the tip of one fan blade to the tip of the blade directly across.
Ceiling Height Is Important, Too
Depending on the height between the floor and your ceiling, you'll have a different selection of fans to choose from. For rooms with tall ceilings, you need to choose a fan that uses a downrod to suspend it far from the ceiling. For adequate air circulation, the fan blades should hang 8 inches or more from the ceiling. For safety, the bottom of the fan needs to be at least 7 feet above the floor.
Conversely, spaces in the home with limited ceiling-to-floor height (think bedrooms, offices, breakfast nooks, etc.) require a low profile ceiling fan. These fans hug the ceiling and won't hang too low.
What is the difference between 4-blade and 5-blade ceiling fans?
The main difference between a 4- and 5-blade ceiling fan is one of aesthetics and personal taste. However, the laws of physics do dictate a slight difference in performance between ceiling fans with different numbers of blades.
As a rule, as the number of blades goes up, the fan tends to be quieter and circulates less air. Additional blades increase the drag on a ceiling fan's motor and slow it down. This is one of the reasons why industrial fans (like wind turbines) usually have only two or three blades. They can go faster and move more air, and noise isn't so much of a concern.
Many ceiling fans designed for the home come standard with four or five blades. Beyond having a pleasing symmetrical aspect, it's at the 4-blade and 5-blade level that the ideal balance is achieved between the amount of air circulated and amount of tolerable ambient noise.
These days, you are unlikely to notice any major difference in job performance between fans with fewer or more blades. Advancements in overall residential ceiling fan design, balance, and low-drag blade shapes and pitch ensure that ceiling fans with a non-standard number of blades are able to do their job well. Even if you opt for a ceiling fan with an expansive seven blades, you can rest assured it will still perform well.
Do I need a remote control for my ceiling fan?
In some instances, such as when a ceiling fan is mounted on a high or vaulted ceiling, a remote control is the only realistic means of control. In that case, the answer to getting a remote control would be a resounding "yes."
When fan location is not an issue, the main advantage of a remote control is one of convenience. You can control a ceiling fan’s speed, direction and lighting without having to get up and manually pull chains or flip switches on the wall.
There are 2 basic control types available for ceiling fans, each with different benefits:
Remote:
With a remote, a ceiling fan can be controlled from any location within the remote control's range.
Wall Control:
With a wall control, you'll still have to get up and go to the control. However, it doesn't have the potential to get lost and can be installed as easily as a light switch.
