Small ceiling fans for small rooms and large ceiling fans for large rooms, or so they say. While this may sound like an ancient proverb, choosing the right size ceiling fan ensures maximum performance, style, and above all – comfort. The right size ceiling fan will do more than just keep you cool, it can also save you money. Ceiling fans only cost pennies to run compared to air conditioners, allowing you to increase the temperature on your thermostat and save money on your monthly electric bill. But before you buy a fan, you need to know how to size a ceiling fan for your room.
Proper ceiling fan size for your room secures the fan's performance and longevity as well as the comfort and safety of the room occupants. A small ceiling fan in a large room will have to work twice as hard to cool you off, which will result in the motor burning out quickly. A large ceiling fan in a small room will create an uncomfortable amount of airflow. Unless you like replacing your ceiling fan every few months or feeling as if you’re in a tornado, choose a ceiling fan that is proportionate to the room size.
3 Steps to Sizing Your Ceiling Fan
Step 1: Determine How Blade Span Relates to the Square Footage of the Room
To measure a ceiling fan, first determine if you have an odd or even number of blades. If the fan has an odd number of blades, measure from the center of the fan to the end of one of the blades, and multiply this number by two. If the fan has an even number of blades, measure from one end of a blade to the end of the blade on the opposite side.
Ceiling Fan Size by Room Size
Now that you know how to size a ceiling fan, see our ceiling fan size chart below to learn how big a ceiling fan should be based on room size, and how to choose the right size ceiling fan for your room. To determine your room size, multiply the length of the room in feet, by the width of the room in feet, the total is the size of your room in square feet. For example, if your room is 8’ by 8’, the square footage is 64 square feet.
Ceiling Fan Size Guide
|Room Size (In Sq. Feet)||Room Type||Recommended Blade Span|
|Under 144||Bathroom, Breakfast Nooks, Utility Rooms, Small Bedrooms, Porches||Under 42"|
|144-225||Medium Bedrooms, Kitchens, Dining Rooms, Dens, Patios||44-50"|
|225-400||Master Bedrooms, Family Rooms, TV Rooms, Small Garages, Gazebos||Over 50”|
|Over 400||Great Rooms, Large Garages, Basements, and Open Floor Plans||Over 62”|
Step 2: Determine how High to Hang Your Fan: Ceiling Fan Height Requirements
Hanging your ceiling fan at the appropriate height ensures that friends and family members won’t hit their heads on low hanging ceiling fans. It also guarantees that they'll be able to feel the airflow the fan produces since fans cool people, not rooms. There should be a 7-foot minimum distance between your ceiling fan’s blades and the floor. If you have low ceilings, or if you have regular size ceilings and you just happen to be really tall, install a low profile ceiling fan.
Ceiling Fan Height Chart
This table shows how high your ceiling fan should be based on your ceiling height, and whether or not the ceiling is sloped.
|Ceiling height < 8 Feet||Choose a low profile ceiling fan. 18" Minimum distance blade to wall. 7' minimum distance blade to floor.|
|Ceiling height > 9 Feet||Choose a ceiling fan downrod. 18" Minimum distance blade to wall.|
Step 3: Determine Whether You Need a Downrod
High ceilings require downrods. A high ceiling is defined as any ceilings over 9 feet high. More information can be found on our More Helpful Resources
