If you live in a warm climate, someplace that experiences particularly hot summers, or simply have a “stuffy” room in your home, you may be so accustomed to the sights and soothing sounds of ceiling fans that you forget they exist. But although these (almost) silent ventilators are often hailed more for their functionality than their form, they certainly deserve some careful thought to choose the perfect one.

Fans: A Fixture in Global Comfort

The first ceiling fans, originating in India around 500 B.C., were made of single, large leaf-shaped paddles that manually moved air back and forth. In 1882, the motorized ceiling fan was invented, which enjoyed massive commercial success in a pre-air-conditioning world. After falling out of style in the U.S. in the 1960s, indoor ceiling fans made a comeback in the decades that followed due to a focus on energy efficient cooling.

Ceiling fans work to move and circulate air throughout the room with rotating blades, producing a “wind chill” effect that makes a person feel cooler and more comfortable, without having any actual impact on the air temperature of the room. Fans with blades that reverse direction can also help distribute heated air to a cold room.

When it comes to installing a fan, not just any old set of rotating blades will do, though. It’s important to pick the proper size and type of ceiling fan. There are many different sizes, materials, and styles of ceiling fans out there, each made to pair with your room’s specific décor and dimensions.

Why is the size of your ceiling fan so important? Not only will the size of the fixture affect the aesthetic of the room, it can also influence its efficiency and effectiveness. After all, adding a tiny ceiling fan to a massive room is akin to trying to “boil the ocean” – the impact will be unnoticeable and unmeasurable.

What size ceiling fan do I need?

To determine the perfect size, get out the tape measure and find the shortest wall in the room where you want to hang the fan. It shouldn’t be surprising that rooms with shorter walls require fans with shorter blades. Once you have your measurement, consult the chart below to determine the recommended size for your new fan. (Note: the fan size refers to the full diameter of the circle the blades spin in – or the span from the tip of one blade to the tip of the blade on the opposite side.)

Type of room	Length of shortest wall	Recommended fan size
Small bedroom, nook or utility room	8’ or shorter	30”
Bedroom, dining room or kitchen	9-12’	41-50”
Large bedroom, family room or den	12-16’	51-60”
Great room, large living room	16’ or longer	61-70”

You may also consider the total square footage of the room as a factor. For example:

• A 36” ceiling fan will cool a room with an area of 144 square feet.
• A 42” ceiling fan will cool a room with an area of 225 square feet.
• A 52” ceiling fan will cool a room with an area of 325 square feet.

In addition to the wall length and total square footage of your room, be aware of the ceiling height. You’ll want your fan to hang 8-12” below the ceiling at the very least, and no lower than 7’ above the floor. Ceiling fans often come with varying length down-rods that allow you to hang the fixture higher or lower depending on your room’s ceiling height.

Types of ceiling fans

Whether you’re buying an outdoor ceiling fan for a patio, or an indoor ceiling fan for a bedroom, den or kitchen, you should carefully consider your room and your needs before choosing a specific type or style. From modern, three-blade works of art to functional, five-blade fans, here are some of our favorite picks… you could say we’re big fans.

Casablanca Orchid

Although it has a smaller diameter, 30,” that’s perfect for diminutive rooms, this pick is definitely not short on style. The blades were designed to mimic the beauty and asymmetrical shape of orchid petals in full bloom. Use the down-rod as is or expand it for rooms with vaulted ceilings.

Casablanca Valby

A beacon of mid-century modern design, this 54” ceiling fan features clean, simple lines, a warm, natural wood finish and a functional design. If you’re in need of a ceiling fan with lights, you’ll like the LED light kit, which will ensure your room is well-lit.

Casablanca Correne

You just might be hypnotized by the fluid movement of this Scandinavian-inspired fan when it’s in motion. The smart and sensible combination of wood, metal and glass make it a match for many different decorating styles, and its 56” size makes it perfect for large bedrooms or family rooms.

Fanimation Spitfire

With an exquisite three-blade design and a variety of rich finishes to choose from, the 60” Spitfire is the choice for those with discerning tastes. Want a high-tech home?

Fanimation Zonix

Your contemporary bedroom needs the style and sophistication of the Zonix 54” ceiling fan. The minimalistic design features three blades that are available in bronze, copper or nickel finish, to closely match your room’s décor.

Fanimation Xeno Wet

If you have a unique porch or patio, using outdoor ceiling fans for your space is a smart move. Not only will you keep your cool while relaxing outside, the 56” Xeno fan will ensure you look cool doing it.

Don’t see what you’re looking for above? In addition to many other styles, there are also special types of ceiling fans with various features to fit your room’s needs.

Flush-Mount Ceiling Fans

This type of fan is the perfect fit for small spaces with standard ceilings. The low profile of the fan will help you adhere to the 7’ rule (your fan should be at least 7’ above the floor, as mentioned above), even in rooms with 8’ ceilings.

Chandelier Ceiling Fan

You’ve heard of dining room chandeliers, but what about chandelier fans? From stained glass to sparkly crystals, chandelier ceiling fans offer more style and personality than traditional wooden or metal blade fans. Many chandelier fans are so beautiful and brilliantly designed, you won’t even notice the blades! Because of their ornate nature, they work well in well-decorated dens, game rooms or great rooms.

Now that you know the answer to the question, “What size ceiling fan do I need?” all that’s left is for you to go shopping for a new set of blades!
