Medium sized ceiling fan


What ceiling fan size do I need? This is a common question when shopping for ceiling fans. Since the fan size you need depends on the room, it's essential to know how big or small your space is and what size ceiling fan will best fit its dimensions. Here's our guide to help you choose the right ceiling fan size by room and other considerations.

What is a Standard Ceiling Fan Size

Ceiling fan size refers to the span or diameter of the blades, that's, from one tip to another or, depending on the number of blades, double the distance from the blade tip to the fan's center. Manufacturers make these fans in different sizes, ranging from small to large. Standard ceiling fan sizes are given below.

Ceiling Fan Small Size

Ceiling fan sizes for small rooms range from 29" to 36" in diameter or slightly higher. These smaller fans are perfect for bedrooms, office cubicles, and bathrooms. Most of these ceiling fans are designed with low-profile motor housing and a compact blade design to fit into tight spaces efficiently.

Ceiling Fan Medium Size

Medium size ceiling fans range from 36" to 54" in diameter. They are perfect for medium-sized rooms such as living rooms, bedrooms, dining rooms, and small family rooms. These fan ceilings use a larger motor to accommodate the increased blade span, creating more airflow and circulation.

Ceiling Fan Large Size

Large ceiling fans usually range from 50" to 60" in diameter. These are best installed in larger living rooms or outdoor patios and decks. Extra-large ceiling fans have a blade range of 72" to 120". These fans are mainly designed for open-concept areas and large commercial or industrial spaces.

How to Measure Ceiling Fan Size

As we indicated earlier, ceiling fan size is measured by the blades' diameter. These dimensions may also be referred to as a fan's span or blade sweep and are indicated in either inches or centimeters.

How are Ceiling Fans Measured?

For fans with an odd number of blades, the dimensions are measured from the tip of one blade to the center of the fan. This measurement is then doubled. If the number of blades is even, measure from one tip to another. Ceiling fan measurements will usually be indicated on the fan's packaging or product specifications.

Ceiling Fan Sizes in MM

Ceiling fan sizes are also indicated in millimeters (mm). This is usually the case when looking for a European-style fan. For example, a 750mm ceiling fan would roughly equate to a 30" American-sized fan based on the blade span measurement.

Ceiling Fan Sizes in inches

Inches are the most common way to measure ceiling fan size. As previously mentioned, the diameter is usually indicated on the product specifications. The most common sizes are from 29" to 72" or larger, as earlier indicated, too.

How to Choose Ceiling Fan Size

Now that you know how ceiling fan size is measured, you should be able to find the right size for your space. Here are some general measurements you can follow to guide you on what size ceiling fan to buy. Use them to pick a fan that will fit your space.

Ceiling Fan Size By Room

Because different rooms have different ceiling dimensions, the room type can determine your ceiling fan size. Here, we refer to the estimated fan sizes based on the other rooms in a home.

Ceiling Fan Size for Bedroom

A 29 to 36- inch ceiling fan is usually recommended for bedrooms. These are great for smaller spaces. For larger rooms, blades up to a 48" fan should suffice. Note that for more oversized bedrooms, you may need more than one fan to ensure even air circulation throughout the room.

Ceiling Fan Size for Living Room

Living rooms are generally larger than bedrooms, so a 48 to 56-inch ceiling fan should create enough airflow. The size of the living room and the height of your ceilings will ultimately determine the right size for your space.

Ceiling Fan Size Kitchen

You may opt for a smaller fan in the kitchen, such as a 29 to 42-inch ceiling fan with multiple blades to create more airflow. However, if your kitchen is large and has high ceilings, you may want to choose a larger fan up to 48" or more.

Ceiling Fan Size vs. Room Size

While you can size your fan's size based on the room type, that may not always be the best approach. For an accurate estimate of ceiling fan size for room size, we recommend considering both the size of the room and the height of your ceilings.

Finding ceiling fan size by room size means sizing for homes, offices, businesses, schools, and any other type of building. Generally, the higher the ceilings in a room, the larger your fan should be.

To find the right size for your fan, measure the length and width of the room. Then, use this information to calculate your ceiling fan size, as provided below.

Ceiling Fan for 10x10 room

For a 10x10 room, the ceiling fan size should measure between 36" and 44". This will create enough airflow for the small space while ensuring the fan is not too large or overpowering.

Ceiling Fan for 10x12 room

This is a 120-square-foot room, so your best fan should measure between 36" and 44". This will provide an optimal air circulation balance without being too large for the space.

Ceiling Fan for 12x12 room

Still, if you have a 12x12 room, your best ceiling fan size will range between 36" and 44". This should create enough airflow for the medium-sized room while still fitting comfortably in the space. However, if your area's climate is warmer, you may want to size the fan higher — up to about 48 inches or so.

Ceiling Fan for 13x13 room

For a 13x13 room, you'll need a fan that measures between 44" and 54". A 44 to 54-inch ceiling fan will create enough air circulation for the larger space while not occupying too much of your ceiling's visual area.

Now that you know how to pick ceiling fan size, you can size yours. Remember, the right size means proper air circulation and aesthetics.


Choosing the right ceiling fan size for your home or another place can make a difference, whether in terms of air circulation, energy efficiency, or overall comfort. Using the guidelines provided here, you determine the optimal fan size for any type or size of the room. That includes sizing your fan using both room measurements and ceiling height.
