Fan Sizing Guide for Smart Homeowners

These days, ceiling fans come in a large variety of sizes. This is why aside from the number of blades, homeowners are often confused about what size of a fan they should pick.

Fan Sizing Guide

This is a crucial decision, as it will determine the efficiency of the product you’ll buy. For example, a small ceiling fan of the best quality will not perform accordingly due to the large size of the room and vice versa.

Here, it’s important to note that the dimensions of a fan are determined by the diameter of its sweeping circle when the blades are in motion. Now, keeping that in mind, here are some fan sizes that you can find in the market: 18”, 36”, 52”, 68” and even larger.

What size you’ll buy should be based on the following considerations:

Fan sizing considerations

  • Type of the room: The most generalized way to choose the size of a ceiling fan is by the typology of the room. People tend to choose smaller fans for kitchens and bathrooms, medium-sized ones for bedrooms, and large ones for the living rooms. However, this selection is completely hypothetical, and can be wrong.
  • Size of the room: By knowing the actual size of the room, you’ll be better able to determine what diameter of a fan you should go for. If your area adds up to 75 square feet, you can choose a 29”-36” fan depending on the actual dimensions of the room.

Any area that adds up to 175 square feet (usually bedrooms, dining spaces, kitchen, etc.) requires a fan size of 42”-48”. For spaces up to 350 square feet (i.e., living rooms, dens, media rooms, or other oversized spaces) can only be outfitted with 52”-56” fans. Anything above requires a 60” or larger ceiling fan.

  • Height of the ceiling: The height of the ceiling is another factor that has to be considered while buying a ceiling fan of the right size. Here’s a bit of a science lesson in this regard:

Ceiling fans work by pushing air down to the floor level by pulling on air that’s above the blades. The air on the ground-level circulates upward again, so the process can continue. Therefore, the space between the fan blades and the ceiling surface has to be ample enough to perpetuate good airflow.

Basically, the stem of your fan needs to be long enough to leave enough space between the blades and the ceiling. Other than that, you also need to have 7 feet of clear-height from the bottom of the fan to the floor for proper standing room.

  • In case of solid obstructions: If the fan is too large (such as when there isn’t enough room between the blades and the walls), there will be a vacuum effect that will result in poor air circulation. Similar is the case if there are any large physical obstructions between the blades and the wall. This will also help you determine the size of your fan.

These are your fan sizing considerations and size chart. We hope this helps you find the perfect ceiling fan for your homes!
