How To Measure Pedestal Fan Size?

Whether you are buying a new pedestal fan or looking forward to understanding the science behind airflow produced by the fan blades, learning about the basic fundamentals plays a crucial role. Everything matters, from the rotation of the blade in a minute to the size. The fan blade size is usually measured in diameter and then airflow is calculated based on the rotation count.

If you have an old fan and you want to learn about the airflow by checking its size, you might feel confused that how to measure the exact diameter. Even, there are plenty of questions fogging into the mind about accuracy. To take a precise guess, you can head over the product’s description detail. But, what if you want to do it manually on your own? Well, here is a complete method.

Pedestal Fan Size Measurement

Pedestal Fans in India

For Even Fan Blades – 2, 4, 6, and so on

When there are fan blades in the even count, measuring the diameter seems like an easy choice. Most pedestal fans have two or four blades, which can make it easier for anyone. To know about the fan size –

  • Start by removing the protective net. It is usually easy to unlock by unscrewing the screws.
  • After that, get a measuring tape and check the length from tip to tip. You should do it from one end to the farthest tip.
  • After that, you have the readings of pedestal fan blade size.

However, this method won’t work when you are doing the same with a pedestal fan, which has an odd number of blades.

For Odd Fan Blades – 3, 5, 7 and so on

If your pedestal fan has three or five blades, then it might be difficult to rely on the previous method. So, there is an easy method that will work for both, odd and even.

  • After removing the protective net from the pedestal fan, you can measure the length from one tip to the centre of the fan.
  • Make sure that you get the accurate reading by checking it twice. Once you have the readings for the single blade, you can multiply it by two.
  • Wollah! Now you have the exact diameter of the fan blade.

In situations when you are buying a new pedestal fan, then learning about the height from the ground, fan blade size, its shape and RPM will help you get the exact detail of what to expect from your new purchase.

Here’s a comprehensive guide to measure pedestal fan size in India:

  1. Blade Size: The blade size of a pedestal fan is one of the most crucial factors to consider. It determines the fan’s air-circulating capacity and cooling performance. In India, pedestal fans typically come in various blade sizes, such as 16 inches, 18 inches, and 20 inches. The size refers to the diameter of the circular path that the fan blades follow as they rotate. To measure the blade size, use a tape measure or ruler and measure from the tip of one blade to the opposite tip, passing through the center. Ensure you measure across the blade’s curve to get an accurate measurement.

  2. Height: Pedestal fans are known for their adjustable height, which is essential for directing airflow at different levels. To measure the height of a pedestal fan, extend it to its maximum height. Then, measure from the base of the stand to the top of the fan head. Keep in mind that the height is adjustable, so if you need a fan that can reach specific heights, make sure to consider this aspect.
  3. Oscillation: Pedestal fans in India often feature an oscillation function that allows the fan head to rotate horizontally, distributing air evenly across the room. To measure the oscillation range, activate the oscillation function and measure the maximum angle that the fan head can move from side to side. This measurement helps you determine the coverage area of the fan’s oscillation feature.
  4. Airflow: Another critical factor to consider when measuring a pedestal fan’s size is its airflow capacity. Airflow is usually measured in cubic feet per minute (CFM) and can vary significantly from one fan to another. The higher the CFM, the more air the fan can circulate, providing better cooling. When choosing a fan, check the product specifications for the CFM rating and ensure it aligns with your cooling needs.
  5. Base Diameter: The base of the pedestal fan provides stability and support. To measure the base diameter, simply use a tape measure or ruler to measure from one end of the base to the other in a straight line. A wider base diameter typically provides better stability, preventing the fan from toppling over.
  6. Weight: Although not directly related to size, the weight of a pedestal fan can be an important consideration, especially if you plan to move it around frequently. Lighter fans are easier to transport, while heavier models tend to be more stable. To measure the weight, use a scale or check the product specifications provided by the manufacturer.

In conclusion, measuring the size of a pedestal fan in India is a straightforward process that involves considering blade size, height, oscillation range, airflow capacity, base diameter, and weight. By understanding these factors, you can make an informed decision and choose the right pedestal fan to keep you cool and comfortable during the hot Indian summers.
