Here are some useful ceiling fan calculators that I have created over the past several years that are being used in various places on our website.
I thought it might be a good idea to consolidate them all on a single page.
Ceiling Fan Size Recommendation Calculator
This calculator is based on the current trend to use Larger fans in Smaller rooms. Based on this new trend, we recommend this: "Choose the largest fan with the highest wind speed that will fit into the space without overwhelming it visually". In rooms larger than 10 x 10, leave 2 to 3 feet from the blades to the shortest wall to determine the largest size we would recommend visually.
Select the dimensions of your room (round to nearest foot)!
Enter the overall blade span of any fan and click calculate to determine the maximum RPM that any size fan can operate.
Details: Federal regulations limit the maximum RPM at which a ceiling fan safely operate in order to prevent potential bodily harm. The limitations are based on the above 2 blade thicknesses. Blades that are 1/8" thick and less than 3/8" thick must run slower than blades that are 3/8" thick or more. No residential ceiling fans are allowed to have blades less than 1/8" thick. Any ceiling fan that does not meet the maximum RPM requirement cannot be installed less than 10 feet from the floor, or must be enclosed in a cage.
CFM Missing Value Calculator
Use this to find a missing value when you only know 2 of the values. So basically, enter 2 values to calculate the missing value. What is the use for this? Suppose the manufacturer publishes the CFM on High and the CFM Weighted Average (Energy Guide CFM). You can use this to find the CFM on Low speed so you can get a true range of the fans performance.
