Enter the total room area (ft^2) and the total number of people into the Calculator. The calculator will evaluate the Occupancy Load Factor. 

Occupancy Load Factor Formula



  • OLF is the Occupancy Load Factor (ft^2/person)
  • RA is the total room area (ft^2)
  • AP is the total number of people

To calculate the Occupancy Load Factor, divide the total room area by the number of people.

How to Calculate Occupancy Load Factor?

The following steps outline how to calculate the Occupancy Load Factor.

  1. First, determine the total room area (ft^2). 
  2. Next, determine the total number of people. 
  3. Next, gather the formula from above = OLF = RA / AP.
  4. Finally, calculate the Occupancy Load Factor.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total room area (ft^2) = 400

total number of people = 200
