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 = RA / AP

Variables:

  • 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

Frequently Asked Questions

What factors can affect the Occupancy Load Factor?

The Occupancy Load Factor can be affected by several factors including the layout of the room, the presence of furniture or equipment, and regulations set by local building codes.

How can the Occupancy Load Factor be used in planning events?

Event planners can use the Occupancy Load Factor to determine the maximum number of guests that can safely and comfortably fit in a venue, ensuring compliance with safety standards and enhancing the overall guest experience.

Are there different Occupancy Load Factors for different types of buildings?

Yes, different types of buildings such as offices, restaurants, and theaters may have different standards for calculating Occupancy Load Factors, often based on the specific use and layout of the space.

Can the Occupancy Load Factor change over time?

Yes, the Occupancy Load Factor can change if modifications are made to the room or building, such as renovations or changes in furniture layout, which can alter the available space or the way people move through it.
