Enter the area of the room (ft^2) and the occupancy index (ft^2/person) into the Calculator. The calculator will evaluate the Max Occupancy. 

Max Occupancy Formula

MO = A / UA

Variables:

  • MO is the Max Occupancy (people)
  • A is the area of the room (ft^2)
  • UA is the occupancy index (ft^2/person)

To calculate Max Occupancy, divide the area of the room by the occupancy index.

How to Calculate Max Occupancy?

The following steps outline how to calculate the Max Occupancy.


  1. First, determine the area of the room (ft^2). 
  2. Next, determine the occupancy index (ft^2/person). 
  3. Next, gather the formula from above = MO = A / UA.
  4. Finally, calculate the Max Occupancy.
  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.

area of the room (ft^2) = 1,000

occupancy index (ft^2/person) = 20

Frequently Asked Questions (FAQ)

What is an occupancy index and how is it determined?

The occupancy index is a measure of the amount of space allocated per person within a room or building, usually measured in square feet per person. It is determined based on building codes, safety regulations, and the intended use of the space.

Why is it important to calculate Max Occupancy?

Calculating Max Occupancy is crucial for ensuring safety and comfort within a space. It helps prevent overcrowding, ensures compliance with legal and safety standards, and optimizes the use of space.

Can the occupancy index vary between different types of spaces?

Yes, the occupancy index can vary significantly between different types of spaces, such as offices, classrooms, and public venues, due to differing safety requirements, the nature of activities conducted, and the layout of the space.

How can changes in room layout affect Max Occupancy calculations?

Changes in room layout, such as the addition of furniture or equipment, can impact the available space per person, thereby affecting the Max Occupancy calculation by either increasing or decreasing the occupancy index.
