Enter the total building footprint (ft^2) and the total lot area (ft^2) into the Coverage Area Calculator. The calculator will evaluate the Coverage Area. 

Coverage Area Formula

The following two example problems outline the steps and information needed to calculate the Coverage Area.

CA = F/LA * 100
  • Where CA is the Coverage Area (%)
  • F is the total building footprint (ft^2) 
  • LA is the total lot area (ft^2) 

To calculate the coverage area, divide the total building footprint by the total lot area.

How to Calculate Coverage Area?

The following example problems outline how to calculate Coverage Area.

Example Problem #1:

  1. First, determine the total building footprint (ft^2).
    • The total building footprint (ft^2) is given as: 1000.
  2. Next, determine the total lot area (ft^2).
    • The total lot area (ft^2) is provided as: 2000.
  3. Finally, calculate the Coverage Area using the equation above: 

CA = F/LA * 100

The values provided above are inserted into the equation below and computed.

CA = 1000/2000 * 100 = 50.00 (%)

Example Problem #2: 

For this problem, the variables required are provided below:

total building footprint (ft^2) = 1500

total lot area (ft^2) = 3500

Test your knowledge using the equation and check your answer with the calculator..

CA = F/LA * 100 = ?
