Enter the lawn length (ft) and the lawn width (ft) into the Lawn Area Calculator. The calculator will evaluate the Lawn Area. 

Lawn Area Formula

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

LA = LL * LW / 43,560
  • Where LA is the Lawn Area (acres)
  • LL is the lawn length (ft) 
  • LW is the lawn width (ft) 

To calculate the lawn rea, multiply the lawn length by width in feet, then divide by 43,560.

How to Calculate Lawn Area?

The following example problems outline how to calculate Lawn Area.

Example Problem #1:

  1. First, determine the lawn length (ft).
    • The lawn length (ft) is given as: 300.
  2. Next, determine the lawn width (ft).
    • The lawn width (ft) is provided as: 600.
  3. Finally, calculate the Lawn Area using the equation above: 

LA = LL * LW / 43,560

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

LA = 300 * 600 / 43,560 = 4.132 (acres)


Example Problem #2: 

For this problem, the variables required are provided below:

lawn length (ft) = 1000

lawn width (ft) = 2000

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

LA = LL * LW / 43,560 = ?
