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

Decking Area Formula

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

DA = DL * DW
  • Where DA is the Decking Area (ft^2)
  • Dl is the deck length (ft)
  • DW is the deck width (ft) 

To calculate the decking area, multiply the deck length by the deck width.

How to Calculate Decking Area?

The following example problems outline how to calculate Decking Area.

Example Problem #1:

  1. First, determine the deck length (ft0.
    • The deck length (ft) is given as: 10.
  2. Next, determine the deck width (ft).
    • The deck width (ft) is provided as: 10.
  3. Finally, calculate the Decking Area using the equation above: 

DA = DL * DW

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

DA = 10 * 10 = 100.00 (ft^2)

Example Problem #2: 

For this problem, the variables required are provided below:

deck length (ft) = 12

deck width (ft) = 12

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

DA = DL * DW = ?
