Enter the window length (in) and the window height (in) into the Window Area Calculator. The calculator will evaluate the Window Area. 

Window Area Formula

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

WA = WL /12 * WH/12

Variables:

  • WA is the Window Area (ft^2)
  • WL is the window length (in) 
  • WH is the window height (in) 

To calculate wind area, multiply the window length by the window height, then convert to the correct units if necessary.

How to Calculate Window Area?

The following steps outline how to calculate the Window Area.

  1. First, determine the window length (in). 
  2. Next, determine the window height (in). 
  3. Next, gather the formula from above = WA = WL /12 * WH/12.
  4. Finally, calculate the Window Area.
  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.

window length (in) = 25

window height (in) = 36

WA = WL /12 * WH/12 = ?
