Enter the total wingspan (ft) and the total wing area (ft^2) into the Wing Aspect Ratio Calculator. The calculator will evaluate the Wing Aspect Ratio. 

Wing Aspect Ratio Formula

The following two example problems outline the steps and information needed to calculate the Wing Aspect Ratio.

WAR = WS^2 / A


  • WAR is the Wing Aspect Ratio ( )
  • WS is the total wingspan (ft) 
  • A is the total wing area (ft^2) 

To calculate the wing aspect ratio, square the total wingspan, then divide by the total wing area.

How to Calculate Wing Aspect Ratio?

The following steps outline how to calculate the Wing Aspect Ratio.

  1. First, determine the total wingspan (ft). 
  2. Next, determine the total wing area (ft^2). 
  3. Next, gather the formula from above = WAR = WS^2 / A.
  4. Finally, calculate the Wing Aspect Ratio.
  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.

total wingspan (ft) = 30

total wing area (ft^2) = 250

WAR = WS^2 / A = ?
