Calculating Wing Area

Calculating the Wing Area for Constant Chord Wings

Constant chord wings are simple, it is found by multiplying the width x the length.  In aircraft terms that is:

Wing Area = Wing Span x Wing Chord

Calculating the Wing Area for Tapered Wings

To find the area of a tapered wing, use the formula for a Trapezoid.  Find the average chord and multiply it times the wing span:

Average Chord = ( Root Chord + Tip Chord ) ÷ 2

Wing Area = Wing Span x Average Chord

If the wing has multiple tapers then calculate each trapezoidal area and add them together.

Calculating the Wing Area for Delta Wings

If a Delta Wing has a Tip Chord greater than 0 inches, then use the formula for a tapered wing as above.

If the Tip Chord is 0" then use the formula for a triangle:

Wing Area = 1/2 x Wing Span x Root Chord
