Wing Taper Ratio Calculator

The “wing taper ratio” is a parameter in aircraft design that describes the ratio of the wing’s tip chord to its root chord. The chord of a wing is the width of the wing from front to back, and the taper ratio indicates how the wing’s width changes from the root (base) to the tip. It’s an important factor that influences the aerodynamic characteristics and performance of the wing.

The formula for calculating the wing taper ratio ($\lambda$) is as follow

  ​​

Where:

• $\lambda$ is the wing taper ratio (dimensionless).
• ct​ is the chord length at the wingtip (typically in meters or feet).
• cr​ is the chord length at the wing root (typically in meters or feet).
