From where to where is the chord of a wing measured?

The chord of a wing is defined as the straight line distance between the leading edge and the trailing edge. This measurement is critical in aerodynamics since it helps determine the wing's performance characteristics, such as lift and drag. The chord line also provides a reference for calculating various parameters related to the shape and area of the wing, which influence how the aircraft behaves in flight.

Measuring from the leading edge to the trailing edge allows for a consistent framework for wing design, analysis, and performance evaluation. Understanding the chord length is essential for aerodynamic calculations and optimizing the wing's efficiency, including how it affects airflow and stall characteristics.
