Wingload for Skydiving vs AltiX Skydiving

A simple wing load calculator for skydiving. Wing loading is a measurement of how much total weight is supported by how large a wing, and is expressed in pounds per square foot. This tool lets you calculate your wing load using both metric and imperial units. You can also compare your wing loading on different sizes of canopies using the compare feature.
