How to measure your wingsuit to determine it's total area in Square Feet

The purpose of this document is to allow wingsuit pilots to relate the size of their suits in a way that they (and other skydivers) are familiar with; Lb/Sq.Ft. wing loading, and denote their performance characteristics, similar to canopies.

Measurement procedures for different sized suits are different. This is merely a guide, use your best judgement.

First ~

Lay your wingsuit out on the floor in front of you, front side to the floor.

Second ~

Find your tape measure. Measure the distances for area A in the diagram below. Length x Width . The areas to measure for square A, are from the edge of the narrowest part of where the armwing and legwing come together. For larger suits, this may not be a factor. L x W in inches.

Third ~

Measure the tailwing, area B. For small suits with less than a flat tail (such as the Swift and Hatch), multiply the total area of the tail by (.4), to account for less tailwing. If your suit appears to have a different amount of tailwing in that area, then account for that in your own equation.

Fourth ~

Measure the the top back area then armwings.

Fifth ~

Add the areas, all figures should be in In. or Square In.

L X W for all areas.

Add all areas together, then take that number and convert sq. inches to Square Ft. -
Take your total Sq. Inches, and multiply by 0.0069, round to nearest number.

That will give you the size of your wingsuit for your measurements in Sq. Ft.

Then take your exit weight of Y, and divide Y lbs / by the Sq. Ft. of your suit to get your Wing Loading. Below is an example for my Aura at my exit weight of 230 lbs, with a wing loading of 10.0 lbs/sq/ft.

A= 44.5in x 46in = 2047 sq.In.
B= 34in x 12in = 408
C= 44.5in x 12in = 534
D= 18in x 9in. = 162
E= 18in x 9in. = 162
A+B+C+D+E= 3313 Sq. Inches. = 23 Sq. Ft.
I weigh 230lbs on exit. 230lbs/23Sq. Ft. = 10Lbs/Sq.Ft.

For Smaller suits, Simply make your best guess of the area of the squares. For intermediate suits, try to use one square, and multiply L x W. For Student Suits, use a box for each wing, and add those areas together. Again, this is a guide, there are better ways to find the area of an object, this is just for ease of use for all involved.
