Awning Mounting Height Calculations for 10° and 20° Slopes

8'2" awning, factory-set 10° slope. Needs front edge at 90" height. What mounting height at house? Also for adjustable 20° slope.

Calculated Mounting Heights

10° slope: Fall = 1'5". Mounting height = 90" + 17" = 8'11". Overall length foreshortens to 8'0.5".
20° slope: Fall = 2'9.5". Mounting height = 10'3.5". Foreshortens to 7'8.06".

Method

Simple trigonometry. Expert used AutoCAD for precision. Measurements from house connection point to awning tip. Mounting beam offset would slightly alter numbers.
