Sizing and Installation
Most awning disappointments start at the tape measure: a unit that is too narrow to shade the table, a pitch too shallow to shed rain, or a front bar that clips a door or a tall guest's head. These guides cover the measurements, geometry, fasteners and approvals that decide whether an installation works for years or pulls out of the wall.
How to Measure for an Awning (Patio, Window, Door and RV)
Measure the clear wall width you can mount on, the depth of the area you want shaded, and the height from the ground to the highest solid mounting point. Then subtract the awning's drop at your chosen pitch from that height and confirm at least 80 inches (6 ft 8 in) of headroom remains at the front bar.
