- Ladder (for reaching upper windows or porch fascia)
- A helper (recommended for precision)
How to Measure for Different Awnings
Awnings Over Windows
Measure the width of the window from outside frame edge to outside frame edge. Add 2–4 inches to each side for better coverage and visual balance. Then measure the desired projection from the wall, this will determine how much shade your awning provides.
Door Awnings
Measure from one side of the door frame to the other, including any trim. Adding a small overhang on each side is recommended to protect the frame and hardware from rain and sun. For the projection, consider how much space you want covered for people entering and exiting.
Back or Front Porch Awnings
Measure the full width of the porch opening, from post to post or wall to wall. Projection is typically greater than for windows or doors, often 4–6 feet or more, to create ample covered space. Be sure to check for obstructions like railings, lights, or hanging plants that might affect placement.
Patio Awnings
For patios, measure the entire length of the area you want covered. Projection can vary significantly depending on whether you want a small shade area or full coverage. It’s important to account for any furniture or grill placement so the awning extends far enough to be functional.
Use the Measurement Reference Table
Wayne Craft’s contractor guide includes a measurement table to make sizing quick and accurate. This table provides recommended awning widths and projections for different types of installations, helping homeowners and contractors select the best dimensions for coverage, appearance, and function.
| TYPE | WIDTH MEASUREMENT | PROJECTION RANGE | NOTES |
|---|---|---|---|
| WINDOW | Frame edge to frame edge + 2—4″ | 2’—4′ | Adds shade and protects glass |
| DOOR | Frame edge to frame edge + slight overhang | 3’—5′ | Protects entryway from rain and sun |
| PORCH | Post to post or wall to wall | 4’—6’+ | Creates sheltered sitting space |
| PATIO | Total length of area to be covered | 4’—8’+ | Covers outdoor seating or dining areas |
Other Important Notes When Measuring
Account for Mounting Height and Obstructions
- Measure from ground level to the mounting point, usually the fascia or wall above the window or door.
- Note nearby obstructions such as gutters, lighting fixtures, or decorative trim.
- These details help awning contractors select the right installation method and hardware.
Consider Style, Ventilation, and Drainage
- Wayne Craft’s aluminum awnings include interlocking seams and drip-edge gutters for efficient rain runoff.
- For porch awnings with high foot traffic, maintain enough slope for proper drainage.
- Ventilation helps reduce heat buildup, consider side vents or styles with built-in airflow.
Specify Custom Features
Wayne Craft offers multiple customization options for aluminum awnings:
- Valances (single or double) or a clean, valance-free look
- Slope styles such as convex or straight
- Decorative accents like sunburst designs or header bars
These features may slightly influence sizing and overall appearance.
Double-Check and Record

- Record:
