Selecting an appropriately sized lateral arm awning starts with accurate site measurements. For both manual and motorized retractable awnings, proper sizing is essential for reliable operation and long-term durability.
With the right width, projection, and mounting height, lateral arm retractable awnings can be installed to meet both functional and architectural requirements.
Key Measurement Points
Start by identifying the total width of the patio or wall area where the awning will be installed. The vertical clearance and space for the arms to extend also need to be accounted for.
- Measure the total wall width where the awning will be mounted.
- Note any obstructions such as windows, lights, or vents.
- Measure the vertical space above doors or windows for mounting brackets.
- Confirm the direction the wall faces (south and west-facing walls receive the most sun).
- Observe how the sun moves across the space during different times of the day to identify when shade is needed most.
Double-check all dimensions to avoid misalignments that could affect installation or performance.
Mounting Location and Clearance Needs
Awning performance depends on its mounting height and angle. Most retractable awnings in Canada must be high enough to allow full projection without hitting nearby obstacles.
- Check for at least 8 feet of vertical space for full projection and head clearance.
- Choose a wall, soffit, or roof mount based on the patio layout and structure.
- Confirm a clear space in front of the wall to allow arms to extend fully.
These adjustments will allow the awning to operate smoothly and avoid contact with railings, trees, or overhangs.
Common Sizing Errors
Rushing through measurements can lead to gaps in shade or poor fit. Some of the most common mistakes include misjudging slope angles or underestimating how far the awning needs to be projected.
- Confusing projection with width; both are measured differently.
- Forgetting to measure slopes or height differences across the patio.
- Ignoring gutter downspouts, outdoor lighting, or corner brackets.
Understanding these issues helps avoid installation delays and costly corrections.
Projection Vs. Width
The projection refers to the distance the awning extends outward from the mounting point, while the width represents the horizontal span across the wall. Choosing the correct projection guarantees full coverage of the seating or dining area.
- Standard projections range from 6.5 to 13 feet.
- Widths can be customized to fit the space or design vision.
- Motorized models may offer pitch adjustment features to fine-tune sun coverage.
- Consider whether a drop valance or adjustable shade is needed for extra sun control.
Understanding the balance between width and projection is key to creating a functional shade footprint.
Consultation Benefits in Canada
While measuring may seem straightforward, local weather and building codes can influence the choice of a retractable awning.
- Discuss weather concerns, such as snow loads or wind zones.
- Receive recommendations on fabric types, controls, or frame materials.
- Learn about installation best practices specific to the region.
- Review mounting bracket options if the clearance height is limited.
A consultation also makes sure that the motorized retractable awnings comply with local zoning requirements and deliver consistent performance.
