How to use this calculator
- Select the calculation mode and preferred measurement units.
- Enter the opening, mounting, projection, length, and angle values.
- Choose manual solar angles or automatic location-based solar calculations.
- Add installation, wind, bracket, clearance, and manufacturer limits.
- Enter optional material, motor, installation, electrical, and tax costs.
- Press the calculate button and review results above the form.
- Check every warning before ordering materials or approving installation.
Measure from finished surfaces. Use manufacturer drawings for final bracket positions and arm clearances.
Measurement and installation guidance
| Item | How to measure | Planning note |
|---|---|---|
| Opening width | Measure the full area needing shade. | Add side coverage where low-angle sunlight is important. |
| Mounting height | Measure vertically from finished floor or ground. | Confirm the supporting structure at bracket locations. |
| Projection | Measure horizontally from wall to front bar. | Do not confuse projection with sloped fabric length. |
| Angle | Measure downward from a horizontal reference. | A greater angle increases drop and reduces projection. |
| Clearance | Measure under the lowest valance point. | Allow for fabric movement and uneven ground. |
Frequently asked questions
What is awning projection?
Projection is the horizontal distance from the mounting wall to the awning front edge.
Is projection the same as awning length?
No. Length follows the sloped awning surface, while projection is horizontal.
How does angle affect projection?
Increasing the downward angle creates more drop and less horizontal projection for the same length.
What angle should an awning use?
The correct angle depends on drainage, clearance, sun position, and manufacturer instructions.
Can this calculator size structural anchors?
No. It provides screening loads only. Anchor design requires verified construction details and local code checks.
How accurate are automatic solar angles?
They are suitable for planning but can differ slightly from specialized solar design software.
Why can the sun be behind the facade?
Facade orientation and solar azimuth determine whether direct sunlight reaches that wall.
Should retractable awnings remain open in wind?
Usually not during strong winds. Follow the specific wind class and retraction guidance.
Does the cost estimate include every project expense?
No. Permits, access equipment, repairs, custom fabrication, and regional labor differences may add costs.
