G’day! Ready to add some shade and style to your home? Proper measurement is the cornerstone of successful awning installation. As someone who’s helped countless Aussie homeowners transform their outdoor spaces, I’ll guide you through the exact steps to measure your windows for awnings – no drama, just straight-up practical advice.
Understanding Awning Measurements
Before we dive in with the measuring tape, let’s get our heads around what we’re actually measuring. Think of awning measurements like tailoring a suit – get it right, and it’ll look schmick; get it wrong, and well… you’ll be back to square one.
“The most common mistake I see is people rushing their measurements,” says James O’Connor, a veteran awning installer from Sydney. “Take your time, measure twice, and you’ll only have to buy once.”
Key Measurement Components
- Window width
- Window height
- Projection (how far the awning extends)
- Mounting height
- Side clearances
Essential Tools for Measuring
Having the right tools on hand is like having the right ingredients for a barbie – essential for success.
You’ll need:
- Metal measuring tape (at least 5 metres long)
- Spirit level
- Pencil and paper
- Ladder (if required)
- Helper (recommended)
- Camera or smartphone for photos
“Digital measurements are good, but always back them up with manual measurements. Technology can fail, but a good old measuring tape rarely lets you down.” – Sarah Chen, Melbourne Awning Specialist
Step-by-Step Measurement Guide
Let’s roll up our sleeves and get stuck into the actual measuring process.
1. Measuring Window Width
First things first – the width measurement is your foundation. Here’s how to nail it:
- Measure the entire window width from trim to trim
- Add 100mm to each side (200mm total) for optimal coverage
- Record both measurements (actual and recommended)
2. Determining Mounting Height
The mounting height can make or break your awning’s effectiveness.
- Measure from the bottom of where the awning will mount to the ground
- Consider any obstacles (lights, pipes, etc.)
- Factor in the minimum height requirements for your area
“Always consider your climate when deciding on mounting height. In areas like Queensland where tropical downpours are common, you might want to increase the pitch angle, which affects your required mounting height.” – Mike Peterson, Brisbane Awning Designer
3. Calculating Projection
The projection is how far your awning will extend from your wall – crucial for getting the right amount of shade.
Standard projection guidelines:
- Small windows (up to 1.5m): 700mm-1000mm
- Medium windows (1.5m-2.5m): 1000mm-1500mm
- Large windows (2.5m+): 1500mm-2000mm
Special Considerations for Different Window Types
Not all windows are created equal, mate. Let’s look at the special requirements for different types.
Bay Windows
For bay windows, you’ll need to:
- Measure each section separately
- Account for angles
- Consider multiple smaller awnings instead of one large one
French Doors
When measuring for French doors:
- Include the entire door frame
- Account for door swing
- Consider handle clearance
Corner Windows
Corner windows require extra attention:
- Measure each window separately
- Account for corner overlap
- Consider corner bracket requirements
Common Measurement Mistakes to Avoid
Learn from others’ mishaps to ensure your project goes smoothly.
The Big Don’ts
- Forgetting about obstacles
- Not accounting for window operation
- Ignoring building regulations
- Skipping the double-check
- Not considering sun angles
Choosing the Right Awning Size
Size matters when it comes to awnings. Here’s how to choose wisely.
Coverage Recommendations
- Minimum overhang: 100mm each side
- Standard projection ratio: 65-75% of window height
- Maximum width: Usually 7 metres (check manufacturer specs)
Professional Tips and Tricks
After years in the business, here are some golden nuggets of wisdom.
- Consider seasonal sun angles
- Account for future maintenance
- Think about automation clearance
- Factor in wind resistance
- Plan for water runoff
Local Building Regulations
Before you get too excited, let’s talk about keeping things above board.
Council Requirements
Different councils have different requirements. Generally, you’ll need to consider:
- Heritage overlays
- Maximum projection allowances
- Height restrictions
- Neighbour considerations
Industry Standards
Make sure your measurements comply with:
- AS 4284 – Testing of Building Facades
- AS 1170.2 – Wind Actions
- BCA Section 3.6 – Glass Installations
Conclusion
Measuring for awnings might seem like a complex task, but with the right approach, it’s absolutely achievable for any homeowner. Remember, precise measurements are your ticket to a perfect fit and years of satisfaction with your new awnings. Take your time, double-check everything, and don’t hesitate to seek professional advice if you’re unsure.

Frequently Asked Questions
Q: How high should I mount my awning?
A: Generally, mount your awning at least 2.4m from the ground to comply with most Australian building codes.
Q: Do I need council approval for awnings?
A: It depends on your location and awning size. Check with your local council for specific requirements.
Q: What’s the minimum clearance needed around a window for an awning?
A: Allow at least 100mm clearance on each side of the window and 200mm above for proper installation.
Q: Can I measure for awnings by myself?
A: While possible, it’s recommended to have a helper for accuracy and safety, especially for larger windows.
Q: How do I measure for retractable awnings?
A: Follow the same basic principles but also consider the cassette size and full extension measurements.
Q: What’s the standard projection for an awning?
A: Typically 65-75% of the window height, but this can vary based on your specific needs and local climate.
Q: How do I measure for corner windows?
A: Measure each window separately and consider using corner brackets or multiple awnings depending on the configuration.
Q: Will heavy rain affect my awning measurements?
A: Yes, consider a steeper pitch angle in areas with heavy rainfall, which may affect your mounting height calculations.
