Getting the measurements right is one of the most important steps when installing outdoor blinds. Even small errors can lead to gaps, poor operation, or blinds that simply don’t fit.
Why Accurate Measurements Matters
Outdoor blinds need to fit precisely to:
- Provide proper weather protection
- Prevent gaps and light leakage
- Ensure smooth operation
- Avoid costly adjustments or replacements
Taking the time to measure properly saves time and money later.
Step 1: Decide Inside vs Outside Mount
Before measuring, determine how your blinds will be installed.
Inside Mount (Recess Fit):
- Cleaner, more integrated look
- Requires precise measurements
Outside Mount (Face Fit):
- Installed over the opening
- Better coverage and weather protection
- More forgiving with measurements
Your choice will affect how you measure.
Step 2: Measure the Width
For Inside Mount:
- Measure the width at the top, middle, and bottom
- Use the smallest measurement
For Outside Mount:
- Measure the full width of the opening
- Add extra coverage (typically 50–100mm each side)
- This improves sealing and reduces gaps
Always measure to the nearest millimetre for accuracy.
Step 3: Measure the Height
For Inside Mount:
- Measure from the top of the opening to the bottom
- Take measurements on the left, centre, and right
- Use the smallest measurement
For Outside Mount:
- Measure from where the blind will be mounted to the desired drop point
- Add extra if you want full coverage below the opening
Accurate height ensures proper operation and coverage.
Step 4: Check for Level and Obstructions
Not all openings are perfectly square.
Look For:
- Uneven surfaces
- Sloping floors or ceilings
- Obstructions like lights, beams, or handles
These factors can affect how your outdoor blinds fit and operate.
Step 5: Consider the Track or Mounting System
If you’re installing track-guided blinds:
- Allow space for side channels
- Ensure there’s a solid mounting surface
- Check for clearance around the edges
Different systems may have specific measurement requirements.
Step 6: Double-Check Everything
Before placing an order:
- Re-measure all dimensions
- Confirm measurements are consistent
- Check units (mm vs cm)
Even small mistakes can lead to incorrect sizing.
Common Measuring Mistakes
Avoid these common errors:
- Measuring only once
- Forgetting to account for mounting type
- Not allowing for overlap on outside mounts
- Ignoring uneven surfaces
Careful measuring prevents installation issues.

Final Thoughts
Measuring for outdoor blinds doesn’t have to be complicated, but it does require attention to detail. By choosing the right mount type, measuring multiple points, and accounting for your specific setup, you can ensure a perfect fit.
Getting it right the first time means better performance, improved appearance, and a smoother installation overall.
