Guide for measurement
Step 1: Measuring the window niche depth
Before you measure the width and height of your window, it is important to check the recess depth to ensure there is enough space for the covering to fit.
- Minimum niche depth required: 3 centimeters for correct installation.
- Here's how to measure: Start at the front edge of the window niche (the part that is farthest from the window) and measure to the shallowest point within the niche.
Watch out for obstacles
Common obstacles in your window niche include:
- Window handle
- Lock bracket
- Locking mechanisms
- Cranks or crank mechanisms
Measurement with obstacles
Even if your window niche is deep, obstacles can prevent the blinds from closing properly. To ensure everything fits:
- Measure the niche depth from the front edge of the niche to the window.
- Measure the obstacle depth from the front of the window to the front edge of the obstacle (e.g. a handle).
- Subtract the obstacle depth from the niche depth to obtain your unobstructed space.
Important: You need at least 3 centimeters of unobstructed space to be able to install the blind safely.
Step 2: Measuring the width
Since windows are often not perfectly square, you need to measure the width at three different places to account for any irregularities:
- At the top of the window niche
- Middle of the window niche
- At the bottom of the window niche
Note the smallest of these three measurements. This ensures that your blind fits even at the narrowest point of the window.
Step 3: Measuring the height
Then measure the height of your window niche. Again, take measurements from three different places:
- Left side of the window niche
- Middle of the window niche
- Right side of the window niche
Just like with the width, note the smallest of these three measurements.
Avoid common measurement errors
To get the most accurate measurements, avoid these common mistakes:
- Measurement at an angle: Always keep the measuring tape straight and level.
- Bendable measuring tape: Make sure the measuring tape is taut to get accurate measurements.
- Incorrect rounding: If necessary, round to the nearest millimeter.

Step 1: Measuring the window's niche depth
Before you measure the width and height of your window, it is important to check the recess depth to ensure there is enough space for the covering to fit.
- Minimum recess depth required: 3 centimeters for proper installation.
- How to measure: Start at the front edge of the window recess (the part that is farthest from the window) and measure to the shallowest point within the recess.

Watch out for obstacles
Common obstacles in your window niche include:
- Window handles
- Lock fittings
- Lock mechanisms
- Cranks or crank mechanisms

Even if your window niche is deep, obstacles can prevent the blinds from closing properly. To ensure everything fits:
- Measure the niche depth from the front edge of the niche to the window.
- Measure the obstacle depth from the front of the window to the front edge of the obstacle (e.g., a handle).
- Subtract the obstacle depth from the niche depth to determine your unobstructed space.
Important: You need at least 3 centimeters of unobstructed space to install the Guard safely.

Step 2: Measuring the width
Since windows are often not perfectly square, you need to measure the width at three different points to account for any irregularities:
- At the top of the window recess
- In the middle of the window recess
- At the bottom of the window recess
Note the smallest of these three measurements. This ensures that your Guard fits even at the narrowest point of the window.

Then measure the height of your window niche. Again, take measurements from three different places:

Avoid common measurement errors
To get the most accurate measurements, avoid these common mistakes:
- Measuring at an angle: Always keep the measuring tape straight and level.
- Bent measuring tape: Make sure the measuring tape is taut to get accurate measurements.
- Incorrect rounding: If necessary, round to the nearest millimeter.
