Step 1: Measuring Your Window’s Recess Depth

Before you measure the width and height of your window, it’s important to check the recess depth to ensure there’s enough space for the Guard to fit inside.

• Minimum recess depth required: 1.3 inches (3.3 cm) for proper installation.
• How to measure: Start at the front edge of the window recess (the part farthest from the window) and measure to the shallowest point within the recess.

Measuring with Obstructions

Even if your window recess is deep, obstructions can prevent the blinds from closing properly. To ensure everything fits:

• Measure the recess depth from the front of the recess to the window.
• Measure the obstruction depth from the front of the window to the front of the obstruction (e.g., a handle).
• Subtract the obstruction depth from the recess depth to find your unobstructed recess space.

Important: You need at least 1.3 inches (3.3 cm) of unobstructed recess space to install Guard securely.

Step 2: Measuring the Width

Since windows are often not perfectly square, you need to measure the width in three different places to account for any unevenness:

• Top of the window recess
• Middle of the window recess
• Bottom of the window recess

Record the smallest of these three measurements. This ensures your Guard fits the narrowest point of your window.

Step 3: Measuring the Height

Next, measure the height of your window recess. Once again take measurements from three locations:

• Left of the window recess
• Middle of the window recess
• Right of the window recess

Just like with the width, record the smallest of these three measurements.

Avoid Common Measuring Mistakes

To get the most accurate measurements, avoid these common errors:

• Measuring at an angle: Always hold the tape measure straight and level.
• Bending the tape measure: Keep the tape straight to ensure accurate measurements.
• Rounding incorrectly: Round to the nearest sixteenth of an inch (tenth of a centimeter) if needed.
