4. Installation Guide
4.1 Measuring Your Window
Accurate measurements are crucial for proper fit and function. Determine whether you will use an inside mount or outside mount.

Image: Visual guide for measuring windows for both inside and outside mount installations. For inside mount, measure the minimum window size and ensure window depth is at least 1.5 inches. For outside mount, measure the maximum window size and add 4 inches to the width.

Image: Detailed instructions on how to measure for inside and outside mount blinds, including considerations for window depth and adding extra width for outside mounts.
For Inside Mount: The window frame depth must be at least 1.5 inches. If your chosen blind width is 34 inches, the no-drill mechanism adds 0.5 inches, making it suitable for window frames between 34 and 34.5 inches wide. Order width = window width - 0.25 inches.
For Outside Mount: Order width = window width + 4 inches. The adjustable height range of shades is 0-72 inches.
4.2 No-Drill Installation Steps
- Place the end of the blind with the no-drill device to the left side of the window frame.
- If there is a gap between the top rail and the window frame, use a silicone pad to stick to the right side of the top rail, then push the right side of the smart blind into place.
- After installation, ensure to fasten the non-drill device securely.
