Mount Types: To ensure a proper fit inside the window frame, inside mounted shades will have a deduction of approximately 0.4" based on the window width and 0.25" based on the window height. Inside mounted shades require a minimum frame depth of 2 inches for secure installation. If your window frame depth is less than 2 inches, please select an outside mount.

For outside mounted shades, you should order the exact width of the area you wish to cover. Outside mounts are often used when there is insufficient frame depth for an inside mount. Our shades come with all necessary mounting hardware for both inside and outside mounting.

Inside Mount Measurement: 1. Measure the inside frame width at three locations - the top, middle, and bottom. Record the smallest of the 3 measurements and use that as your inside width when ordering. 2. Measure the height at 3 locations - the left, middle, and right side. Record the smallest of the 3 measurements and use that as your inside height when ordering.

Outside Mount Measurement: 1. Measure the outside frame width, adding 3-6 inches to determine the outside mount width. 2. Measure the outside frame length, adding 4-6 inches to determine the outside mount length. This overlap is recommended to allow appropriate coverage and avoid any light gaps.
