The mounting brackets sit outside or on top of the window frame. With this mount, the shade or blind covers the window frame as well as the window. The outside mount is often chosen to hide an unattractive window or create the illusion of a larger window.
- Measure the width across the window for the area that you want the blind to cover. You can typically add 2 to 4 inches (1 to 2 inches on each side) to the actual width of the window to ensure that the sunlight doesn't peak through the ends. However, be aware that an excessive window treatment width can appear overly large when the shade is raised and the window frame beneath can be seen. Record this measurement.
- Measure the height of the area where you want the blind to cover. The height you record should include the headrail and valance. Record this measurement.
- The factory will not take any deductions from your measurements for an outside mount. Deductions are only taken for inside mounts. Your window treatment will arrive with the exact measurements you provide for an outside mount.
- Double check your measurements! There are no refunds or returns based on incorrectly measured, recorded or conveyed measurements.
