Window Blinds Measuring Instructions

Measure Window Blinds Top View You can mount your window blinds or window shades inside the window frame/casing or outside mounted to the wall above the window. If you are mounting the blinds with an enclosed area such as between two cabinets, follow the inside mount instructions.

In order to mount the window blinds or window shades inside a window casing, make sure you have enough depth to allow room for the window blinds(See figure to the right). Specifications for window blinds or window shades are given on the minimum depths to mount them.

Note: If your window frame depth is not deep enough for a "flush mount" and you need returns on your valance to cover the visible portion of the headrail, please call us and speak to one of our customer service agents prior to ordering.
