Window Blinds Measuring Instructions

You can mount your window blinds or window shades inside the window frame/casing or outside mounted to the wall above the window.

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 to "flush mount" your blinds, do not select a cornice style valance.

Inside Mount Window Blinds and Window Shades When mounting blinds inside the window casing or frame. Simply measure the width and length in three different places as shown in the inside mount picture. i.e. inside drywall to drywall or frame to frame. It is only necessary to give the smallest length and width to an 1/8 of an inch. Enter exactly what your window frame measures. Take NO deductions. Ensure you have enough window depth. See individual products for details. The factory will take proper deductions to fit the size window you specify.

Outside Mount Window Blinds and Shades When mounting blinds outside the window casing. Simply measure the width and length of the window in three places Remember it is only necessary to give the measurement to an 1/8 of an inch. Horizontal Blinds Add 3 inches to the width and length measurement. Vertical Blinds Add 4 inches to the width and 3" length measurement. The factory will take NO deductions on outside mount blinds or shades. You MUST add for overlaps.
