Dimensions Guide

1. To find width: Measure exact distance to the
nearest 1/8" between the outermost points
where the blind is to be placed. For optimal
light control, this measurement should extend
3/4" beyond the window opening on each side
(or 1 1/2" for the entire width).
2. To find height: Measure exact distance to
the nearest 1/8" from where top of the blind
will be located to the top of sill. If there is no
sill or if blind is to overlap window frame,
measure to the point the shade reaches.
allow some overlap
For outside mount applications allow the
blind to overlap 1 1/2" to 3" on the sides, top
and bottom of the window.
You must add the overlap to your
measurement; Levolor does not add width or
height for overlap on Outside Mounted
blinds.
