Use and Care Manual
For inside mounts:  
Record the 
narrowest width and 
longest height.
For outside 
mounts: Add extra 
inches (approximately 
3") to the width and 
height for optimum 
light control and 
privacy.
For inside mounts:  
Record the 
narrowest width and 
shortest height.
For outside 
mounts: Add extra 
inches to the width 
(3-6") for optimum 
light control and 
privacy, or if you want 
the entire window 
uncovered when the 
blind is fully open. To 
ensure vanes clear 
the floor, deduct 
1/2" from the height 
measurement.
For all measurements, use a steel tape measure only. 
Measure to the nearest 1/8". 
HOW TO MEASURE WINDOW TREATMENTS
Inside Mount 
window treatments 
are installed inside 
the window casing.
Outside Mount 
window treatments 
are mounted outside 
the window casing 
and provide better 
privacy. Mount directly 
on the wall or to the 
window molding.
For inside mounts: 
Measure the inside 
of the window frame 
in 3 places for width 
and height.
For outside 
mounts: 
Measure the 
overall area to 
be covered.
