Horizontal Blinds and Fabric Shades
Outside
mount:
Outside mount blinds
and shades are installed outside the window casing, covering an area
larger than the window itself.
Measure the exact
width to be covered. Be sure the measurement overlaps the window opening
by at least 1-1/2" on each side (3" total overlap) to ensure
light control and privacy.
Measure exact height
to be covered, including desired overlap (typically from top edge of
molding to bottom edge, or to top of sill if there is one).
The factory makes NO
allowances on outside mount.
Outside mounts are more attractive if a
valance with Returns is used. Many of our valances offer Returns
The Standard inside length of the returns are 2 1/2". If you prefer a
longer or shorter Return, we will gladly customize the Return for you. Please

will help you with Special Requests.
Vertical Blinds
Inside mount:
Inside mount blinds
are installed inside a window casing or door, or wall to wall in a room.
The window casing must be at least 2-3/4" deep for track flush
mount or 3-3/4" deep for louvers flush mount. Otherwise, an angle
bracket may be necessary.
Measure the exact
inside width of window casing from one inside edge to the other in three
different places. Record the narrowest measurement.
Measure the exact
height in three different places from top edge of opening to bottom, or
top edge of sill if there is one. Record the shortest measurement.
Do not take any
deductions for clearance. The factory will take necessary deductions for
a perfect fit.
Vertical Blinds
Outside mount:
Outside mount blinds
are installed outside the window casing, covering an area larger than
the window itself.
Measure the exact
width of window, including frame if there is one. Add 3" for each
side (6" total overlap) to ensure light control and privacy.
Measure height of
window from top edge of molding to bottom edge, or to top of sill if
there is one. Add 3" to allow for adequate mounting area above the
window.
If blind extends to
floor (i.e., to cover patio door), measure height in three places, take
the smallest measurement and deduct at least 1/2" for clearance so
the louvers don't touch the floor.
The factory makes NO
allowances on outside mount.

Measuring for Shutters
Before you begin measuring, choose whether the shutter will be mounted inside the window opening (IM) or outside the window opening (OM).
Inside mount shutters attach and hang inside the window opening for a flush, clean look that highlights decorative window trim. Outside mount shutters hang outside the window opening, either on the window trim or above and beyond the window frame. Outside mounting can make a window appear larger, or hide an unattractive window. To maintain a tilt and clean feature on your windows you may need to use an outside mount.
If the diagonal measurements inside your window opening vary by more than Ό we strongly suggest an outside mount (see illustration to left).
Outside Mount
Windows without Molding or Trim
(Installation on Wall)
First measure the width of the window opening in three places top, middle, and bottom. Add 2 inches to the widest measurement and order this width. Next, measure the height of the window opening in three places left center and right. Add 2 inches to the tallest measurement and order this height.
NOTE: You must add 2 to both width and height to allow for the shutter frame.
Outside Mount
Windows with Molding
(Installation on Trim or Molding)
First measure the width of the window molding in three places top, middle, and bottom. Order the widest measurement. Next, measure the height of the window trim in three places left, center and right. Order the tallest measurement.
The size ordered for this mounting option will include the shutter frame. (Please note that the installation is easier if the window molding is at least
1 1/8 wide.)
Outside Mount
Window with Molding
(Installation Surrounding or Beyond Molding)
First, measure the width of the outer edge of the molding in three places top, middle and bottom; add 2 1/4 to the widest width. Order this width.
Next, measure the height of the outer edge of the molding at three places right, center and left; add 2 1/4 to the tallest height. Order this height.
NOTE: You must add 2 1/4 to both the largest width and height so the shutter frame will clear the molding on all sides.
Inside Mount
(Installation Inside Window Opening)
First measure the width of the window opening in three places top, middle, and bottom. Order the narrowest or smallest measurement. Next, measure the height of the window opening in three places left, center and right. Order the shortest measurement.
NOTE: A minimum window depth of 2 is needed for an inside mount to be installed flush with the surrounding wall or trim. This depth is not necessary if the shutter is to protrude slightly out from the window opening. The factory will take the appropriate deduction in width and height. DO NOT MAKE ANY DEDCUTIONS or ALLOWANCES.
More Measuring Tips
Always use a metal tape measure for accuracy and record measurements to the nearest 1/8 of an inch.
Please do not take any allowances: the factory will make all necessary deductions.
Always measure each window you plan to cover. Windows of different sizes can appear deceptively similar.
