Guidelines For A Perfect Fit
- Measure width from left to right, height from top to
bottom, using a steel tape measure. Do not use a cloth tape.
- Depending on your preference and window design, your blinds may be
mounted inside or outside the window casing.
- Measure each window individually, as size variances are common.
- Record width first, then height (also referred to as length) to the nearest 1/8".
Make sure you write the results down.
- Double-check all measurements.
- Do not take your own deductions. The factory will take necessary deductions and
allowances.
Important
Measuring Note:
All roller-style shades with the
RollEase clutch system will have a
fabric reduction of 1/2" on each
side. Therefore, if light control
is critical, outside mount is
recommended.

Horizontal Blinds and Fabric Shades
Inside Mount (IM):
- Inside mount blinds and shades are installed inside the window casing.
Minimum depth requirements vary by product and headrail type, or by tube
size (for roller and solar shades).
- For the width measure the exact distance to the nearest
1/8" between inside surfaces of window frame at the top, middle and
bottom. Use the narrowest width.
- For the height (or length) measure the exact distance to
the nearest 1/8" from inside surface at top of window to sill at the
left, middle and right. Use the longest height. If you prefer
blind not to touch sill, deduct 1/4". If there is no sill,
measure height to point where blind is to reach.
- Measure the window diagonally in two
places, as shown. If the two diagonal dimensions are not equal, we
recommend an outside mount application for optimal function and aesthetics.
-
Do not take any deductions for clearance. (The factory will take necessary deductions for a perfect fit.)
*For
Graber Synergy Products-On inside
mounts, the front shade has a 1/4"
light gap per side, while the back shade
has a 1/2" light gap per
side. For optimal light control,
outside mount is recommended.
Additional Information for Measuring
Bali Roller and Solar Shades:
- On
Continuous Loop inside mounts, there
is a ¾” light gap per side. On
Cordless inside mounts, there is
approximately 1” of light gap on
right and just over ½” on left.
-
For optimal light and glare control,
outside mount is recommended, or you
may add a secondary soft window
treatment (drapery or curtain) to
hide the light gap on an inside
mount.
-
Fabric width is 1-3/8” narrower than
finished shade width of the tube and
its components on Continuous Loop
shades.
-
Fabric width is 1” narrower than
finished shade width of the tube and
components (without valance or side
covers) on Cordless shade
|
Outside Mount (OM):
- Outside mount blinds and shades are installed outside the window casing, covering an area larger than the window itself.
- For the width measure the exact distance to the nearest
1/8" between the outermost points where the blind is to be
placed. For optimum light control, this measurement should extend
3/4" beyond the window opening on each side (or1 1/2" for the
entire width).
- For the height (or length) measure exact distance to the
nearest 1/8" from where top of blind will be located to top of
sill. If there is not sill or if blind is to overlap window frame,
measure to point blind is to reach.
- The factory makes NO allowances on outside mount.

Vertical Blinds
Inside Mount (IB):
- Inside mount blinds are installed inside a window casing or door, or wall to wall in a room.
- For the width measure the opening across the top where
the headrail is to be installed from inside of jamb on left to inside of
jamb on right. Round the measurement down to the nearest
1/8". A minimum depth of 2 7/8" is needed to install
inside the window.
- For the height (length) measure from the inside top of
the opening on the left, at the center and on the right to the sill.
Round the measurement down to the nearest 1/8" and note the smallest
dimension.
- Do not make any allowances. The factory will make
all adjustments so the headrail will fit the opening properly and the
vanes will clear the sill by 1/4" to 1/2".
Inside Mount (IB) Depth Requirements:
- Minimum Depth = 2
7/8"
- Headrail Flush = 3
1/8"
- Channel Valance Flush
= 3 3/4"
- Fabric Flush = 6
3/4"
|
Outside Mount (OB):
- For the width
measure the width of the area to be
covered at the place where the
headrail will be installed to the
nearest 1/8". Blind
should overlap opening at least
4" on each side to ensure
privacy.
- To maximize your
view, allow adequate overlap and
consider the stack width. If you want the entire window uncovered when the blind is fully open, you may need to add more than 6" to the width.
- For the height
measure the height of the area to be
covered and round down to the
nearest 1/8". Blind
should extend at least 3" above
and 3" below opening or window molding.
For ceiling-to-floor installations,
make adequate allowance for
carpeting. Specifying OB
measurement means the factory makes
NO allowances.

|
Caution:
Blinds installed on windows near wall or
baseboard heaters must clear the heaters
by 12" above and 6" to the
side. |
| |
Patio
Doors:
- For the width
measure the width of the area to be
covered at the place where the
headrail will be installed to the
nearest 1/8". Blind
should overlap opening at least
4" on each side to ensure
privacy.
- To ensure easy
access through the door and allow
adequate overlap, consider the stack
width.
- For the height
(length) measure the height of the
area to be covered and round down to
the nearest 1/8". Blind
should extend at least 3" above
opening or window molding.
Deduct 1/2" for proper
clearance. Specifying OB
measurement means the factory makes
NO allowances.

Panel
Tracks/Sliding Panels
Bali Vertical Blinds, VertiCell™ Cellular Shades and Sliding
Panels
- Outside mount blinds are installed outside the window casing,
covering an area larger than the window itself.
- Outside mount is recommended for optimal appearance and
light control.
- Measure the exact width of window, including the frame if there
is one. Add 3" for each side (6" total overlap) to ensure light
control and privacy.
- Measure the exact height of window from top edge of molding to
either: bottom edge of molding; top of sill if there is one; or to
the floor (i.e. to cover a patio door). Add 3" to allow for adequate
mounting area above the window.
- If blind or shade extends to the floor (i.e. to cover a patio
door) you will then need to deduct the following to prevent window
treatment from touching the floor:
- Vertical blinds, VertiCell
shades, sliding panels (roller,
solar and Roman shade fabrics) and
soft vertical blinds - ½"
- Sliding panels (natural shade
fabrics) - 1"
- The factory makes NO allowance on outside mount blinds or
shades.
Graber Sliding Panels
Inside Mount
Inside mount blinds are installed inside the window casing or door,
or wall to wall in a room. For inside mount recess requirements, see
your designer or sales associate.
- 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 top of sill. Record the shortest
measurement.
- Measure the window diagonally in two places as shown. If
the two diagonal dimensions are not equal, we recommend an
outside mount application for optimal shade function and
aesthetics.
- Do not take deductions. Allowances are made at the
factory to ensure a perfect fit.
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 the frame
if there is one. Add 3" for each side (6" total overlap) to
ensure light control and privacy.
- Measure the exact 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 the floor (i.e. to cover patio door)
measure (as in step 2) and add 3" to height to allow for
adequate mounting area above the window and deduct 1/2" for
Roller, Solar and Roman materials for clearance so the
panels do not touch the floor.
- The factory makes NO allowances on outside mount.
