How to Measure in Special Situations
(French Doors, Tile Obstructions, Window Cranks, Sliding Doors)
NOTE: All measurements should come from measuring the window.
If you measure your existing blinds, the measurements will be
In the past the most common window treatment for sliding doors
was verticals. You can mount verticals, either within the
door frame, inside mount, or on the wall above the casing, outside
mount. Allow 3-5 inches above the door frame to mount the vertical
brackets. Remember, when measuring the width for an outside mount,
add a minimum of 3-4 inches on both sides of the vertical for
light control. Door handles sometimes protrude and interfere
with the window treatment, be sure to order extension brackets.
These brackets add depth to the headrail, allowing the clearance
for an obstructing door handle. Other window treatments for sliders,
are often cellular or honeycomb type shades and the newest window
covering for sliders, is the Vertiglide. The Vertiglide is measured
like a vertical with similar light protection and clearance guide
These doors are very simple to measure. To assure against light
seepage, measure the width of the glass pane and add as much as
available without interfering with the door locks. Usually you
can go at least 1 or more inches on either side. Ideal would be
2 inches on each side, adding a total of 4 inches to the width.
Allow room for mounting hardware (2" to 6") at
the top. The higher you mount the blind, the greater the clearance,
of the blind off of the window. The length of the blind should
be measured 2-3 inches below the glass. Hold down brackets can
be used to hold the blind in place. Please Note: When you order
a certain width, you are ordering the width of the headrail. The
body (fabric, metal slats, vanes) will always be narrower than
the headrail to allow it to fit inside of the headrail. This discrepancy
is generally not great. However, in the case of roller shades
that are outside mounts, the fabric will be one full inch narrower
than the headrail. You will need to add an inch to your measurement
to get the correct size.
Most blinds are available in 2 on 1 and 3 on 1 headrail.
The benefits of these are that you can open a section of the window
covering and not the entire blind. Depending on the size
of the blind, some products are only warrantied if the blind
is split. This is due to the weight of the blind. This is especially
true with wood and wood composite blinds. Blindsgalore offers
this option on many of the window covering products. Measure
the width of the window and divide it by the number of blinds.
If you require blinds of different widths on one headrail, you
will need to call in the order.
Sometimes because of tile or granite splash or other obstructions,
you may need to have a cut out to allow for the blind to move
freely. Give us the width at the bottom and at the top.
Be clear as to which part needs to be cut out. Specific
diagrams should be submitted for clarification. Cut outs are an
When you are measuring don't forget the cranks. Most often, people
take the cranks off if they interfere with the window covering.
We can order you T-handles, a small wing nut type crank.
Tell us the name of the manufacturer of the window or we can send
you some samples to see which crank fits.
For flush mounts, you need to take into consideration the amount
of widow depth you have to work with. Depending upon the
product, mounting depths vary. Swivel brackets are available for
