step 3

Select a mount option:

Learn more about mount

Mount refers to whether the treatment will be mounted within the window frame (inside mount) or on the wall surrounding the window (outside mount).

For an inside mount, please provide us with the exact dimensions of the window frame.  Any deductions to the size of your shade will be made by the manufacturer.

For an outside mount, please enter the width and height of the window-covering itself.  We recommend adding at least 4 inches to the width of the window, and 4 inches to the height of the window.  This will allow for proper overlap with the wall.




Inside mount blinds will fit within the window casing for a clean, custom look.  Enter the actual size of your window casing, NOT the size of your old blind.  We will make the necessary deductions to make the blind fit properly.  Make sure your window meets the minimum inside mount specifications, or flush mount specifications if desired.


Outside mount blinds will be installed on the wall above the window, covering the window entirely.  Enter the size you want the finished product to be, including the desired overlap beyond the window.  The ordered height will include the hardware for blinds and shades.  The width of the headrail may be slightly wider than the ordered width to accomodate operating controls and valance returns.  The outside mount option is required if your window is not deep enough to install the blind as an inside mount.

step 5

Select an arch position option:

Learn more about arch position

When making your shade, the manufacturer can include the proper brackets to mount your shade within an arch (standalone) or as part of a palladium window where a rectangular shade will be mounted below the arched shade (arch over standard).

Stand-Alone Arch

Stand-Alone Arch


Choose this option when the window has a rectangular section on the bottom and an arched section on the top, such as a palladium window.  You must order a standard shade with the same width as the arch.  The manufacturer will attach the arch to the top of the rectangular or "standard" shade, giving you one window treatment for the two parts of your window.


Choose this option when your arch is separate from another section of window - that is, the half-circle shape is completely framed in.

last step!

Optional information:

Learn more about optional information

Used on our order forms, the window nickname is one that you assign to the windows in a room.  This helps you keep track of your order when a room has multiple windows.  We recommend including a room name and numbering the windows sequentially (for example, "Bedroom window #2"), but you may use any system you like.

"Great Buy"

by Brandon from Northern, KY on June 11, 2016

I looked everywhere to find an arch shade to fit our arch window that is over a standard window. Lowe's, Home Depot, and several other specialty blinds companies couldn't help me, at least online. I was able to place my order online through Blinds Galore with ease. The blind arrived quickly! However, because Blinds Galore required the height to be exactly two times the width, I had to order the blind knowing that that the blind was going to be too long for my window. Once I received the blind, I cut a half inch off of the width and it fit perfectly. Through this process, I wish that you could order the arch blind to exact specifications.
