How To Put Up Wood Blinds Over Patio Doors The Easier Way

There are several ways to put up wood blinds over patio doors.

One way:
You can choose to mount them right on the doors as an outside mount.

It would look something like this…

Wood Blinds On Patio Doors - An Outside Mount

Another way:
An outside-mount on the drywall covering a door or doors and the entire opening, including casings is an option, too.

Yet another way to mount wood blinds over two patio doors side-by-side is this one (if that's the door frame you have)…

Two Wood Blinds Over Patio Doors As An Inside Mount

Here, we have two patio doors.
One has a screen with hardware on the right side that partially opens the door to the outside (L).

The right door swings open to the *outside* (R).

Simply put, the situation you see resembles having "two regular windows" with a frame around them deep enough to fit an inside-mount installation of window blinds and shades.

To keep the installation of the two wood blinds uniform and to protect the wood blind on the right door from getting *weathered* from time to time (if mounted as shown on the first picture and opening to the outside), we have a nice and clean option of installing the two wood blinds side-by-side as an inside-mount installation within the door frame (L & R).

Account For An Extra Space For The Hardware Handle (L Side: Note the extra space between the slat ends, the hardware handle and the door jamb.)

As you can see, the hardware protrudes into the path of the wood blinds over the left door.

The measurement was done as an inside mount, but the WIDTH was taken from left to right up to the hardware handle.
The factory took deductions. The wood blind, as you can see, does have enough space to clear the "hardware obstruction" in its path.

The only "miss" was the valance that the factory forgot to send a bit wider despite ordering instructions. 
(A special ordering note for the valance width is necessary in this case because the inside-mount width of the blind is a bit less due to the door opening hardware.)

The Left Valance Needs An Extra Inch To Cover The Small Gap And To Look As Flush With The Wood Frame As The One On The Right

In the above picture, the valance does cover the mounting bracket, but shows the remaining gap to the wood frame.
