Do you want floor length? I have a wall of short windows with a patio door in the middle and I used natural linen panels across the entire wall, ~ 15'. I keep them pulled closed for privacy but easy peasy to pull open enough for the door. One day, out of the clear blue, my usually clueless husband said, "Those curtains were a good idea."

You could do one set of panels over the 2 windows and then another set over the wider window; art or chest in between. That could make a balanced look on each side of the wall space. Note: I can't tell if you have the sofa against the wall or if there is space behind it.

nice idea — not much space behind the sofa.. (it’s a bit of a narrow living room)

You can do this if you are willing to spend the money and have a custom window treatment done. Go ahead and do your solar shades for sun control and privacy. Then have custom faux Roman shades made that go to the top of the wall and come down to just past the top of the window. This will hide the tops of the shades and also give the illusion that your windows are taller. Have stationary side panels made in the same fabric that go all the way up! The only thing that will be operational will be the solar shades.

Thanks so much!

Top down shades will also look good. These shades will give the illusion of more space and as you said the living room is not big so covering the windows altogether will further narrow it down.

It doesn’t look like you need much privacy...why not do pretty reed or bamboo shades that come with an attached fringed valance ...they provide shade and a reasonable amount of privacy.... if you are not right on a street or close to a neighbor....

They also offeran organic texture and add a more decorative look than the plain white shades...

Cream Roman blinds to keep it simple and on the empty wall area add art and it should feel well balance.

I love floor length draperies but not with the sill or ledge you have. Use a nice Roman Shade in a texture like pictured above or fabric.

Thanks! What do u think about plantation shutters or wooden blinds? Or was thinking about the shades + short curtains option someone suggested above

I wouldn't do short curtains - they are kind of dated. You could totally do plantation shutters or wooden blinds. I'd probably prefer the blinds.

Consider both white mini blinds -- the new wider slat faux wood kind without the strings -- and a window length (long side) swag valance in your favorite color that you hang with a wide rod close to the ceiling so the swag valance covers the top of the blinds and the top and sides of the window frames but leaves as much glass and natural light showing as possible .

I think the plantation shutters are more at home in tropical settings and are pretty limiting as to your decor choices

Because your windows are sliders, you might also at least consider window length wood vertical blinds. Yes, a lot of the pros here at Houzz hate vertical blinds but they do work well with sliding glass patio doors and horizontal sliding windows, especially if the windows going to be used as a pass thru window for a porch or deck or patio. Unlike standard up/down blinds that seem to need something more for the window to be complete, the window looks complete with the vertical wood blinds in a family room. (Not so much in a formal room.) Vertical blinds also come in faux wood or fabric or vinyl in a lot of different colors.

Wooden or rattan (dark brown may be too dark) ) are the most economical way to go and will look nice. Use complimentary art on middle wall, cushions and even a rug to tie everything together

I think all the options are probably set for you.... but the wide panels that Ikea has- if had 2 of them, drywall space in the middle could be their stacking place, so each slides across the windows going out .... for fun you hang 'dummy panels' at sides.... just an idea!

Contemporary casual, not so different visually than wainscoting that has another color [another color on upper drywall] - here it is: install curtains all across the upper wall / paint lower whatever, maybe same as sofa, and rest of room would have to work in that direction.

"Lill" curtains can be cut to the desired length without hemming. Each panel Length: 98 " Width: 110 "

BBBeyond joiner if spring rods used inside mount on wide windows.
