I agree with nothing that is just grey and white.

I suggest that you use painter's tape to decide on a size for whatever art you might choose. It seems that the space calls for something large. This could be art, a quilt, a weaving, or a poster. Some of these might be placeholders until yo someday find the piece that speaks to you.

I love a lot of color in my living room. Look into a local artist or art gallery. Or get on art.com. There are a lot of options there. Buy a print and get it framed locally with plexiglass (safer and easier to hang).

I’d want something with a bit more height - i think the tapestries from anthropologie are fun and a total steal for the scale

Add some wall art with color, but also some accessories that help pull the colors down into the seating area. Color will help give the space some warmth.

depends on the budget by ETSY.com has a lot of great Wabi Sabi art pieces

large enough for your wall.

I like something like this

Maybe trees for their irregular shapes and a color other than gray (green)? Looks like you're blocking the view out the lower windows anyway.

Art wouldn't have to be huge (Claude notwithstanding). This is a black and white photograph of the Louvre pyramid. I like the way the pyramid echoes the diagonals of the rug.

Introduce a bit of another color?

Go for drama?

Do you or your husband have any interests?

The grey and white is too much grey for your space. I agree with Claude on that.

Speaking of Claude- you could look at large prints/posters; and coincidentally, Claude Monet comes to my mind.

You do not need gigantic art. You see by the visuals that @simplynatural posted, there is a wide range, as far as sizes.

Etsy.com is a good resource for all kinds of art.

Do not look for art to ”match” the room. Yes, art ‘can‘ complement the colors and style/aesthetic of a space. But it can also just stand on its own. Art is art.

My wish for you is that you find some type of art that inspires you to put it on your wall. Not just something to fill the space.

Right now the only real color you have in the room is the blue and yellow green in the windows. An all gray and white color scheme is pretty monotonous and will become more so as time goes on. So, as others have suggested, find wall art that inspires you and looks good, of course, in your room. Then use it to address the lack of color in the rest of the room. Since your furnishing are rather bland will suggest instead of dark and dramatic that you go in the direction of bright and cheery for your art.

I have no idea about Claude but IMO you need a vertical piece not horizontal and something not so insipid but more exciting . Use that to add color to the space too. You buy art becuse you love it not on someone elses idea of what you should get. I never tell my clients what art to choose .

Something OTHER than gray & white. You already have more than enough of that, no offense. There are tons of sources online for art, what colors other than gray &/white , do you like? Your room needs color, interest, via different sofa pillows, accessories & perhaps a few live plants or trees to bring life to the room, as well as art that you love.

Yes to large-ish and vertical, no to grey and white or anything too pallid.

Proportions and placing vertically are key to creating a balanced wall.

The art’s design is as important as the color combination. Choose what resonates with you and your husband and tie in with impactful coordinated cushions.

Yes, I would absolutely bring in some color. Adding more gray and white at this point will likely make the room feel flat and one-dimensional, especially with such a large wall to fill. Right now, your living room needs a focal point that adds warmth, depth, and visual interest.

Because you have high ceilings and beautiful natural light streaming in from those upper windows, I'd lean toward a large vertical artwork featuring deep navy or sapphire blues paired with rich ochre, mustard, or warm golden tones. Those deeper blues will create a sophisticated contrast against the gray sofas, while the warmer accents will catch the daylight and keep the space from feeling cold or overly monochromatic.

If possible, look for a piece with subtle texture or gold-leaf details. The way those metallic elements reflect natural light throughout the day can completely transform the feel of the room. Instead of the wall fading into the background, the artwork becomes a strong visual anchor that ties the entire space together and gives it a more elevated, designer-finished look.

COLOR please and art is something you buy becuse you love it not because it matches the room If you love it it will work in any space . My advice go shopping in art galleries and see what you both are drawn to then look for art online if you cannot afford the gallery prices. I send my clients to art college if there is one in your city there you can meet the artist and maybe even commission a piece in the right size and style you love . To just slap a pice on that wall to fill it is IMO the wrong choice .I agree color from the art opens a whole array of choices for accents for sure..

A tall vibrant art piece is needed to break up the gray. It should be tall enough to hang in line with the top of the lower windows to form an imaginary horizontal line to break the verticality of the room and bring the ceiling to more human proportions. Or, two related square art pieces can be stacked to form the same effect. As mentioned in earlier posts, the colors of the art can be used in choosing accessories.

Before focusing on art, I would work on the existing issues. The seating all matches. The tables match. A room is more interesting if there is variation. I would trade out the loveseat for 2 occasional chairs that have some brown toned wood and maybe a fun patterned fabric (not gray). Bring in some side tables that have brass and/or wood. Bring in colorful throw pillows. Good luck!

My first thought was large. Red/yellow/blue abstract. Something like this: Color and Play | Great Big Canvas

hung at the window level for balance.

So far not one comment, thanks, or even a like from the OP so they get nothing from me.

Hello from Adelaide,South Australia. Grey can be beautiful, but grey walls, grey furniture, grey rug, they are all far too draining and the room looks lifeless. I agree with Hollywaterfall, tall and large red/blue maybe yelllow abstract print. Grey looks attractive with natural wood, but I dont see any in the room. Personally I would paint window wall an attractive green. Not vivid, subtle, I cant give you the colour, as you have different names for shades of paint in US. Also get some interesting real green plants to give the room some life! Bright cushions will help.

I am with tracefloyd really why post the question if you have no thought of coming back to answer ours

I was taking in all of your comments and did not realize I was expected to comment back. Thank you all for your thoughtful suggestions! This is what I ended up going with. :)

This is AI? Do you have a real pic.

Looks great. Hope you enjoy your room!

Yes it's AI but the frame is a nice size and height and the art colors bring in warmth.

Very nice! I hope it’s a piece that you love, that is the main thing.✨

It really looks great. I can say, from purely a design perspective: It’s a great size and shape; and the colors are excellent for adding contrast and warmth to your space. And the AI image contains some nice details. I don’t know how many of the details were specified by you, and how much of it is AI; in either case, there are some nice ideas there. I love the black shaded floor lamp, the throw pillows including the one black, etc. Beautiful. It’s all in the details! :)
