The sofa is modern, color grey from leather, 2.45 meter long. The wall is white.

I attach a photo of the room and a painting that was hanging before, 1.30X1.00. I’m not sure about hanging it back after changing the sofa.

I tend to prefer either a gallery wall that encompasses both large and small items or an oversized piece of artwork. I plugged your metric conversions into Google so I see the image is about 4 x3 feet. That would work but I wouldn't use it alone. If you love it--and only if you truly love it--consider making it part of a gallery wall. If you google gallery walls, you'll get a nice idea of how different people make them work, here, on Apartment Therapy, and all over Google.

Best of luck! Only use things you love and it will be fantastic!

Thanks a lot. It was very helpful. I have to think again now.

those visuals are helpful but what gets me is that of course, in reality, I have so many differing sized items and not many that are duplicates. Still quite helpful though so thank you

I do not like gallery walls except in hallways with family photos I find then rarely done well and I much prefer one large piece of art you love .

I agree with you.

A big bold painting brings serious flair, and can instantly change the vibe of any space. Whether hung above a bed , sofa or elsewhere in the room, a painting can create a focal point with impact and add both color and dimension.
