REALLY!!!! It is a wall do wahtever unless you want to share what the space has in it now and why an accent wall at all. IMO an accent wall is decided after all the other choices have been made for the space . In bedrooms I like using the bedding for my decor so what is your bedding , what is your style, what does the bed look like and really show the whole room in pics here in comments DO NOT start another post . Answer all here in comments.

We didn’t buy bedding yet . Since we will put headboard there so thinking accent wall will be better. This space is empty now we will put king bed after doing something with this wall .

Are you putting nightstands on both sides of the bed? If so, it does not appear to be enough space on that wall.

Artwork on that wall might be enough.

Do you have colors selected? Perhaps you can add wallpaper to the entire wall.

No I didn’t select any color or wallpaper yet - due asymmetrical boundaries. Confused about where to color and where not !

I think you might get more responses if you posted more photos showing the entire space as well as a couple of inspiration rooms.

My last and current home both have bumpouts - vents, hidden fireplace, structural columns. We have a king bed. I just ignored it, decorated the room as I normally would instead of drawing attention to it. Here are pics. I think it looks just fine.

I wouldnt call attention to it with an accent wall. Paint all the walls the same color.

Frame it all out, add drywall, and get rid of the weirdness.

I think accent walls will make these problems seem more intentional than “mistake”…using slightly different shades of the same color on each surface of the wall ..can create an interesting architectural feature..

I would include the ceiling section in this color infusion effect

Put your bed there. Put your nightstands in. Find a big painting, print or poster to go on the wall. I think it will look fine.

If you don’t like the color of the room, or want a dramatic color, do EVERYTHING in that color - even the ceiling. And buy fabulous bedding so you don’t ever look at that weird thing again. Don’t treat the wall differently, like @Kendrah said. Ignore it.

Or wallpaper the whole room with something fabulous and distracting -including the ceiling and weird bump out.

You might consider not accenting that wall, so as to not draw attention to the bump out. Here are a few bedrooms we have designed for our clients. Notice the artwork, lighting, nightstands, and rugs.
