6 Living Room Arch Design Ideas

Want to add some oomph to your living room? If you’re looking at blank walls and thinking, “This space feels…meh,” I get it.

Sometimes, a well-placed arch can transform your living room completely. Whether you prefer modern minimalism or farmhouse chic, arches add character without effort.

And no, we’re not talking about those odd ’90s alcoves your aunt never updated.

Now, let’s explore arch design ideas for your living room.

These ideas not only look great but also pair well with practical, stylish pieces. I’ll share some of my favorite finds that I love. Ready? Let’s dive in.

Add Drama with a Feature Wall Arch

One of the easiest ways to bring in an arch is through a painted or wallpapered feature wall. It draws attention and makes the room feel intentional, even if you still haven’t figured out where to put that giant plant you impulse-bought.

Try This:

Geometric Shapes Arch Wallpaper Abstract Art Wall Mural

Not peel-and-stick, so yeah, you need commitment (and maybe patience).
Abstract art meets architectural edge.
Works beautifully as a backdrop for your TV or sofa.

Why I love it: It adds visual depth and texture without the commitment of construction. Also, I’m not emotionally ready to knock down walls. You?

1. Use Arched Mirrors to Fake It Till You Make It

No arch? No problem. Mirrors with an arched shape give off that architectural vibe without tearing up your drywall.

Product Pick:

Black Arched Window Mirror (31.5 x 20 x1)

Gives the illusion of a window, which is perfect for smaller or darker rooms.
That black metal frame? Chef’s kiss.
Totally farmhouse-approved but still works in modern spaces.

Hot Tip: Put it behind your couch or above your console table. You’ll trick everyone into thinking your space is twice as big and three times as fancy.

2. Highlight with Arched Lighting (Literally)

Lighting is everything. And while we all love natural light, sometimes you need a little help when the sun goes down (or refuses to show up).

Must-Have:

Aipsun Black Modern LED Wall Sconce (Set of 2)

Sleek, up-and-down lighting makes your arch wall pop.
Comes with G9 bulbs and gives off a warm 3000K glow.
Perfect for highlighting art, mirrors, or just setting the mood.

IMO: These are basically the highlighters of the decor world. Pop them on either side of your feature wall or mirror, and boom—instant ambiance.

3. Frame It with Furniture (Yes, Really)

Ever noticed how some furniture just works under an arch? Like it was made for that exact spot? If you’re lucky enough to have a built-in arch nook, try framing it with practical, stylish pieces.

Current Obsession:

Helios & Hestia 6-Panel Folding Room Divider (Dark Grey)

6 feet tall and 120″ wide—seriously, it’s a wall on its own.
Great for creating zones in open-plan living rooms.
Gives major loft vibes, especially if you place it under or beside an arched opening.

Why it rocks: Sometimes you want separation without the drama of actual construction. This room divider gives you that “hidden corner” without hiring a contractor.

4. Go for Gallery Wall Goals

Arches love a good gallery wall. It’s a design marriage that just works. You can either build your gallery wall within an arched shape or use an arched frame to stand out in the mix.

Speaking Of…

Large Framed Black and White Neutral Abstract Wall Art (Set of 3)

24×36 inches each—so yeah, they’re bold.
Minimalist geometric patterns = visual balance.
Perfect backdrop for mid-century modern, boho, or Scandinavian styles.

Pro Tip: Use the center canvas to anchor your arch and build outward with smaller pieces or mirrors. Instant museum vibes, minus the security guard following you around.

5. Mix Arches with Clean Lines

Too many arches can feel like you’re living in a Renaissance painting. (Which, unless you’re Botticelli, might not be the vibe.) Mix things up with clean-lined accessories to avoid visual overload.

Combine These:

The arched mirror for soft curves
The abstract canvas prints for structure
A sleek sconce to tie it all together

It’s like a really good playlist—a mix of smooth transitions and sharp hits.

6. Embrace Symmetry (But Not Too Much)

Designers love symmetry for a reason—it’s pleasing to the eye and feels balanced. But a little asymmetry adds personality.

Place one arched mirror on one side of your fireplace and pair it with a tall plant or floor lamp on the other. Let the room breathe.

Quick Recap of the MVPs:

Aipsun Wall Sconces for ambient glow
Black Arched Window Mirror for faux-window drama
Geometric Arch Wallpaper for artsy flair
Helios&Hestia Room Divider for flexible layout
Black and White Abstract Canvas Set for curated cool

So… Should You Add an Arch?

Yes. But you don’t need to go full-on architecture major to make it work. Whether you’re faking it with a mirror, dressing it up with wallpaper, or highlighting it with lighting, there’s a way to make arches work in literally any living room.

You don’t need a sprawling villa or cathedral ceilings. Just a few smart pieces, a little layout finesse, and maybe a ladder (because seriously, wallpapering is not a solo sport).

Got an arch setup you’re proud of? Or maybe a disaster story that ends with, “So we painted over it…”? Share it. Tag a pic. Let’s swap inspo.

Final Thought: Arches aren’t just architectural flourishes from ancient times. They’re totally in right now, and more importantly, they make your space feel intentional and cozy.

And hey, if your arch obsession spirals into a full home makeover, don’t blame me. (Okay, maybe blame me a little.)
