10 Creative Ideas for Decorating a 19 x 19 Living Room: Personal design tips, layout strategies, and decor ideas from a veteran interior designer

Over the last decade, I’ve found that large square living rooms, like a 19 x 19 space, can be both exciting and challenging. Current interior design trends lean toward airy, multi-functional spaces — and honestly, a room of this size gives you plenty of room to play. I always say: big rooms can be cozy too if you layer the right textures, lighting, and zoning. Today, I’m sharing 10 of my favorite decorating ideas for a 19 x 19 living room, blending personal experience with expert-backed data.

1. Create Distinct Zones

My Take: In one client’s 19 x 19 living room, we created a seating area, a reading nook, and a small home office in one cohesive space. Zoning makes a big room feel purposeful.

Pros: Helps break up the space; supports multiple activities; works beautifully with open floor plan living room layouts (open-plan furniture arrangement can help you visualize).

Cons: Without clear boundaries, zones can feel cluttered or disconnected.

Tip: Use rugs, lighting, or shelving to define each zone; keep consistent color palettes to unify them.

2. Anchor with a Large Rug

My Take: Oversized rugs instantly bring warmth and ground furniture in a big square room. I’ve saved many designs from feeling ‘floaty’ by adding the right rug.

Pros: Creates cohesion between furniture; adds texture and comfort; can introduce color or pattern.

Cons: Custom rugs for 19 x 19 spaces can be pricey; heavy rugs are harder to clean.

Tip: Aim for at least the front legs of all seating to sit on the rug for a balanced look.

3. Layer Your Lighting

My Take: A single overhead fixture won’t cut it in a large room. I mix recessed lights, floor lamps, and sconces to create depth and warmth.

Pros: Multiple lighting sources help set the mood; highlights architectural features; reduces harsh shadows.

Cons: More fixtures = more wiring and potentially higher energy use.

Tip: Dimmer switches are a game-changer in multi-use living rooms.

4. Statement Ceiling Treatment

My Take: For a recent renovation, we added a coffered ceiling painted in a warm tone — it drew eyes upward and balanced the proportions.

Pros: Adds character; makes tall rooms feel cozier; aligns with luxury interior design trends (source: Architectural Digest).

Cons: Costs can escalate with custom millwork; not ideal if your ceiling height is low.

5. Play with Symmetry

My Take: In a square room, symmetry feels natural. Matching sofas facing each other with a coffee table in the middle can make the room inviting and formal.

Pros: Gives balance; easy to arrange; works well for entertaining.

Cons: If too rigid, it can look overly staged and less relaxed.

6. Incorporate a Statement Sofa

My Take: I once used a deep emerald green velvet sectional in a 19 x 19 room — it became the conversation starter for every guest.

Pros: Defines the main seating area; can introduce bold color or texture; serves as a focal point (statement seating layout tools help visualize proportions).

Cons: Large statement pieces limit flexibility in rearranging furniture.

Tip: If you invest in a bold sofa, keep other large elements neutral.

7. Use Tall Shelving or Built-ins

My Take: Tall bookshelves not only offer storage but also accentuate the height of the room.

Pros: Adds vertical interest; extra storage; can double as display space.

Cons: Can feel overwhelming if filled too heavily; requires stable anchoring for safety.

8. Add Greenery at Multiple Heights

My Take: In big living rooms, plants help break up sight lines. I love combining tall palms with table-top succulents.

Pros: Improves air quality; adds organic texture; enhances biophilic design (source: Harvard T.H. Chan School of Public Health research).

Cons: Larger plants need more maintenance and can block light.

9. Bold Art for Large Walls

My Take: Empty walls in a 19 x 19 room can make it feel cold. Oversized art or a curated gallery wall adds personality and life.

Pros: Fills visual void; reflects your style; can be swapped seasonally (wall decor arrangement can be mapped before drilling).

Cons: Large art pieces can be expensive; requires planning to hang safely.

10. Soften Acoustics with Textiles

My Take: Large square living rooms can echo. I incorporate layered curtains, upholstered pieces, and rugs to absorb sound.

Pros: Creates a cozy, echo-free space; improves acoustics for movie nights or music; aligns with comfort-focused interior trends.

Cons: Can trap dust; requires regular cleaning.
