Choosing the right size for art can completely transform your space. Whether you're decorating above a couch, filling a blank hallway, or building a gallery wall, scale matters. Too small and it disappears. Too big and it overpowers the room. This guide breaks down how to size wall art for every space so you can find the perfect fit the first time.
Key Takeaways
- Wall art should take up about 2/3 to 3/4 of the width of the furniture it's hanging above
- Measure your space before shopping to avoid art that's too small or too large
- Oversized wall art (e.g. 36x48") makes a bold impact in large living rooms
- Mix sizes in gallery walls, but keep spacing tight and cohesive
Best Wall Art Sizes for Over a Couch
A common spot for canvas wall art is above the sofa. Here’s the rule: your art should be about 2/3 the width of the couch.
- For standard 84" couches, aim for art around 48" to 60" wide
- Use one large canvas or a pair of medium-sized prints (diptychs or triptychs)
- Keep the bottom edge of the art about 6" to 8" above the top of the couch
Wall Art Size Guide by Room
Use this cheat sheet to guide your sizing based on room type:
- Living Room: 36x48", 30x40", or a set of 2–3 medium canvases
- Bedroom (above bed): 30x40" or 24x36" horizontally oriented
- Dining Room: 24x36", 20x30", or triptychs for long walls
- Entryway: Smaller sizes like 16x20" or 12x16" depending on layout
- Hallway: Vertical pieces or gallery sets, 11x14" to 18x24"
When to Go Oversized With Your Wall Art
Oversized canvas prints (36x48" or larger) are great for making a bold statement, especially in open-concept living rooms or bedrooms with high ceilings.
- Works best above sectionals, mantels, or in dining areas
- Choose simple designs like neutral abstracts or nature landscapes to avoid overwhelming the space
- For balance, make sure the art is centered with equal wall space on either side
Best Wall Art Sizes for Gallery Walls
Gallery walls offer flexibility, but planning the layout is key. Start by picking a focal piece and build around it.
- Use one 16x20" or 18x24" as the anchor
- Surround with smaller sizes like 8x10" and 11x14"
- Keep 2" to 3" spacing between each piece for a clean layout
- Align the centers, not the tops, for a balanced look
Pro tip: Lay everything out on the floor or use painter’s tape on the wall before hanging.
Wall Art Sizing for Small Spaces
For apartments, condos, and small rooms:
- Stick to lighter colors and minimalist designs
- Use 16x20" or 18x24" for main walls
- Avoid clutter—one well-sized piece is better than a bunch of tiny ones

Framed vs. Unframed Canvas Wall Art: Size Considerations
Remember that frames add visual weight. A 24x36" framed print will feel larger than a 24x36" canvas without a frame.
- Go slightly smaller if you're framing the art yourself
- Choose floating frames or minimal borders for a clean, modern look
- Framed canvas art is a great in-between option that gives polish without the bulk of glass
How to Measure Your Wall Before Buying
- Measure your wall width and height
- Visualize the ideal artwork size (2/3 of the wall or furniture below it)
- Tape off the outline on your wall with painter's tape
- Step back and adjust as needed
This simple step can save you returns and regrets.
Frequently Asked Questions
What size wall art is best over a queen bed?
Try a piece that’s 30x40" or two 20x30" prints side-by-side. It should be centered and hang 6–8" above the headboard.
How big should wall art be above a fireplace?
Aim for something around 36" wide for standard fireplaces. Keep it centered and leave a few inches of breathing room.
Is it okay to hang small art on a big wall?
Only if you're grouping it with others. One small piece on a large wall can feel off unless it's part of a gallery or paired with other decor.
Final Thought: Size Matters More Than You Think
Wall art isn't just decor—it sets the tone of your entire room. The right size can make your space feel finished, balanced, and truly designed. Whether you’re decorating above a couch, curating a gallery wall, or adding a focal point to a small nook, getting the proportions right changes everything.
Still deciding on the best size for your space? Start by measuring, visualizing, and using the simple 2/3 rule as your guide. And when in doubt, go slightly bigger than you think—it almost always looks better than something too small.
