Most people go too small. It’s the most common mistake with wall art, and it’s easy to understand why. A print looks substantial on a website. It arrives, you hang it, and somehow the wall swallows it whole.
From years of curating interiors, the same pattern repeats across real homes, not just styled spaces.
The good news: there are practical rules that take the guesswork out of this. Interior designers have used them for decades. Once you know them, sizing becomes one of the easier decisions you’ll make.
This guide walks through every common room, gives you exact size recommendations, and helps you make a choice you’ll feel confident about.
Key Takeaways
- Art should cover 60–75% of the width of the furniture below it
- Standard hanging height is 145 cm from floor to artwork centre
- 50 × 70 cm is the most versatile size for most rooms
- Going bigger than your first instinct is almost always right
Why Size Matters More Than Style
The wrong size doesn’t just look off. It changes how a room feels.
Oversized art on a large wall makes a room feel more open and considered. Undersized art makes the same room feel unfinished, like a decision that was never quite made. The most common regret people report with wall art isn’t the wrong style or colour. It’s buying too small.
When in doubt, go one size up from your first instinct.
The Sizing Rules Worth Knowing
The 60–75% rule
Art hung above a piece of furniture should cover roughly 60–75% of that furniture’s width. A sofa at 220 cm wide wants art that spans around 130–165 cm.
Eye-level hanging
The centre of your artwork should sit at 145–152 cm from the floor.
Gap from furniture
Leave 15–20 cm between the furniture and the bottom of the frame.
Living Room: Above a Sofa
A single 70 × 100 cm print works above a smaller sofa. For a standard three-seater, you’ll likely want a pair of 50 × 70 cm prints side by side, or a 70 × 100 cm flanked by smaller pieces.
A single A2 print above a large sofa will almost always look undersized. The print isn’t the problem. It’s a proportion issue.
Quick reference:
- Small sofa (up to 160 cm): one A2 or 50 × 70 cm
- Standard sofa (180–220 cm): two 50 × 70 cm or one 70 × 100 cm
- Large sofa (220 cm+): three A2 prints or a 70 × 100 cm with supporting pieces
Bedroom: Above the Bed
The bed is the largest piece in the room, which makes the wall above it the most visually important.
A common mistake is measuring only the headboard. Visually, the bed reads as the full width including pillows. Measure edge to edge, then apply the 60–75% rule.
Quick reference:
- Single: one 50 × 70 cm or two A3 prints
- Queen: one 70 × 100 cm or two 50 × 70 cm
- King: two 50 × 70 cm with spacing or three A2 prints
Keep 15–20 cm between the top of the headboard and the frame.
Hallways: Narrow Walls Work Differently
In a hallway, viewing distance is short. The usual rules shift slightly.
Go taller and narrower. A3 in portrait works well in tighter spaces. A2 or 50 × 70 cm works in wider hallways. Landscape prints tend to compete with the architecture.
Three A3 prints aligned consistently create rhythm without crowding.
Home Office and Desk Walls
A desk wall is more intimate than a living room. You’re closer to the artwork, so scale reads differently.
An A3 print can feel substantial here in a way it wouldn’t above a sofa.
Quick reference:
- Small desk: A4 or A3
- Standard desk: A3 or A2
- Full wall: 50 × 70 cm or 70 × 100 cm
Lower the hanging height slightly to seated eye level, around 100–115 cm.
Where Each Print Size Works
A4 (21 × 30 cm)
Shelves, desks, small spaces, or gallery walls.
A3 (30 × 42 cm)
Hallways, desks, and smaller walls. Works well in pairs.
A2 (42 × 59 cm)
A strong mid-size. Works alone on smaller walls or as part of a grouping.
50 × 70 cm
The most versatile size. Works in most rooms and layouts.
70 × 100 cm
A statement piece for larger walls and open spaces.
FAQ
What’s the most common sizing mistake?
Going too small. Art that covers less than 60% of the furniture below it looks accidental.
How do I size a gallery wall?
The full arrangement should follow the 60–75% rule, not each individual piece. Start with one anchor print and build around it.
Can I hang a 70 × 100 cm print in a small room?
Yes, if the wall is relatively clear. Large art can make a small room feel bigger when it isn’t competing with too much else.
Best size for rentals?
A3 and 50 × 70 cm. Easy to hang, easy to move, and flexible across spaces.
Putting It Together
Sizing art isn’t complicated once you have a few anchors. The 60–75% rule, the hanging height, and spacing from furniture remove most of the uncertainty.
Stop defaulting to small. A well-sized print makes a room feel complete. One that’s too small tends to disappear.
If you’re unsure, start with 50 × 70 cm. It’s the most reliable starting point across different rooms.
