It's the question we get asked more than any other. You've found the perfect print. You love the colours, the style, the subject. Then comes the moment of uncertainty: what size do I actually order?

Get it right and the art transforms the room. Get it wrong — too small, too large, hung too high — and even a beautiful print can look like an afterthought.

This guide gives you the real numbers: room by room, wall by wall, furniture by furniture. No guesswork.

The golden rule of wall art sizing

Before the room-by-room breakdown, one principle covers nearly every situation:

Most people buy too small.

A print that looks large on a screen — or even in your hands — can disappear on a wall. Walls are bigger than they look when they're empty. The furniture you're hanging above is wider than you remember. And once a frame goes up, the eye wants more of it, not less.

When in doubt, size up. Every time.

How to measure your wall correctly

Before ordering any wall art prints UK, do this:

1. Measure the width of the wall or the furniture piece you're hanging above
2. For art above furniture: your print should be 50–75% of the furniture's width
3. For a feature wall with no furniture: your print can fill 60–85% of the wall width
4. Cut paper to the exact size of the print you're considering and tape it to the wall — live with it for a day before ordering

That last step sounds basic but it works. Scale is genuinely hard to judge without a physical reference.

Standard print sizes — quick reference

All our prints are available in each of these sizes — framed or unframed — so whatever room you're working with, there's a size that fits.

Room-by-room sizing guide

Living room wall art UK

The living room is where sizing mistakes show up most visibly — because it's the room you spend the most time in, and the walls are often the largest in the house.

Above the sofa This is the most common placement and the one most people get wrong. The print should be two-thirds the width of the sofa — no narrower. For a standard 3-seat sofa (roughly 200–220cm wide), that means:

• Minimum: A1 art prints UK (594mm wide) — acceptable but will feel modest
• Ideal: A0 (841mm wide) — fills the space confidently
• Gallery wall: a set of 3 prints UK or set of 5 prints totalling roughly 140–160cm wide

Above a fireplace or sideboard Match the width of the furniture. A sideboard that's 120cm wide calls for an A1 print (594mm) at minimum, or an A0 if you want a statement. For a wide fireplace (150cm+), consider a horizontal diptych art prints UK arrangement or a large A0 in landscape format.

Feature wall with no furniture Go large. An A0 or oversized wall art UK print on an empty feature wall is rarely too big. If the wall is very wide (3m+), consider a set of 2 or 3 prints arranged horizontally — a triptych wall art UK arrangement works beautifully here.

Bedroom wall art UK

In the bedroom, art above the bedhead is the standard — and sizing relative to the bed is the key variable.

Above the bedhead The art should be no wider than the bed frame and ideally sit about 15–20cm above the top of the bedhead.

On a side wall A2 or A1 works well on a bedroom side wall. Bedroom walls suit quieter, more intimate scale — you're not trying to make a bold statement here, but you want enough presence for the print to register.

Dining room prints UK

The dining room sits somewhere between the bedroom and living room in terms of scale — you want presence, but the art shouldn't overwhelm the conversation.

Above a sideboard or buffet Follow the same two-thirds rule as the sofa. For a standard dining sideboard (120–150cm wide), an A1 print is usually the right call. An A0 works if the sideboard is wide and the ceiling is high.

On a feature wall An A0 print creates a dramatic focal point. Alternatively, a gallery wall of 3–5 prints in varying sizes (A3 to A1) adds personality — a set of 3 prints UK in complementary styles is a popular choice here.

Ceiling height consideration Dining rooms often have standard 2.4m ceilings. In this case, keep your art to A1 or below — an A0 portrait print can feel too tall. In a room with higher ceilings (2.7m+), A0 is ideal.

Bathroom prints UK

Bathrooms call for smaller art — and that's actually a good thing, because it means you can invest in a beautifully framed piece without it costing a fortune.

Above the toilet or on a side wall A3 art prints UK (297 × 420mm) is the standard choice for most bathrooms. It's large enough to make a visual impact in a small space without crowding the walls. A2 works in larger bathrooms or on a wider wall.

Vanity wall If you have a wide vanity mirror, resist the urge to hang art directly above it (it competes with the mirror). Instead, hang a small A3 print on an adjacent wall at eye level.

Important: Always frame bathroom art behind glass. Humidity won't damage a quality giclée print inside a sealed frame, but unframed prints will warp.

Hallway prints UK

Hallways have two challenges: they're usually narrow, and they're often long. The goal is art that creates rhythm and welcomes people in without crowding the corridor.

Narrow hallway (under 90cm wide) Stick to A3 or A2 prints, portrait orientation. A series of small prints spaced evenly down the hallway creates a gallery corridor effect — one of the most effective uses of hallway space.

Wide entryway or open hallway An A1 or A0 print on the facing wall as you enter is a strong statement. This is the first thing guests see — make it count. Large wall art UK at this scale transforms an entryway.

Stairwell One of the best opportunities for a gallery wall in the house. Follow the angle of the stair with a diagonal arrangement — mix A3, A2, and A1 sizes, keeping the spacing consistent (around 6–8cm between frames).

Home office art UK

Art in a home office should energise and focus — not distract.

Behind a desk (for video calls) One A1 or A0 print centred behind your chair creates a clean, professional backdrop for calls. Make sure the art is visible in frame without being overpowering — statement wall art UK at this scale creates an excellent backdrop.

Side wall A2 or A1 works well on a side wall. A small gallery arrangement of 2–3 A3 prints can also work if wall space is limited.

How high should I hang my art?

This is where most people go wrong — art hung too high is one of the most common interior design mistakes.

The rule: The centre of the artwork should sit at 145–150cm from the floor — roughly eye level for a standing adult.

The exception is art hung above furniture. In that case, leave a gap of 15–20cm between the top of the furniture and the bottom of the frame. This visually connects the art to the piece below it.

Don't adjust your hanging height based on ceiling height. High ceilings don't mean you hang art higher — the eye-level rule applies regardless.

Framed vs. unframed: does size change?

When sizing framed wall art UK, remember that the frame adds to the overall dimensions. A standard frame profile adds 3–5cm on each side, so an A1 print (594 × 841mm) in a frame will have an overall framed size of roughly 620–700mm wide.

If you're sizing art to fit within a specific space — above a door, between two windows, in a niche — always account for the frame in your measurements.

Quick sizing cheat sheet

Sets of prints: when to buy a set instead of individual pieces

If you're planning a gallery wall or a multi-print arrangement, buying a set of prints UK is almost always better value and better looking than buying individual pieces.

• Set of 2 prints UK — ideal for diptychs above a bed or sideboard
• Set of 3 prints UK — the most popular choice for above-sofa gallery walls and horizontal strips
• Set of 4 prints UK or set of 5 prints UK — for larger salon-style arrangements
• Gallery wall sets UK — curated collections designed to work together, available framed or unframed

Sets take the guesswork out of making prints look cohesive — the palette, style, and sizing is already resolved.

Final thought

The best way to get sizing right is to put something physical on the wall before you order. Cut a piece of paper or brown paper bag to the exact dimensions of the print you're considering — frame included — and tape it up. Step back. Live with it for a day.

You'll almost always find yourself reaching for the size up.
