The 60-75% rule explained: measuring art width against sofa or console width
A wall panel that stays with you for decades deserves to sit right the first time. The most reliable starting point is simple: the art above a piece of furniture should span roughly 60-75% of that furniture's width. A sofa, a console, a bed — the number holds.
Measure the furniture at its widest point. For a 200 cm sofa, the target range for your panel's longer side is 120-150 cm. Aim for the middle of that range when in doubt: 135 cm reads as intentional, not timid, not overbearing.
Our sizes run by the longer side: S (45 cm), M (60 cm), L (80 cm), XL (100 cm), XXL (130 cm). For that 200 cm sofa, an XXL at 130 cm lands cleanly inside the range. A single L at 80 cm would float — too small, adrift above the seat back. That is the miscalculation that costs you a return.
One caveat for metal: the real dimensions depend on the design's aspect ratio. The shorter side scales proportionally — an S at 3:2 is 45×30 cm. Read the longer side as your anchor, then check the height against the wall you have.
Wall-fill ratios: how much negative space to leave for balance
Furniture width sets the scale. The wall around it sets the breathing room. Negative space is not empty — it is the frame that lets the piece register as a piece.
A working ratio: on an open wall with no furniture beneath, aim for the art to occupy 50-60% of the available wall width, leaving even margins left and right. Crowd the edges and the panel feels trapped; strand it in the middle of a large wall at too small a size and it disappears.
Height matters as much as width. Hang so the centre of the piece sits at roughly 145-150 cm from the floor — eye level for most people standing. Above a sofa, drop that: leave 15-25 cm between the top of the seat back and the bottom of the panel, so the two read as a group rather than two unrelated objects.
- Large empty wall: L, XL, or XXL. Small sizes vanish here.
- Narrow hallway or between windows: S or M. Restraint reads as confidence.
- Above furniture: 60-75% of the furniture width, centred, with a deliberate gap beneath.

Adapting formulas for metal art: visual weight vs. actual dimensions
Framed prints and canvases behave predictably: the outline is the object. Laser-cut steel does not. A cut-out silhouette and a solid figure of the same nominal size carry very different visual weight — and that changes how the sizing rules apply.
An airy, open design — a branch, a script line, a bird mid-flight — reads lighter than its dimensions suggest. The wall shows through it. For these, you can push toward the upper end of the 60-75% range, or even slightly beyond, without the piece feeling heavy.
A dense, filled silhouette does the opposite. It holds its full footprint visually and can dominate a wall faster than the tape measure predicts. For these, stay mid-range or lower.
Then there is the shadow. Mounted on standoffs, the panel lifts off the wall — usually around a centimetre — and casts a designed shadow that shifts through the day. That shadow extends the visual presence beyond the steel edge. A piece on standoffs occupies more perceptual space than the same piece mounted flush. If you want a smaller physical footprint to still command a wall, standoffs do that work for you.
Weight, in the literal sense, follows area. Two-millimetre steel runs about 16 kg/m², so a panel's mass grows with its surface — an open, tracery design weighs less than a solid figure of the same size. [do weryfikacji: dokładne wagi per rozmiar zależą od procentu wycięcia] An M-sized panel at around 2 kg holds on standard plasterboard anchors without ceremony.
Worked examples: standard sofa, king bed headboard, and gallery wall calculations
Numbers make the abstract concrete. Three common cases:
Standard three-seat sofa (200 cm)
Target width: 200 × 0.60 to 0.75 = 120-150 cm. An XXL panel (130 cm longer side) sits centred inside the range. Hang the centre roughly 20 cm above the seat back. If your design runs tall and narrow, check the height clears any picture rail or ceiling line before committing.
King bed headboard (approx. 160-180 cm)
Take the headboard, not the mattress, as your reference. For a 160 cm headboard: 160 × 0.60 to 0.75 = 96-120 cm. An XL panel (100 cm) is the clean fit. Centre it on the bed's midline, not the wall's — the eye reads the piece against the bed, and an off-centre bed makes a wall-centred panel look wrong.
Gallery wall of three panels
Treat the group as one object. Measure the total span you want the arrangement to cover — say 75% of a 240 cm wall = 180 cm. Three M panels (60 cm each) plus two 10 cm gaps between them = 200 cm, slightly wide; tighten the gaps to 6 cm and you land at 192 cm, comfortable. Keep vertical centres aligned or run a consistent baseline. The gaps are part of the composition — even spacing is what makes three separate pieces read as one intentional wall.
Before any of these, use the wall preview and the RAL configurator together: see the piece at scale, in your chosen finish, on your actual wall. Get it right on screen, and it stays right for twenty-five years.
