A quick reference, not a rulebook
These are starting ratios I use when briefing scale with clients and studios - useful as a fast reference, but always adjusted for the actual room, ceiling height, and surrounding furniture.
Above a sofa
Artwork width should sit at roughly two-thirds to three-quarters of the sofa's width. For a standard three-seater around 2 metres wide, that puts the artwork in the 1.3 to 1.5 metre range. Leave 15 to 25cm of breathing room between the top of the sofa back and the bottom of the frame.
Above a bed
Similar logic applies - two-thirds to three-quarters of the bedhead width for a single piece. For a queen or king bed, this often lands a large single work in the 1.2 to 1.8 metre range, which is exactly the scale I most often work at for bedroom commissions.
Above a console or sideboard
Consoles are narrower, so the same ratio produces a smaller, more vertical-leaning piece relative to a sofa wall. This is often the right spot for a striking but more intimate work rather than the largest piece in the room.
On an open, freestanding wall
Without furniture to anchor against, go by the wall itself. Most freestanding walls in living spaces and entries can comfortably take more scale than clients expect - this is where undersizing is the most common and most easily avoided mistake.
When the ratio and the room disagree
Ceiling height, adjoining sightlines, and how much else is happening visually in the space all override a simple ratio. This is exactly why I prefer to confirm scale against real room photos or a site visit before production begins, rather than working purely off dimensions on a plan.
Get scale right from the start
Send me your wall dimensions and a photo of the space and I will advise on the right scale before we discuss anything else. Use the commission enquiry form below to start.
