Start with the anchor
Above furniture, the complete art group begins around two-thirds to three-quarters of the furniture width.

What the number means
A useful starting point, not a decorating law.
Interior guides converge on a range rather than one perfect number. GeMarkt starts inside that range, then lets your actual wall, furniture and chosen artwork shape change the result.
Fit the real wall
A tall artwork is reduced if the chosen width would crowd the ceiling. Side margins are protected too.
Test the outer edge
The answer includes the frame and group gaps. Use the printed plan, then tape the outline at full size.
The honest limits
Scale can be calculated. Taste still belongs to you.
The 67–75% furniture ratio and a centre around 57–60 inches on an open wall are widely used decorating conventions—not scientific standards. The live coverage control is there because a quiet room and a statement wall can need different answers.
Above furniture, the gap above the object takes priority over forcing every centre to one height. The tool also makes no claim about safe fixings, frame weight, heat above fireplaces, hidden pipes or electrical cables.
Exact sizes and materials vary by product and destination. Use this result to choose the nearest live option; the Etsy listing remains the source of truth before payment.

Common sizing questions
What size art should go above a sofa?
A useful starting range is 67–75% of the sofa’s outer width, measured across the complete artwork or group including frames and gaps. The calculator also checks the available wall height.
Does the frame count in the measurement?
Yes. Use the final outside dimensions, including the frame and mat. For a pair or three-piece row, the total also includes the spaces between frames.
Should every artwork be centred 57 inches from the floor?
No. A centre around 57–60 inches is a useful open-wall starting point. Above furniture, the visual relationship and gap above the furniture normally take priority.
Is the printable plan a drilling template?
No. It is a scaled planning sheet with a printer calibration line and a tape-test checklist. Fixing position depends on the frame hardware, weight and wall construction.
