Wall Art Size Calculator
Calculate the ideal size of wall art for your space using established interior design rules. Art width should be approximately 60–75% of wall width (the "60–75% rule"). For art above furniture (e.g., sofa), art width should be approximately 66–75% of furniture width. The recommended center height is approximately 57–60 inches from floor (eye-level).

How the Wall Art Size Calculator Works
Galleries and framers size art to the wall with a simple proportion rule, and this calculator applies it directly:
Ideal art width = 60–75% of the wall width (or 66–75% of the furniture below it)
Art narrower than about 60% of its wall floats in the empty space and looks lost; wider than 75% crowds the edges. When the art hangs above furniture — a sofa, a console, a bed — the furniture becomes the reference instead of the wall, and the sweet spot narrows slightly to two-thirds or three-quarters of the furniture's width. The calculator also returns a height range (50–67% of wall height) and the hanging height: the center of the artwork at 145–152 cm from the floor, the museum-standard eye level. That last number is the one most homes get wrong — art is hung too high far more often than too low.
How to Size and Hang Art Like a Gallery
Measure the wall section you're actually decorating — from corner to corner if the wall is bare, or the width of the furniture below if the art will crown a sofa or sideboard. For a gallery wall of several pieces, treat the whole arrangement as one artwork: the outer boundary of the group should hit the same 60–75% target, with consistent 5–8 cm gaps between frames.
Before hammering anything, cut paper templates of the frames, tape them up, and step back to the doorway. Ten minutes with painter's tape has saved more walls than any calculator. Hang from the artwork's center, not its top edge: measure 145–152 cm from the floor, then add half the frame height above that point to find the hook position — and if hanging above a sofa, keep the frame's bottom edge 20–25 cm above the backrest regardless.
Think of the wall as a composition: full-height curtains on the same wall shift its visual proportions, so size the two together using the curtain size calculator. And the sofa the art anchors to should itself be proportioned to the room — the sofa size calculator checks that side of the equation.
Art Size Quick Reference
| Situation | Rule | Example |
|---|---|---|
| Bare wall | 60–75% of wall width | 3 m wall → 180–225 cm art |
| Above a sofa | 66–75% of sofa width | 2.2 m sofa → 145–165 cm art |
| Above a bed | 66–75% of headboard | Queen bed → 105–120 cm art |
| Gallery wall | Group counts as one piece | 5–8 cm between frames |
| Hanging height | Center at 145–152 cm | Museum eye level |
Common Mistakes to Avoid
- Hanging art too high — center it at 145–152 cm, which feels low until you step back.
- One small frame on a large wall; either size up or build a gallery group.
- Ignoring the furniture reference and sizing to the whole wall above a sofa.
- Uneven gaps in gallery walls — inconsistent spacing reads as clutter, not curation.
Frequently Asked Questions
How high should I hang wall art?
Place the center of the artwork 145–152 cm from the floor — the eye-level standard museums use. Measure to the artwork's center, not the hook: add half the frame height, minus the drop of the hanging wire, to find where the nail goes. Above seating, also keep 20–25 cm above the backrest.
What size art should go above a sofa?
Two-thirds to three-quarters of the sofa's width. Above a standard 2.2 m three-seater, that's artwork (or a framed group) of 145–165 cm wide. Anything much narrower gets visually swallowed by the sofa; anything wider than the sofa unbalances the composition.
How do I arrange a gallery wall?
Treat the entire group as a single artwork sized at 60–75% of the wall, keep gaps consistent at 5–8 cm, and center the whole composition at 145–152 cm. Lay the arrangement out on the floor first, then transfer it with paper templates before making holes.
Can wall art be too big?
Yes — past about 75% of the wall's width, art starts crowding corners and competing with the architecture instead of decorating it. If you've fallen for an oversized piece, give it a bigger wall or let it lean floor-standing against the wall, which reads as intentional.
