Wall Art Size Calculator
Right-size and hang art for your wall or furniture
How big should wall art be?
The most common mistake with wall art is hanging a piece that is too small and too high. Art that floats alone in a sea of wall, or sits at forehead height, never looks settled. Two simple rules fix almost every case: size the art to the wall or furniture below it, and hang it at eye level. This wall art calculator applies both — it recommends a width for your space and tells you exactly how high to hang it.
The width rule is proportional: a piece — or a group of pieces treated as one — should span about two-thirds to three-quarters of the width of the wall or furniture it decorates. That is wide enough to feel anchored without overwhelming the space.
Where you hang it changes the height
- On an open wall: centre the art about 57–60 inches from the floor. That is the eye-level standard galleries use, and it works in almost any room.
- Above furniture: forget eye level and use the furniture instead — keep the bottom edge roughly 6 to 10 inches above the top of the sofa or console so the art and furniture read as one group.
When one piece isn't the answer
On a wide wall the recommended width can exceed what a single affordable print offers. That is the moment to switch to a pair, a triptych, or a small gallery grouping: several pieces, hung with even gaps and treated as one block, fill the same span for less money and often look more interesting than one large canvas. The proportion rule still applies to the group as a whole.
Frequently asked questions
How high should I hang a picture? Centre it about 57 to 60 inches from the floor on an open wall — the height galleries hang to, so the middle of the work meets an average person's eye. The frequent error is hanging too high; when in doubt, go a little lower.
How wide should art be over a sofa? Aim for roughly two-thirds to three-quarters of the sofa's width. A sofa about 72 inches wide suits art or a grouping about 48 to 54 inches wide, with the bottom edge 6 to 10 inches above the sofa back.
What if the wall is very large? Scale up, but you will often do better with a grouping than a single enormous piece. Treat the cluster as one rectangle and size that rectangle to two-thirds of the wall or furniture.
Does the rule change for a vertical or narrow wall? The proportion still holds, but orient the art to the space: a tall, narrow wall wants a portrait piece or a vertical stack, sized to the width available rather than the height.
