The wall art size calculator from Kahana Designs, a Native Hawaiian–owned studio in Kailua-Kona, Hawaiʻi, is a free tool that recommends the ideal canvas print size for your wall in seconds, based on interior-design rules of thumb.
Hanging a piece of art that's too small for the wall is one of the most common (and most fixable) decorating mistakes. This calculator takes the guesswork out of it: enter your wall's dimensions, tell it where the piece is going, and it hands back a recommended print size plus a couple of solid alternatives — with a simple visual so you can picture the proportions before you buy.
What is the wall art size calculator?
It's a free browser tool that applies the same rules interior designers use — that art should span roughly two-thirds to three-quarters of the wall or furniture it hangs above, with its center at about 57–60 inches from the floor (standard eye level) — and turns those rules into a specific size recommendation for your space.
How do I use the wall art size calculator?
- Enter your wall's width and height in inches.
- Choose where the piece is going: above a sofa, bed, or console; an open statement wall; or a gallery wall grouping.
- Pick your preferred orientation — landscape, portrait, or square.
- Select "Find my ideal size" to see your recommended print size, a couple of good alternatives, and a scaled visual of how it will look on your wall.
What size art should go above a sofa?
Art above a sofa should be about two-thirds to three-quarters of the sofa's width. For a standard 84-inch sofa, that's roughly a 55 to 63 inch wide piece or grouping, hung with the bottom edge about 8 to 10 inches above the back of the sofa.
How high should I hang wall art?
Hang art so its center sits about 57 to 60 inches from the floor — standard gallery eye level. Above furniture, leave roughly 8 to 12 inches between the top of the furniture and the bottom of the frame so the piece relates visually to what's below it.
Is one large print or a gallery wall better?
Both work well; it comes down to the look you want. A single large canvas makes a bold, calm statement and is the easiest to hang, while a gallery wall of several smaller prints adds personality and flexibility. Either way, aim for the full arrangement to fill about two-thirds of the available wall.
A quiet word on the art itself
Once you know your size, what you put on the wall matters just as much as how it's hung. At Kahana Designs, each canvas is a richly textured digital oil painting of a real Hawaiian place — a North Shore sunset, a Kauaʻi beach, a Big Island volcano — created to bring a genuine sense of place into a home, not a generic tropical print. Browse our Hawaii Art collection to find a canvas sized to fit the wall you just measured.
