How big 30x40 really looks

Where a 30x40 print fits
It suits the wall above a dresser, a loveseat or a queen bed, the main wall of a dining room, and a pair above a long sofa.
- In portrait, a 30 × 40 print is 76 cm (30 in) wide, so on its own it suits furniture 102 to 114 cm wide, such as a chest of drawers, a desk and a console.
- In landscape, a 30 × 40 print is 102 cm (40 in) wide, so on its own it suits furniture 135 to 152 cm wide, such as a dresser, a loveseat and a queen bed.
- Above a three-seat sofa 220 cm wide, 2 portrait prints in a row, 6 cm apart, fill the two thirds of the sofa’s width that looks right.
How high to hang it
On a bare wall, hang a 30 × 40 print with its centre 145 to 152 cm (57 to 60 in) from the floor, the eye level galleries use. Above a sofa 85 cm high, keep 15 to 25 cm between the sofa and the frame, which puts the centre of a landscape 30 × 40 at about 148 cm (58 in). At 30 × 40, the work sets the tone of the room. Leave at least 30 cm of clear wall on each side so it can breathe.
Framing a 30x40 print
A 30 × 40 work is often sold as a stretched canvas with no frame, or in a floater frame that leaves a small gap around the canvas.

The file a sharp 30x40 print needs
Print shops ask for 300 dpi, which at 30 × 40 means 9,000 × 12,000 pixels. From the viewing distance above, 150 dpi (4,500 × 6,000 pixels) already looks clean, which is enough for most photographs and digital art.
