Start with the wall, not the artwork

Size anxiety usually comes from guessing. Remove the guess with two numbers. First, measure the wall space you want to fill. Second, apply the two thirds rule. A print hung above a sofa or console should span about two thirds to three quarters of that furniture's width. A standard 84 inch sofa wants something in the 56 to 63 inch range, which a 30x45 landscape approaches when oriented horizontally.

On a bare wall with no furniture beneath it, the print should occupy roughly the central half of the visible wall. A 24x36 inch piece handles most apartment living rooms. Anything under 16x20 inches on a large blank wall will read as an afterthought, which is the most common mistake and the easiest one to avoid.

What each size does in the room

Brown's landscapes, with their broad skies and open ground, reward horizontal formats. A wide print pulls a low ceilinged room outward and suits the composition better than a tall crop would. A 24x36 is the workhorse. Large enough to hold a seating area together, small enough that it does not dominate a modest room.

Go larger, 30x45 or more, when the sofa is long or the wall runs past ten feet. Go smaller, 18x24, for a wall interrupted by a doorway, a lamp or shelving. A framed print adds two to five inches per side depending on the moulding, so measure the framed dimensions, not the paper size, before committing.

Before you order, check these

Hang height matters as much as width. Centre the print about 57 inches from the floor, the gallery standard, or align its lower edge six to eight inches above a sofa back. Tape a paper rectangle of the exact size to the wall and live with it for a day. It costs nothing and settles most doubts in an afternoon.

Also check the light. A print opposite a window will throw glare at certain hours regardless of size. And consider the room's other art. One large Brown landscape beats a cluster of small ones in most living rooms, because his compositions carry open space and read poorly when crowded.
