A sofa gives a gallery wall a natural starting point. Instead of centring a picture on the entire wall, first consider the furniture grouping: sofa, side tables and any nearby shelves. The arrangement should feel connected when you sit down as well as when you enter the room.
Measure the whole group
For two or more prints, measure from the outside edge of the first frame to the outside edge of the last. Include the gaps. Individual posters may look modest on their own but create a wide arrangement together.
Try three layouts on paper
A single large print creates a clear focal point. A pair gives a calm, balanced result. A mixed gallery wall can feel more personal, but needs a shared colour, subject or frame finish. Tape paper templates to the wall to compare the options at full size.
Check the height from your seat
A layout that looks comfortable while standing can feel disconnected above a sofa. Sit in your usual place and look at the lower edge. Leave practical clearance above the backrest, and check that people leaning back will not touch the frames.
Keep the spaces consistent
Consistent gaps help different sizes feel like one arrangement. If a gap seems too large, the pictures may read as separate groups. Step back before changing the artwork itself: adjusting spacing often solves the balance.
