How to size and hang a gallery wall above a sofa
Over a sofa, the art and the furniture should read as one unit. Two numbers do most of the work: width and the gap above the back.
- Width: about two-thirds of the sofa's width (up to three-quarters).
- Bottom edge 8–10 in (20–25 cm) above the sofa back.
- Center the group on the sofa, not on the wall.
- Keep the group's center near eye level where you can.
Width: about two-thirds of the sofa
A group that's roughly two-thirds to three-quarters of the sofa's width looks anchored. Much narrower and it floats; as wide as the sofa and it looks heavy. Measure the sofa's full width, including the arms.
Height: 8–10 inches above the back
Leave about 8–10 in (20–25 cm) between the top of the sofa back and the bottom of the lowest frame. Closer and heads will bump the frames; much higher and the art disconnects from the sofa.
Center it on the sofa
If the sofa isn't centered on the wall, center the group on the sofa. That's the unit people see.
A worked example
Sofa: 84 in wide (213 cm), back 34 in high (86 cm), centered 70 in (178 cm) from the left wall.
Group width: 2/3 × 84 = 56 in (142 cm), up to 3/4 × 84 = 63 in (160 cm).
Bottom of the group: 34 + 9 = 43 in (109 cm) above the floor.
Group height: with a 30 in (76 cm) tall group, its center lands at 43 + 15 = 58 in (147 cm): right in the eye-level range.
Left edge of the group: 70 − 56 ÷ 2 = 42 in (107 cm) from the left wall.
From there, each frame's nail is its top-edge height minus its hanger's drop, and its horizontal position comes from the layout. See the full method.
Layouts that work over a sofa
- A row of three to five equal frames, center-aligned.
- Two rows (for example 2 × 3) with a shared center line.
- An anchor piece flanked by smaller frames, kept wider than it is tall.
Keep the overall shape wider than it is tall over a sofa; tall arrangements suit narrow walls and stairways better. More ideas in gallery wall layouts.
