Over the headboard
Above a bed the rules shift: the headboard sets the line, the group should be a little narrower than the bed, and lighter frames are safer over a pillow. A row or a low, wide salon cluster usually works better than a tall grid. Two-nail frames stay level, which matters when you can't see them from your pillow.
Questions
How high should I hang a gallery wall?
With nothing under it, put the centre of the whole group about 145 cm (57 in) from the floor, the eye-level rule galleries use. Above a sofa, bed or sideboard, keep the bottom edge about 15 to 25 cm (6 to 10 in) above the furniture instead, so the art and the furniture read as one.
How far apart should the frames be?
5 to 8 cm (2 to 3 in) between frames keeps a group together. Tighter looks like a salon hang, wider looks calmer. Keep the gap the same everywhere; Salon packs the frames with exactly the gap you set.
How wide should a gallery wall over a sofa be?
About two thirds to three quarters of the sofa's width. On a 210 cm sofa that's roughly 140 to 160 cm across the group.
What is the hanger drop?
The distance from the top of the frame down to where it actually rests on the nail: the sawtooth hanger, the D-ring, or the wire pulled tight towards the top. Measure it on the back of each frame; it's usually 2 to 8 cm.
My frame has two D-rings. Where do the nails go?
Choose two hooks for that frame and enter the distance between the rings. Salon gives both nail positions at the same height.
Do I need to measure from the corner of the wall?
Every position is from the left edge of the wall and up from the floor. If your wall has no clean edge, switch to measuring from the centre line of the wall or the sofa.
