Wall art hanging height and gallery wall calculator.
Enter the frame size, how many across and down, and the gap. The calculator centres the group 57 in off the floor (or a set distance above your sofa), then gives the top and bottom of the group, each frame's left edge from the wall corner and the nail height from your hanger drop. Inches or centimetres. Runs in your browser; nothing is sent or stored.

Worked example
Three 11 x 14 in frames side by side with a 3 in gap, centred at 57 in, over an 84 in (7 ft) sofa, with a 4 in hanger drop. Group width = 3 x 11 + 2 x 3 = 39 in; height 14 in. Bottom = 57 - 7 = 50 in, top = 57 + 7 = 64 in. Start 84 / 2 - 39 / 2 = 22.5 in from the left end; frame left edges at 22.5, 36.5 and 50.5 in. Nail height = 64 - 4 = 60 in. Above a 34 in high console instead, one 11 x 14 in frame with a 7 in gap has its bottom at 41 in and its top at 55 in.
Method
Plain arithmetic. A single picture is hung so its centre is 57 in off the floor, which means its top edge is 57 + half the frame height (the Hunker formula). For a grid of equal frames the whole group is treated as one piece and its centre is placed at the same height (Passion4Art and Chairish describe it this way; Hunker instead centres the largest piece at 57 in). Group width = frames across x frame width + gaps, and likewise for height. Frame left edges are spaced by frame width + gap from a left start that centres the group on the width you enter. Nail height = frame top minus the hanger drop.
Rules of thumb, not standards. The 57 in centre, the gap ranges (2 to 3 in for small frames, 3 to 6 in otherwise) and the 6 to 8 in gap above a sofa or mantel (Chairish says 6 to 12 in above furniture) all come from decorating guides listed below. Seated rooms and high ceilings are common reasons to deviate. Use a level, check the hanger and wall anchors suit the weight, and tape the layout on the wall before drilling.
Rule of thumb, not a standard. These are design rules of thumb from published decorating guides, not building codes or standards. Treat the result as a starting point and tape it out in the room before you buy or drill. Results are shown in both imperial and metric. Conversions use 1 in = 2.54 cm and 1 ft = 0.3048 m.

Frequently asked questions
How high should I hang a picture on the wall?
Hunker gives the 57 in rule: the centre of the artwork sits 57 in above the floor, so the top edge is 57 plus half the artwork height. Chairish says 57 to 60 in, and Hunker notes 60 in or higher can suit very high ceilings. The calculator defaults to 57 in and lets you change it.
How far apart should frames be on a gallery wall?
Guides disagree: Hunker says 3 to 6 in, and Mixtiles says 2 to 3 in for small frames and 3 to 6 in for medium and large ones. Pick one gap and keep it constant across the group; the calculator defaults to 3 in.
How high above a sofa should I hang art?
Hunker says the bottom of the frame should be 6 to 8 in above a sofa or mantel, which can put the art above eye level. Chairish gives 6 to 12 in above furniture. The calculator uses 7 in by default.
Where do I put the nail?
The nail goes where the hanger will rest, which is the frame top minus the distance from the top edge to the hanger when the wire is pulled tight or the hook is in place. Enter that drop and the calculator subtracts it from each frame top.
Is the gallery wall centred on the whole group or the biggest frame?
This calculator centres the whole group, as Passion4Art and Chairish describe. Hunker suggests starting with the largest piece centred at 57 in and arranging the others around it. For equal frames both give the same result.
