Gallery Wall Spacing: Plan an Even Grid of Picture Frames
Plan an even gallery-wall grid from outer frame sizes, gaps and margins. A worked six-frame example distinguishes frame positions from hanger points.
A useful starting point
Measure frame exteriors, choose either fixed gaps or symmetric margins and calculate the complete arrangement before marking the wall. The tool covers equal-size frames in a regular grid; hook positions and fixing choices remain separate.
A regular gallery wall is easier to plan when you measure the outside of each frame, not the photograph opening. Equal frame sizes and consistent gaps make the geometry predictable.
Frameology's spacing guide and layout examples offer visual planning context. Treat styling recommendations as choices for your room, not compulsory dimensions.
Choose the wall area and frame exterior
Measure the rectangle available for the arrangement, excluding furniture, switches or other constraints as appropriate. Record frame outer width and height in a consistent orientation.
Do not substitute an A4 image size for its frame's exterior. Where inches and centimetres are mixed, use the NIST conversion reference.
Work a six-frame layout
Assume a 2 m-wide, 1.4 m-high planning rectangle. Place three columns and two rows of frames, each 0.3 m wide and 0.4 m high, with chosen 0.06 m gaps.
| Quantity | Calculation | Result |
|---|---|---|
| Arrangement width | 3 × 0.3 + 2 × 0.06 | 1.02 m |
| Arrangement height | 2 × 0.4 + 0.06 | 0.86 m |
| Equal side margins | (2 − 1.02) ÷ 2 | 0.49 m |
| Equal top/bottom margins | (1.4 − 0.86) ÷ 2 | 0.27 m |
From the planning rectangle's upper-left corner, frame left edges are at 0.49, 0.85 and 1.21 m. Top edges are at 0.27 and 0.73 m.
Try the example in the gallery-wall spacing calculator. These coordinates locate frame corners, not nails or hooks.
Understand the alternative margin mode
You can instead fix symmetric margins and let the tool calculate gaps. In the same rectangle, choosing 0.2 m margins on all sides leaves horizontal gaps of 0.35 m and a vertical gap of 0.2 m.
That is a much looser composition than 0.06 m gaps. Do not enter both ideas mentally and expect them to produce the same layout. Compare the total arrangement before choosing.
Transfer the layout carefully
Use full-size paper templates or a measured mock-up. Confirm the relationship with the furniture below and the actual viewing height. Measure each frame's hanger offset separately and select suitable fixings for the wall and load.
The calculator does not select anchors, assess concealed services or model mixed-size salon arrangements.
Common questions
What if the tool says the arrangement does not fit?
Reduce frame count or size, change orientation where appropriate, or choose different gaps/margins. A negative gap or margin is not a valid hanging plan.
Can unequal frames use the same grid?
Only if their outer dimensions genuinely match the model. Otherwise make a custom plan. Coordinate the wall with the shelf layout or the room's rug and seating arrangement rather than measuring each decoration in isolation.
