Three-panel (triptych) wall art: sizes and spacing
A 3-panel set should be about two-thirds of the furniture or wall section it hangs over, measured across all three panels, with 2–3 in (5–8 cm) between panels.
Triptych size chart
The total size is the three panels together; each panel is one third of the width. The overall width on the wall adds the two gaps.
| Total size | Total (cm) | Each panel | Overall with 2–3 in gaps |
|---|---|---|---|
| 36 × 24 in | 91 × 61 cm | 12 × 24 in | 40 – 42 in |
| 48 × 32 in | 122 × 81 cm | 16 × 32 in | 52 – 54 in |
| 60 × 40 in | 152 × 102 cm | 20 × 40 in | 64 – 66 in |
| 72 × 48 in | 183 × 122 cm | 24 × 48 in | 76 – 78 in |
| 96 × 64 in | 244 × 163 cm | 32 × 64 in | 100 – 102 in |
| 48 × 24 in | 122 × 61 cm | 16 × 24 in | 52 – 54 in |
| 72 × 36 in | 183 × 91 cm | 24 × 36 in | 76 – 78 in |
| 96 × 48 in | 244 × 122 cm | 32 × 48 in | 100 – 102 in |
| 60 × 20 in | 152 × 51 cm | 20 × 20 in | 64 – 66 in |
| 72 × 24 in | 183 × 61 cm | 24 × 24 in | 76 – 78 in |
| 84 × 28 in | 213 × 71 cm | 28 × 28 in | 88 – 90 in |
| 144 × 48 in | 366 × 122 cm | 48 × 48 in | 148 – 150 in |
Spacing between panels
- 2 in keeps the image reading as one picture — best when one photo is split across the panels.
- 3 in gives each panel a little air; more than about 4 in starts to break the image apart.
- Keep both gaps exactly equal — use a spacer block or a level with marks.
Which panel layout fits
Wide images (2:1 and 3:1) split naturally into three tall panels; a 3:2 image split in three gives panels close to 1:2. Square images rarely split well.
Hanging height
Treat the set as one piece: center it at 57–60 in, or keep 8–10 in above a sofa. Hang the middle panel first, then the outer two using the gap spacer. More in how high to hang art.

Questions
How far apart should 3-panel art be?
About 2–3 in (5–8 cm) between panels; 2 in keeps a split image reading as one picture.
How big should a triptych be over a sofa?
About two-thirds of the sofa width across all three panels — around 56–60 in total for an 84 in sofa.
How do I hang a triptych evenly?
Hang the middle panel first at the right height, then use a spacer block of the gap width to place the outer panels.
