How picture wire is used
Picture wire runs between two D-rings so a frame hangs from one nail. Cut it about 12 inches longer than the gap between the rings, wrap the tail 3 to 4 times, and let the peak sit 2 to 3 inches below the top edge. Use the lower of the wire and hanger ratings.

Wire facts
| Point | Detail | Source |
|---|---|---|
| Length | About 12 in longer than the gap between the rings | CPFH |
| Finish | Leave about 2 in tail, loop back through the ring, wrap 3 to 4 times | CPFH |
| Sag | Wire peak 2 to 3 in below the top edge | CPFH |
| Rating | At least 1.5 times total weight (CPFH); use the lower of wire and hanger (PHS) | CPFH, PHS |
| Drawback | Frames can slide and tilt on a single wire | PHS |
| Foamboard | Not recommended: wire cuts through foam | PHS |
| Heavier items | The seller recommends cleats instead | PHS |
Nail height with the centre at 57 inches
Top edge = 57 + height / 2, and the nail sits at the wire peak, so nail height = top edge minus the sag (2 to 3 in). Inches.
| Frame height (in) | Nail height, 2 in sag | Nail height, 3 in sag |
|---|---|---|
| 12 | 61 | 60 |
| 16 | 63 | 62 |
| 20 | 65 | 64 |
| 24 | 67 | 66 |
| 30 | 70 | 69 |
Example of the lower-rating rule: PHS says a 25 lb D-ring with a 100 lb wire gives a 25 lb limit. See D-ring.
