How to hang a heavy canvas
For a heavy canvas, a French cleat is the method both sources point to: two strips with opposing 45 degree bevels, one fixed into wall studs and one on the back of the piece, so gravity locks them together. CustomPictureFrames recommends cleats above 25 lb and for canvas and oversized frames, and This Old House says one person can hang a heavy piece with them.

Steps
- Weigh the piece. Choose hardware rated for at least 1.5 times the total weight of frame, glass, mat, backing and artwork (CPFH).
- Rip a 45 degree bevel into a strip of three-quarter inch plywood or a 1 by 6 and cut it in two so the bevels oppose (This Old House).
- Screw the wall strip into studs with the lip up and away from the wall, keeping it level. Check the manufacturer's rating on the screws and anchors; CustomPictureFrames says heavy frames need studs or heavy-duty anchors.
- Attach the other strip to the piece with its lip facing down, using fixings rated for the piece (check the manufacturer's rating on the pack).
- Lift the piece so the bevels interlock. Make the wall strip slightly shorter than the piece to allow side-to-side adjustment (Wikipedia).
Which hardware for which weight
| Weight band | Suggested hardware and source |
|---|---|
| Under 10 lb | Any hanging hardware works (CPFH) |
| 5 to 15 lb | D-rings with wire (CPFH) |
| 25 to 50 lb | Two-point hangers or heavy-duty D-rings with braided wire (CPFH) |
| Over 25 lb | French cleat, or D-rings driven into studs (CPFH); cleats suit canvas and oversized frames (CPFH) |
| Heavy items you may move later | French cleat (This Old House) |
CustomPictureFrames is not consistent with itself: its summary says cleats or stud-mounted D-rings for frames over 20 lb, while its body says over 25 lb. Treat 20 to 25 lb as the zone where you read the hardware pack and consider a cleat. See French cleat for the definition and hardware by weight for the comparison.
