Where should I position D-rings on the frame?

D-rings should be positioned one-third of the way down from the top of the frame back. This ensures the frame hangs flush against the wall and slightly tilts forward at the top for better viewing angle.

What size D-ring do I need?

No. 1 (small) for frames up to 4 kg, No. 2 (medium) up to 10 kg, No. 3 (large) up to 20 kg. For very heavy frames, use strap hangers or split battens instead of D-rings.

Should I use one or two D-rings?

Always use two D-rings — one on each side, at the same height. This distributes weight evenly and keeps the frame level. Single-point hanging (one D-ring at centre top) is only for very light frames.

What screws should I use?

Use pan-head screws that are shorter than the frame moulding depth (to avoid poking through the front). 12 mm screws for small frames, 16-20 mm for larger frames. Pre-drill pilot holes to prevent splitting.

What wall hook should I use?

Picture pins work for frames under 5 kg on plasterboard. Hardwall hooks work on brick and plaster. For heavy frames (over 5 kg), use wall plugs and screws into masonry or locate a wooden stud.

How D-Ring Placement Works

D-ring position = Frame height / 3 from top

The one-third rule ensures the centre of gravity is above the hanging point, keeping the frame flush against the wall. D-ring size is determined by total frame weight. Screw length should not exceed moulding depth.
