Why does frame weight matter?

Frame weight determines what hanging hardware you need and whether a wall can support it. Plasterboard walls with picture pins support up to about 5 kg. Heavier frames need wall plugs into masonry or screws into studs.

What is the heaviest component?

Glass is usually the heaviest component. Standard 2mm glass weighs about 2.5 kg per square metre. For a large frame (60 x 80 cm), glass alone weighs about 1.2 kg. Switching to acrylic saves approximately 50% weight.

How can I reduce frame weight?

Use acrylic glazing instead of glass (50% lighter). Choose aluminium moulding (40% lighter than wood). Use foam board backing instead of MDF. These changes can reduce total weight by 30-50%.

What is the weight limit for picture hooks?

Single picture pins: ~2 kg. Double picture pins: ~4 kg. Hardwall hooks: ~5 kg. Heavy-duty hooks with wall plugs: ~15 kg. For anything heavier, use expanding bolts or find a wall stud.

Should I weigh the frame or estimate?

For hanging hardware selection, estimation is fine. This calculator provides a conservative estimate. If you need exact weight (for shipping or insurance), weigh the completed frame on bathroom scales.

How Frame Weight Estimation Works

Total = Frame + Glass + Backing + Mat + Artwork

Frame weight is estimated from moulding perimeter, width and material density. Glass, backing, mat and artwork weights are calculated from the glazing area and standard material densities.
