Frame Weight Calculator — Total Framed Artwork Weight

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.

Glass is usually the heaviest component. Standard 2 mm soda-lime glass weighs about 5 kg per square metre (2.5 kg/m² for every 1 mm of thickness). For a 60 x 80 cm sheet (0.48 m²) the glass alone weighs about 2.4 kg. Switching to 2 mm acrylic (about 2.4 kg/m²) roughly halves that, saving around 50% of the glazing weight.

Use acrylic glazing instead of glass — at about 2.4 kg/m² it is roughly half the weight of 2 mm glass. Pick a slimmer or shallower moulding to cut the profile mass, and use foam board backing instead of MDF. A mat (window mount) adds 0.8 kg/m². Together these changes can reduce total weight by 30-50%.

Single picture pins: ~3 kg (LION framing supplies rate their standard single-pin hook at a 3 kg safe working load). Double picture pins: ~7 kg (retail ratings run to 10 kg; allow a margin). Hardwall hooks: ~5 kg on plasterboard. Heavy-duty hooks with wall plugs: ~15 kg. For anything heavier, use expanding bolts or find a wall stud. Always check the rating on the packet; capacities assume sound walls.

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.
