What does this page calculate?
The weight of an acrylic (PMMA, Plexiglass) sheet depends on its thickness and size. The tool calculates the weight per square metre (kg/m²), the weight of one sheet, the total order weight and how many people should carry it. Optionally it also shows the number of pallets and which vehicle carries the order in one trip. The page opens with a 3 mm, 125 × 205 cm sheet.
Step by step
- Unit weight: kg/m² = thickness (mm) × density (g/cm³). Acrylic density is about 1.19 g/cm³. The unit check is simple: 1 m² of a 1 mm sheet with a density of 1 g/cm³ weighs 1 kg.
- Sheet area: width (m) × length (m). A 125 × 205 cm sheet is 2.5625 m².
- Sheet weight: unit weight × area.
- Total: sheet weight × quantity.
- Carrying: one person up to 25 kg, two people up to 50 kg, a vacuum lifter or sheet trolley above that. Sheets with a long side of 3 m or more are carried by at least two people.
Acrylic weight by thickness
| Thickness | kg/m² | 125 × 205 cm | 205 × 305 cm |
|---|---|---|---|
| 2 mm | 2.38 | 6.10 kg | 14.88 kg |
| 3 mm | 3.57 | 9.15 kg | 22.32 kg |
| 5 mm | 5.95 | 15.25 kg | 37.20 kg |
| 8 mm | 9.52 | 24.40 kg | 59.52 kg |
| 10 mm | 11.90 | 30.49 kg | 74.40 kg |
Example: 3 mm acrylic, 125 × 205 cm
Unit weight 3 × 1.19 = 3.57 kg/m². Area 1.25 × 2.05 = 2.5625 m². One sheet weighs 3.57 × 2.5625 ≈ 9.15 kg and one person can carry it. Four sheets weigh about 36.6 kg in total. A 205 × 305 cm sheet of the same thickness is 22.3 kg; it stays under 25 kg, but the long side exceeds 3 m, so it should be carried by two people.
How to use the result
The calculation uses nominal thickness and density. The actual sheet thickness may differ by a few per cent within tolerance, and the protective film adds a little weight. Leave a margin when choosing support profiles, screws and anchors. For a job with offcuts, first find the number of sheets with the cutting calculator, then enter the quantity here. Add the result to the basket and request a quote; our branch will reply with price and stock.
