Inputs and units
Use the units shown beside each field. Replace the sample values with your measurements and the figures on the selected product packaging.
| Parameter | Example input |
|---|---|
| Length | 4 m |
| Width | 3 m |
| Product consumption | 4 kg/m² |
| Bag weight | 25 kg |
| Waste allowance | 10 % |
Formula and assumptions
Material massLength × Width × Product consumption × (1 + Waste allowance / 100)
Bagsceil(Material mass / Bag weight)
ceil = round up; floor = round down; max = the greater value. Trigonometric angles are converted from degrees to radians.
Allowance is applied before rounding to whole packages. Whole units are rounded up; displayed decimals are rounded only for readability.
Coverage depends on the product, substrate and installation method. Enter the supplier’s consumption figures; an area estimate cannot replace a cutting layout.
Worked example
Sample values are examples, not product specifications. Run the calculation again with your own measurements.
| Result | Calculation |
|---|---|
| Area | 12 m² |
| Material mass | 52.8 kg |
| Bags | 3 |
