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 |
|---|---|
| Wall perimeter | 18 m |
| Total doorway width | 1.8 m |
| Stock piece length | 2.4 m |
| Waste allowance | 8 % |
Formula and assumptions
Linear lengthmax(0, Wall perimeter - Total doorway width) × (1 + Waste allowance / 100)
Whole piecesceil(Linear length / Stock piece length)
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.
