What to enter
| Input | Meaning and units |
|---|---|
| Net area to cover (m²) | Area in square metres. Convert both dimensions consistently before multiplying them. |
| Usable coverage per purchased pack or sheet (m²/unit) | Enter usable coverage per purchased pack or sheet in m²/unit; use the same basis as the other measurements. |
| Cutting and waste allowance (%) | Enter percentage units: 5 means 5%, not a fraction of 0.05. |
Understanding your result
The answer estimates quantity, coverage or cost from the dimensions and allowances you entered. It does not size a structural member, assess capacity or determine installation adequacy.
Common mistakes
- Mixing centimetres with metres, or outside dimensions with the actual filled volume.
- Treating allowance, compaction, supplier yield and density as interchangeable adjustments.
Check your calculation
- Measure independently, subdivide irregular shapes, and compare supplier pack/yield information with the units used here.
