How it is calculated
Packs = length × width × (1 + waste ÷ 100) ÷ pack coverage, rounded up. Skirting pieces = (2 × (length + width) − door widths) ÷ piece length, rounded up.
Example
Inputs: Room length = 5 m, Room width = 4 m, Pack coverage = 2.2 m², Waste allowance = 10 %, Total door width = 0.9 m. Result: Packs needed: 10; Floor area: 20 m²; Area covered by the packs: 22 m².
Limits and caveats
- Assumes a rectangular room; split an L-shaped room into two rectangles and add the results.
- Herringbone laying needs 15% waste or more.
Questions about this tool
How many packs for a 5 × 4 m room?
The floor is 20 m². With 10% waste and 2.2 m² per pack you need 10 packs.
Where do I find the pack coverage?
It is printed on the pack in square metres, usually 1.5 to 2.5 m² depending on plank size and count.
Do I need skirting across doorways?
No, which is why the door width is taken off the perimeter before counting pieces.
