Your measurements
How it's worked out
Packs = area × (1 + waste) ÷ coverage per pack. Use about 7% waste for straight lay and 12–15% for diagonal or herringbone. Skirting = room perimeter − 0.82 m per doorway, bought in 5.4 m lengths.
Estimates only. Check sizes, coverage and quantities with your supplier, engineer or certifier before ordering. Standards references are a guide, not compliance advice.
