What this means
Flooring is sold by the pack, each covering a set area printed on the box. We divide your room area by that coverage and add waste for the offcuts created as you trim planks to fit walls and stagger the joints. Since you can only buy whole packs, the total is always rounded up.
Recommendations
- Allow ~8% waste for a rectangular room, more for diagonal laying or angled/irregular rooms.
- Buy an extra pack if the room is complex — returning an unopened pack is easier than sourcing a matching one later.
- Let laminate and wood acclimatise in the room for 48 hours before fitting.
Watch out
- Pack coverage varies a lot between products — always use the figure on your chosen flooring's packaging.
