Waste

8%

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.

Pro tips

  • Measure the room at its widest points, and include doorways and alcoves you'll be flooring.
  • Keep one spare plank or two aside for repairs after installation.

Was this calculator useful?

Laminate, vinyl and engineered wood all come in packs that cover a fixed area. This calculator turns your room size into the number of packs to buy, with a sensible waste margin built in.

How the estimate works

Every pack states the area it covers. Dividing your floor area by that number gives the bare requirement; adding waste accounts for the offcuts from trimming planks at the walls and staggering the end joints for a natural look. The result is rounded up because you buy whole packs.

Getting the measurements right

Measure length and width at the widest points and include any doorways, bays or alcoves you'll floor. For L-shaped rooms, split the space into rectangles, calculate each, and add them together before applying waste.

Frequently asked questions

Divide your room's area by the coverage printed on each pack, then add about 8% for waste and round up to whole packs. This calculator does that automatically.

Around 8% for a simple rectangular room, and 10–15% if you're laying diagonally or the room has lots of angles, alcoves or doorways.

Flooring is only sold in complete packs, so any partial requirement means buying the next full pack. The leftovers double as spares for future repairs.
