Everything is computed in this tab — nothing is sent anywhere.

How many packs of laminate a floor needs — and how much stays in the last pack for future repairs. Waste is applied to the area before anything is rounded; packs are rounded once, because packs are what the shop sells.

Packs, not square metres

The box states its coverage — 2,22 m² is a common figure — and the shop sells whole boxes. So the honest computation runs: area, plus waste for the chosen lay, divided by the pack's coverage, rounded up once. Round anywhere earlier and phantom packs appear; skip the waste and the floor ends a row short on a Sunday evening.

The plank count is optional but handy at the door: a pack of eight 1 285 × 216 mm planks covers 2,22 m², and knowing you need 69 planks makes the last-row arithmetic — rip width, stagger, which wall to start from — something you can do standing in the room.

Frequently asked questions

Why keep the spare instead of returning a pack?

Because laminate is dyed in batches: the same article bought next year will not quite match. The leftover square metre from this batch is the only repair kit that exists for this floor — a swollen plank near the kitchen years from now is a ten-minute fix with it, and a whole-room argument without it.

How much waste does a diagonal lay really cost?

Around thirteen per cent against five for a straight lay. Every row that meets a wall at 45° loses a triangle at both ends, and the offcuts rarely reuse. In money it is usually one to two extra packs per room — worth knowing before falling for the look.

Should rooms be summed or calculated one by one?

One by one, if the lay direction changes at doorways or the rooms are separated by thresholds — the offcut from one room only helps the next when the planks run the same way. Sum them only for one continuous floor.

What about the expansion gap?

The 8–10 mm perimeter gap the floor needs to breathe hides under the skirting and costs no material worth counting: on a 4 × 5 m room it is under 0,2 m², already inside the waste allowance.
