Flooring
Laminate, linoleum, parquet board — how many packs.
Packs needed
9packs
Underlay: 21 m² · leftover ≈ 1.6 m²
How the figure is calculated20 m² + 5% (straight layout) = 21 m² ÷ 2.4 m² per pack = 9 packs. Buy 21.6 m² — leftover ≈ 1.6 m². Underlay: area + 5%.
Let laminate rest in the room for 2 days before laying — it adjusts to the humidity and will not buckle.
Sources and methodology
- Packs: area × (1 + reserve) ÷ pack area
- Roll width — by the room’s shorter side
