Calculates the number of drywall sheets required for walls or partitions.
The drywall (plasterboard) calculator works out how many sheets you need to clad walls or a ceiling, allowing for the number of layers and a cutting margin.
Sheets = ⌈area × layers / sheet area × (1 + waste / 100)⌉ Standard sheet: 1200 × 2500 mm = 3.0 m²
40 m² of walls, 1 layer, sheet 1.2 × 2.5 m, 10% waste. Sheets: ⌈40 × 1 / 3.0 × 1.1⌉ = ⌈14.67⌉ = 15 sheets.
