How it works
- Net area = Σ Length × Width; Area including allowance = Net area × (1+Waste or settling allowance (%)/100); Whole packs = ceil(Area including allowance/Coverage per pack)
- Worked example: 20 m² × 1.1 = 22 m²; ceil(22/2.5) = 9 Whole packs ⇒ 22.5 m²
- Supported input limits: Entries: 1–20; Waste or settling allowance (%): 0 ≤ x ≤ 1000; Coverage per pack: 1e-12 ≤ x ≤ 1000000000000; Price per pack (zero to omit): 0 ≤ x ≤ 1000000000000
Assumptions and limitations
Enter measured dimensions in the selected length unit; area, opening and pack coverage values use m². Allowances apply once and only purchases round upward. This estimates material quantities, not structural design, cutting layouts or installation standards. Product coverage and yields must come from your actual product.
