|---|---|
| Tile | tiles = area ÷ ((tile length + joint) × (tile width + joint)) |
| Area | Rectangle A = l × w · Triangle A = ½bh · Circle A = πr² |
| Hardwood Flooring | boards = area × (1 + waste) ÷ board area |
| Laminate Flooring | packs = area × (1 + waste) ÷ pack coverage |
| Vinyl Flooring | sheet: runs = room width ÷ roll width, then × room length |
| Carpet | linear metres = ceil(room width ÷ roll width) × room length |
| Tile Waste | tiles to buy = needed × (1 + layout waste + complexity) + spares |
| Grout | kg/m² = (L + W) ÷ (L × W) × joint × thickness × 1.6 |
