How to calculate flooring by hand
Square feet to buy = Length × Width × (1 + waste) · Cartons = ft² ÷ carton coverage
Worked example
- Area: 12 ft × 14 ft = 168 ft².
- Waste 10%: 168 × 1.10 = 185 ft² to buy.
- Cartons at 20 ft²: 185 ÷ 20 = 9.2 → 10 cartons (check your product’s carton size).
- Underlayment: 2 rolls of 100 ft² if the flooring does not have it attached.
- Laminate carton
- 18–24 ft²
- LVP carton
- 20–24 ft²
- Hardwood bundle
- ≈ 20 ft²
- Waste: straight · diagonal · herringbone
- 10% · 15% · 20%
Questions crews ask
How much flooring do I need?
Room length × width in feet, plus 10% for cuts: a 12 × 14 room is 168 ft², buy 185. Divide by the carton size on the box (usually 18–24 ft²) and round up. For L-shaped rooms, split into rectangles and add.
How much extra flooring should I order?
10% for a straight layout in a rectangular room, 15% for diagonal, rooms with many jogs, or wide planks that cannot be end-matched as easily, and 20% for herringbone. Keep a carton for future repairs.
How many boxes of laminate for a 12x12 room?
144 ft² plus 10% is 159 ft². At 20 ft² per carton that is 8 boxes; at 24 ft² it is 7. Always round up, and check the carton coverage on the specific product.
