How this calculator works
It finds your room area, adds 10% for cuts and waste, then divides by the square footage each box of flooring covers (printed on the box label).
Worked example — a 12 ft × 10 ft room, 20 sq ft per box:
120 sq ft × 1.10 = 132 sq ft ÷ 20 = 7 boxes.
Buy from the same batch
Order all your flooring at once from the same lot number — colors and patterns can shift slightly between production runs.
Frequently asked questions
How much extra flooring should I buy?
10% for straight rooms, up to 15% for diagonal layouts or rooms with many angles.
How many square feet are in a box of laminate?
It varies — commonly 16–24 sq ft. Always check the box label and enter that figure.
Planning a flooring or tile project
Buy the material for one room from the same product batch when possible. Layout, pattern direction, damaged pieces, and cuts around doors or cabinets affect waste, so a simple rectangular calculation is a starting point rather than a cutting plan.
How to use this estimate
- Measure the project in the units shown and recheck your measurements before ordering.
- Use the waste allowance as a planning buffer, not as a substitute for a detailed material takeoff.
- Compare the result with the package yield, coverage, or weight listed by your supplier.
- Prices are user-entered estimates and may change by location, product, delivery, and season.
