How this calculator works
This calculator divides finished floor area plus a visible cut allowance by the coverage stated on the selected tile package.
- Measure finished floor length and width.
- Use the coverage printed on the selected tile package.
- Increase allowance for diagonal layouts, complex cuts or extra repair stock.
Worked example: Example: a 12 ft × 10 ft floor is 120 ft². With 10% waste and 12 ft² per package, it rounds to 11 packages.
Assumptions and limitations
- Coverage should use the selected manufacturer's product label or quoted net coverage.
- Waste is added before whole-unit purchase rounding.
- Complex layouts, seams or patterns can require a higher documented allowance.
Common mistakes to avoid
- Confirm the measurement basis and units before using the result.
- Keep waste or allowance visible and adjust it for the actual job conditions.
- Confirm supplier packaging, delivery increments, specifications, and final site requirements before ordering.
