How The Calculation Works

Formulas, material coverage assumptions, waste buffers, and rounding standards.

Total square footage is calculated by multiplying room length by width.

The area of a single tile is computed in square inches (or cm) and converted to square feet (or meters).

Industry-standard waste buffer is applied depending on layout pattern: 10% for straight grid, 15% for diagonal, and 20% for herringbone.

Standard Formula: Tiles Needed = ⌈(Total Area / Single Tile Area) × (1 + Waste%)⌉
