Tiles and Flooring Estimator with Waste Margin
Count number of square or rectangular tiles needed for a flooring or walling layout. Surfaces divided by unit tile sizes, adding standard offsets for borders and fractures. CalcTracker provides this free online calculator for instant, precise, and detailed computations without requiring any sign-up or software installation.

Tile Area Formula
Required Tiles = (Room Area / Unit Tile Area) * (1 + Safety % / 100)
Room surface divided by tile footprint, adding a fractional waste buffer (typically 10%).
Example
- A 20m² terrace utilizing 30x30cm tiles with 10% offset requires exactly 245 modules.
⚠ Note
- Failing to add buffer leaves you short when tiling perimeter corners and cuts.
