Verify the inputs
Measure or document each input. If a value is only an estimate, record its source and test a conservative alternative.
Construction/ CALCULATOR
Tile quantity and pack estimate
Estimate full tiles, order area and packs from the net surface, tile dimensions and a stated cutting allowance.
FROM ESTIMATE TO ACTION
Use the result, not just the number.
Keep the calculation traceable
Save the input link or copied result together with the date, units and assumptions. A number without its inputs cannot be checked later.
Confirm the decision
Compare the estimate with the related guide, current product data and requirements that apply at your location before buying or building.
Inputs to verify
- Measured tiled area (m²)
- Measure each surface receiving the same tile and layout.
- Excluded full-tile area (m²)
- Subtract only areas that receive no tile; small penetrations still create cuts.
- Tile length (mm)
- Use the nominal face dimension of one tile.
- Tile width (mm)
- Use the nominal face dimension of one tile.
- Cutting and breakage allowance (%)
- Choose from the actual layout complexity, not one universal percentage.
- Declared coverage per pack (m²/pack)
- Use the supplier label for the exact tile and batch.
