Variables Explained
| Input | What it means |
|---|---|
| Length of area (L) | The measured end-to-end distance of the section being calculated. |
| Width of area (W) | The crosswise measurement, perpendicular to the length. |
| Tile length (l) | The measured end-to-end distance of the section being calculated. |
| Tile width (w) | The crosswise measurement, perpendicular to the length. |
| Gap width (g) | The crosswise measurement, perpendicular to the length. |
| Waste factor | Use the measured or stated value for this item, with the unit or category shown beside the field. |

Worked Example
A 12 m² floor using 0.3 m × 0.3 m tiles needs about 134 tiles before joint and waste adjustments.

Why Use This Calculator?
Use the result to put measurements on a common basis before comparing them or estimating quantities. The original measurement precision still limits the precision of the answer.
7
Common Mistakes
- Tile joints and edge cuts affect the layout. Order enough matching-batch tiles for the actual pattern.

Frequently Asked Questions
When should I round a measurement?
Carry the measured values and conversion factors through the calculation first. Round the final result to a precision justified by the original measurements.
Why can a supplier’s quantity differ?
Measurement conventions, nominal sizes, density assumptions and purchase rounding can change a practical quantity. Compare the units and assumptions before comparing the numbers.
