Tile Calculator
Tile Calculator. Use the actual product label and your measured quantities. Starting values are editable examples, not universal rates or product specifications. Keep the units beside each input.
Method and practical checks
- Extra material covers cuts and breakage; complex patterns need an allowance chosen for that layout. Keep matching spare tiles.

Your measurements and assumptions

| Measured area | 12 | m² |
|---|---|---|
| Tile length | 60 | cm |
| Tile width | 30 | cm |
| Extra allowance | 10 | % |
| Pack size | 1.44 | m² |
Method and assumptions
extra_area = area * waste/100; buy_area = area + extra_area
Calculate gross area with waste, then round tile pieces and product packs separately. Pack area is taken from the manufacturer, not inferred from a nominal tile size.
Extra material covers cuts and breakage; complex patterns need an allowance chosen for that layout. Keep matching spare tiles.
Example with the selected inputs
- Measured area: 12 m²
- Tiles including allowance: 74
- Required quantity: 13.2 m²
- Packs to buy: 10
- Purchase quantity: 14.4 m²
- Left over: 1.2 m²
Change the inputs to match your own task. Whole packages are rounded up after allowances, so purchase quantity and actual requirement can differ. Apply each allowance once.
