Classic tool
Tile Calculator
Calculate floor area, tile count, waste allowance and estimated boxes for flooring or wall tile.
Use this tile calculator to estimate how many tiles you need for a rectangular room or wall. Enter the space dimensions, the tile size and a waste margin for cuts, breakage and a practical spare.
How the calculation works
The room area is length × width. Tile area converts centimeters to meters, then divides the total area by the area of one tile. The result is rounded up and the waste percentage adds a realistic buffer for installation.
If the project has niches, irregular corners or multiple areas, calculate each section separately and add the totals before you buy.
Use clear inputs to get a more useful result.
How to use Tile Calculator
Open the tool, fill in the fields with the data you already have and generate the result step by step. If you want to compare scenarios, change one field at a time so it is easier to understand the impact of each value.
When Tile Calculator is useful
The goal here is simple: Calculate floor area, tile count, waste allowance and estimated boxes for flooring or wall tile. It works well for quick checks, planning, study and review before you move to a final decision or document.
What to review before using the result
Check units, labels, numbers, timing and any context that can change the meaning of the output. If the result will be used in a quote, technical task, published page or report, finish with a manual review.
Frequently asked questions
What should I prepare before using the tool?
Keep the key values, labels and units ready before filling in the fields. Cleaner inputs make the final result easier to review and compare.
Can I test different scenarios on the same page?
Yes. The safest approach is to change one field at a time, compare the outputs and note which value actually changes the final answer.
Is the result ready to use without checking it?
It is better to treat it as support. Review the output once more before using it in a quote, document, spreadsheet, technical task or published page.
