What this calculator estimates
This tile calculator starts from the measurements and options you enter, then estimates material quantity, waste, cost ranges, labor ranges, and a starter shopping list.
Results adapt to the selected region and unit settings, so the estimate is not locked to one market or measurement system.
Report confusing results, missing options, or assumptions that look off.
How this is calculated
- Net tile area is length x width x number of areas.
- Order area adds the selected waste percentage.
- Tile count divides order area by the selected nominal tile size.

Common mistakes
- Buying exact square footage with no waste for cuts or attic stock.
- Forgetting thinset, grout, spacers, trim, backer board, and sealer.
- Ignoring substrate prep, waterproofing, and layout complexity.
FAQ
How much extra tile should you buy?
Most simple layouts use about 10% to 12% waste. Diagonal patterns and small cuts often need more.
Does this work for backsplashes?
Yes for rough quantity planning, but trim pieces and outlet cuts need extra attention.
Why enter box coverage?
Tile is sold by carton, so box coverage lets the calculator estimate a realistic purchase count.
Can this tile calculator estimate cost by region?
Yes. The calculator uses the selected region and unit settings to adapt quantities, cost ranges, labor ranges, and assumptions.
How should you use the result before buying materials?
Use the result as a planning estimate, then compare it with a current supplier cart, contractor quote, or local project conditions before committing.
Limitations
This calculator does not include waterproofing design, substrate repair, demolition, heated floors, stairs, niches, or specialty trim.
This estimate is for planning only. It is not a contractor quote, engineering advice, or permit review.
Next step
Measure once more, compare the result with a real quote or shopping cart, and review the assumptions before buying materials.
