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.

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.
