Quick answer
Estimate tile for kitchen floors and backsplashes using measured area, tile dimensions, cutting allowance and package size. Use the working RenoMetric calculator below for the actual estimate, then use this page to check assumptions, package rounding and project-specific considerations.

How to get a better estimate
Measure the actual project rather than relying on listing dimensions. For irregular spaces, split the surface into simple measurable sections and add the results. Use the exact product label for package coverage, yield, density or square-foot coverage whenever it is available.
Keep waste and package rounding as separate steps. Waste covers cuts, breakage, pattern matching and unavoidable offcuts. Package rounding reflects the fact that many materials are sold only in complete bags, boxes, bundles or cans.
Before you buy: this page is a planning guide, not a contractor quotation or structural design. Verify final quantities with the product manufacturer, supplier or installer when project conditions could materially change the result.
Kitchen Tile Calculator FAQ
How do I measure a backsplash?
Multiply the total backsplash length by its height, then subtract large non-tiled areas if useful.
Do outlets reduce the tile order much?
Usually not enough to rely on for savings. Small openings also create extra cutting and breakage.
Should I add more for patterned tile?
Often yes. Pattern matching and centered layouts can increase offcuts compared with a simple running layout.
