Measure before you buy
Use finished project dimensions for tile rather than room names or rough estimates. Small dimension errors compound across larger surfaces.

Tile Calculator
Estimate tile area and tile quantity including grout gap and waste assumptions.
Enter your project measurements
Use measured dimensions, quantities, prices, and coverage rates for the project. The tile tool turns those inputs into a material, area, volume, or cost estimate.
Important: Use the inputs that match your situation. Results are estimates based on the values and assumptions entered.

Guidance
Include a realistic waste allowance
Cuts, breakage, pattern matching, damaged material, and packaging sizes can increase the quantity purchased beyond the exact mathematical amount.
Compare material units consistently
Convert feet, inches, square feet, cubic feet, yards, bags, boxes, or rolls consistently before comparing supplier prices or coverage claims.
Understand this calculator
How to use it
Start with the values requested by the Tile tool and replace any sample numbers with figures from your actual situation. Estimate tile area and tile quantity including grout gap and waste assumptions. Keep every entry in the unit and time period shown beside the field, then review the highlighted result together with the supporting outputs.
What the results mean
The highlighted result is the main answer produced by the Tile calculation. The additional result cards provide context, components, ratios, costs, quantities, or comparison values that help explain why the primary result changed when you adjusted an input.
How the calculation works
The Tile tool applies the arithmetic or modeling relationship described by the requested inputs and supporting outputs. Estimate tile area and tile quantity including grout gap and waste assumptions. Keep units, rates, and time periods consistent so the result reflects the scenario you intended to model.
Example and practical context
Use your current tile numbers as the baseline, record the result, then change one meaningful assumption and recalculate. For example, changing a price, rate, measurement, quantity, timeline, or cost while keeping the other inputs fixed shows how sensitive the outcome is to that one variable.
Results are estimates based on the values and assumptions entered. Review the Methodology and Calculator Disclaimer for important limitations.
