How the tile calculator works
Estimate tile count and full boxes from surface size, tile dimensions, waste, and package size. RenoMetric separates measured geometry from planning assumptions such as waste, coverage, density, packaging, or spacing. That makes the output easier to audit and change.
Worked planning example
A 12 × 10 ft surface using 12 × 12 in tiles starts with 120 tiles before waste and box rounding.
Before you buy: measure the real project, use the exact product specifications where possible, and confirm final quantities with the supplier or installer. This tool is for estimating, not structural design, code approval, or a professional quotation.
Why the purchase number may be higher
Projects rarely purchase the exact geometric amount. Materials may need cutting allowance, breakage allowance, full-box rounding, full-bag rounding, or a project-specific reserve. RenoMetric shows these steps instead of silently building them into one unexplained number.
Tile Calculator FAQ
How much tile waste should I add?
Use the measurements and product values from your actual project. RenoMetric keeps the important assumptions visible so you can adjust them instead of relying on a hidden default.
Why does the calculator round up to boxes?
The result is a planning estimate, not a product guarantee. Coverage, yield, breakage, site conditions, and installation methods can change the final quantity.
Can I use this for wall tile?
Yes, when the geometry matches the calculator. For unusual shapes, split the project into simple measured sections and add the results.
