About ProTileCalc
Professional-grade tile calculators built on industry standards.
The Problem
Most tile calculators online are either too simple (ignoring critical waste factors) or hidden behind manufacturer paywalls. Finding accurate grout consumption formulas or thinset coverage rates usually involves digging through massive PDF handbooks.
Our Solution
ProTileCalc is a collection of free, transparent, and accurate calculators for the tile trade and serious DIYers. We don't just spit out a number—we show you the exact math and formulas used so you can verify the results yourself.
- Data-driven: Our formulas are based on the Tile Council of North America (TCNA) Handbook and manufacturer specifications.
- Pattern-aware: We build in pattern-specific waste factors (like 15% for herringbone) automatically.
- Comprehensive: From simple square footage to complex multi-wall shower enclosures.
