Ultimate Tile & Grout Calculator – Precision Planning for Kitchens & Baths
Meta Description: Calculate exact tile counts and grout requirements for your next renovation. Supports multiple tile sizes, waste margins, and pattern planning. Fast, free, and accurate.
Introduction: The Geometry of Aesthetic Perfection
Tile is an unforgiving discipline. Unlike paint, where you can easily buy a spare quart, tiles are heavy, expensive to ship, and manufactured in specific "dye lots." If you fail to order correctly, the color variance between batches can ruin a professional finish. Precision math is the only defense against the dye-lot disaster.
Professional Material Auditing
Our tool translates abstract square footage into an actionable shopping list. We account for the "Nominal Gap" of grout joints and the "Pattern Waste" required for complex layouts like Herringbone or 45-degree Diagonal grids.
Tiling Excellence Standards
- The Batch Mandate: Kiln temperatures and mineral shifts mean even the same SKU can vary in color. Always order 10% more than the net area to ensure every tile comes from the same firing.
- Pattern Multipliers: A straight grid requires 10% waste. A diagonal "diamond" pattern requires 20% due to the massive number of triangular corner cuts that cannot be reused.
- Lippage Prevention: For large-format tiles (over 12x12), use a mechanical leveling system. This "pins" the corners during the 24-hour drying period, preventing trip hazards.
- Attic Stock: Never return your last half-box. Keep 10% of your project tiles in storage for future repairs—matching a dye lot five years later is impossible.

Frequently Asked Questions (FAQ)
Q: Sanded vs. Unsanded Grout?
A: Sanded grout is used for joints wider than 1/8" to provide structural strength. Unsanded grout is for thin joints or delicate glass tiles that might be scratched by sand particles.
Q: Can I tile over existing tile?
A: Only if the original base is perfectly bonded. However, "Total Rip-out" remains the professional recommendation to prevent height-clearance issues with doors.
Q: What is "Thin-set"?
A: It is the cement-based adhesive used to bond tile to the subfloor. It is designed to be applied in a 3/16" to 1/2" layer for maximum bond integrity.
