Tile Calculator

Calculate exact tile quantities from area dimensions and tile size. Includes grout joint spacing in the effective tile module and rounds up to whole boxes for accurate ordering. Formula: Tiles = (Area ÷ Effective Tile Area) × (1 + Waste%).

Automatically applies the correct waste factor for your layout: 10% for straight grid, 15% for diagonal, and 20% for herringbone or complex patterns. Reduces costly second trips and mismatched dye lots.

Estimate thinset by trowel notch size (1/4"×1/4" covers ~80 sq ft per 50 lb bag; 1/4"×3/8" covers ~60 sq ft) and grout by joint width and tile thickness. Includes waste allowance for mixing and application losses.

Calculate tile spacers needed based on tile count and joint layout. Estimate trim pieces for exposed edges and perimeter, with trim length and piece count. Ensures every accessory is on the order.

Get detailed cost projections for tiles, thinset, grout, spacers, and trim. Adjust unit prices to match local market rates — typical tile material costs range from $1–$25 per sq ft depending on type.

Work in feet, inches, yards, meters, and centimeters. Tile sizes can be entered in inches or millimeters. All calculations, material counts, and cost estimates update automatically. Fully functional offline with no internet required.
