💡 Tiling Tips
- • Always add 10% extra for breakage and mistakes
- • Diagonal/mosaic patterns require 15-20% extra
- • Buy tiles from same batch for color consistency
- • Account for grout lines in calculations
- • Use spacers for even grout lines
- • Larger tiles look better in small spaces
Formula
Area = Length × Width
Tile Area = Tile Length × Tile Width
Tiles Needed = Area ÷ Tile Area × (1 + Waste%)
How it works
Area = Length × Width Tile Area = Tile Length × Tile Width Tiles Needed = Area ÷ Tile Area Total with Waste = Tiles Needed × (1 + Waste %) Example: Area: 10ft × 10ft = 100 sq ft Tile: 12in × 12in = 1 sq ft per tile Tiles = 100 ÷ 1 = 100 tiles With 10% waste = 110 tiles
The tile calculator determines how many tiles you need for your project. Enter the area dimensions and tile size to get accurate estimates. Includes common tile sizes, waste factors for different layout patterns, and helpful tips.
Why this matters
Calculating tile needs prevents under-ordering (incomplete projects) and over-ordering (wasted money). Account for waste due to cutting, breakage, and layout adjustments. Essential for bathrooms, kitchens, floors, and any tiling project.
