How to Calculate Tiles Needed
Formula
Tile calculations must account for the tile size, grout spacing, waste from cuts, and breakage. A 10% waste factor is standard for straight layouts.
Each tile covers its area in square feet: a 12×12 inch tile covers 1 sq ft, while a 24×24 tile covers 4 sq ft.
Common use cases:
- Bathroom floor tiling
- Kitchen backsplash
- Shower wall tiling
