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
