## How to Calculate Tiles Needed

### Formula

**Tiles = Floor Area / Tile Area × (1 + Waste %)**

Convert tile dimensions from inches to feet (divide by 12) to get tile area in sq ft, then divide the total floor area by the tile area. Add 10% waste for straight layouts and 15% for diagonal layouts.

Esempio Risolto

A 12 ft by 10 ft bathroom floor with 12×12 inch tiles and 10% waste.

  1. Floor area = 12 × 10 = 120 sq ft
  2. Tile area = 12 × 12 / 144 = 1.00 sq ft per tile
  3. Tiles needed = 120 / 1.00 = 120 tiles
  4. With 10% waste = 120 × 1.10 = 132 tiles
