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.
Example Calculation
A 12 ft by 10 ft bathroom floor with 12×12 inch tiles and 10% waste.
- 01Floor area = 12 × 10 = 120 sq ft
- 02Tile area = 12 × 12 / 144 = 1.00 sq ft per tile
- 03Tiles needed = 120 / 1.00 = 120 tiles
- 04With 10% waste = 120 × 1.10 = 132 tiles
