eng.tile-flooring-area Calculator
Calculates floor tile quantity, adhesive, and grout from room dimensions, tile size, and waste percentage. 10% waste is standard for straight-lay tile; 15% for diagonal patterns and rooms with many cuts — complex mosaics may require 20% waste allowance.
Inputs
Room Length M
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Room Width M
Horizontal extent perpendicular to the length.
Tile Length Mm
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Tile Width Mm
Horizontal extent perpendicular to the length.
Grout Gap Mm
Reference formula or conversion factor shown for context.
Waste Pct
A multiplier applied in the calculation.
Results
tiles needed
Sample size or count used in the calculation.
area with waste (m²)
The computed two-dimensional surface area.
tile area each (m²)
The computed two-dimensional surface area.
room area (m²)
The computed two-dimensional surface area.
without waste
Reference formula or conversion factor shown for context.
waste factor
A dimensionless multiplier applied in the calculation.
