Tile Calculator

How the calculation works

Tile area = length × width/10,000 for centimeter dimensions. Tiles = surface area/tile area × (1 + waste/100), rounded up.

Inputs

• Surface area, m²
• Tile length, cm
• Tile width, cm
• Tiles per box
• Waste, %

Calculation details

For 12 m² with 30 × 30 cm tiles, 134 tiles are needed before waste. The purchase is rounded up to whole boxes.

This area estimate does not design a layout. Grout joints are not subtracted, making the estimate slightly conservative. Set an allowance appropriate for diagonal layouts or complex cuts.
