Tile Calculator 2026

Calculation Result

For an area of 18 m² with tiles measuring 30 cm x 60 cm and considering a waste factor of 10%, you'll need approximately 13 tiles.

The total number of tiles calculated is 12.1, rounding up to 13. Adding a waste factor, this ensures you have enough tiles to cover any breakage or miscalculations during installation.

How the Calculator Works

Our tile calculator works by taking the total area you want to cover and dividing it by the area of a single tile. We then account for a waste percentage, which helps to cover any unforeseen issues during installation.

Simply enter the area size, tile dimensions, and waste percentage to get your results.

Example Calculation

Let's say you have a room that is 25 m² and you are using tiles that are 40 cm x 40 cm. First, calculate the area of one tile:

• Tile Area = 0.4 m x 0.4 m = 0.16 m²

Now divide the room area by the tile area:

• 25 m² / 0.16 m² = 156.25 tiles

With a 10% waste factor, you would round up to 172 tiles needed.

Extra Tips

When planning your tiling project, always measure twice to avoid errors. Consider the layout of the tiles and how they will fit in your space to minimize waste further.
