Tile Calculator

Designed for homeowners, builders, and other trades, a tile calculator estimates the number of tiles required for a specific project. It does this by inputting the dimensions of the space and the size of the tile. This tile estimator helps refine the calculation by considering additional factors like waste, cuts, and pattern layouts. A tiling calculator ensures you purchase the correct amount of tiles, minimising excess 
or shortage.

Simply measure the height and width of your space, ensuring you account for grout lines, and input these dimensions into the square metre tile calculator. It will automatically estimate the number of tiles required for your project. Please ensure you double-check your measurements. We recommend adding
a 10-15% surplus of tiles to account for any cuts, breakages, mistakes, or future repairs. Please note: The figures provided by the tile calculator are estimates. Always consult a professional tradesperson before finalising the number of tiles for your project.

You can use a tile calculator for many types of tiles, especially standard square or rectangular ones. However, its accuracy might vary with irregularly shaped tiles, mosaic patterns, or tiles that require a unique layout. In these cases, you may need to adjust the calculations manually or add an extra margin to allow for cuts, waste, and installation nuances. Always double-check the specifics of your project to ensure you purchase the correct amount of tiles. 


To measure your space for tiling, multiply the length by the width to get the total area in square meters or feet. Always include extra for cuts, waste, and pattern alignment.

For irregular spaces, divide them into smaller sections, calculate each area separately, and add them together. Always allow a 10-15% surplus for cuts, waste, and pattern alignment.

Yes, you should account for grout lines when measuring for tiles, as they affect the overall layout and spacing. Grout lines create small gaps between tiles, slightly altering the total coverage area. Always factor them into your calculations to ensure a precise fit and prevent misalignment.

We always recommend having a 10-15% waste allowance for tiles to account for any cuts and 
breakages, mistakes, or future repairs that may occur.

When using various tile sizes in one space, divide the area into sections based on the layout. Measure each section separately, calculate the required tiles for each size, and account for grout lines and waste. A tiles calculator or layout plan helps ensure precise measurements and a balanced design.

Rounding up when ordering tiles ensures you have extra for cuts, mistakes, and future repairs. We recommend ordering 10–15% more than the calculated amount to account for any cuts, breakages, mistakes, or future repairs.

Yes, you can calculate tiles for outdoor spaces the same way for indoor spaces. Measure the length and width to determine the total area, then factor in grout lines, waste, and any pattern layout. For outdoor tiling, consider extra tiles for cuts, breakage, and future repairs due to anticipated weather exposure. Then, enter these figures into our square metre tile calculator.

If you don’t know the exact area size, measure it as accurately as possible by breaking it into smaller sections and adding up their total area. If unsure, round up your measurements to ensure you have enough tiles. We recommend using a professional tradesperson to help refine your calculations.

Many factors influence the cost of tiles per square meter. These include tile construction, size and thickness, design and finish, brand and quality, manufacturing process, installation costs, and location or availability.
