Tile Calculator

Use this tile calculator to quickly estimate how many tiles you’ll need and what your project may cost before you order materials or start installation. Just enter the dimensions of the area you want to tile, the size of your tiles, and optionally the cost per box or per tile — and the tool will compute the total number of tiles needed, including an allowance for waste. This helps you avoid overbuying (which wastes money) and underbuying (which interrupts work), giving you confidence and accuracy as you plan your flooring, wall, or backsplash project.

Why Use a Tile Calculator?

Using a tile calculator helps make tiling projects more efficient and cost-effective by giving you an accurate estimate of tiles and material costs before you purchase or start installation. It reduces guesswork, minimizes waste, and ensures you have enough tiles to complete your layout — even when accounting for grout spacing, cuts, and complex patterns. Whether you’re tiling a small bathroom floor, an entire wall, or a large outdoor space, a tile calculator gives you the confidence to plan and budget effectively, helping avoid surprises and delays once work begins.

To use the tile calculator, start by entering the area measurements of the space you plan to tile, such as length and width in feet or meters. Then enter the tile size — typically in inches or centimeters — and your grout gap or waste percentage to accommodate cuts and pattern layouts. The calculator multiplies the surface area by tile dimensions and waste allowance to determine how many tiles you’ll need, and you can also include price per tile or per box so it can estimate total material cost. Because tiles are often sold in boxes, many calculators round up to the nearest full box to help you buy the right amount for your project.
