When planning a tiling project, whether it's for your floor, wall, or backsplash, it's essential to know how many tiles you will need. This process, known as a quantity takeoff, involves calculating the total number of tiles required to cover a specific area. In this guide, we'll walk you through the calculation, complete with an example, and provide a handy calculator to simplify the process.

## Understanding the Calculation

To determine the number of tiles required, you need to know:

**Total Area to be Tiled (in square meters or square feet):**The total area of the surface that you plan to cover with tiles.**Size of a Single Tile (in square meters or square feet):**The area that one tile will cover.**Wastage Percentage:**An allowance for tiles that may be cut, broken, or otherwise wasted during installation. A typical wastage percentage is 10%.

The formula to calculate the number of tiles needed is:

`Total Number of Tiles = (Total Area to be Tiled / Area of One Tile) * (1 + Wastage Percentage / 100)`

## Example Calculation

Let’s consider an example where:

**Total Area to be Tiled:**20 square meters**Size of a Single Tile:**0.25 square meters (0.5m x 0.5m)**Wastage Percentage:**10%

Using the formula:

```
Number of Tiles without Wastage = 20 sqm / 0.25 sqm/tile = 80 tiles
Total Number of Tiles = 80 * (1 + 10/100) = 80 * 1.1 = 88 tiles
```

So, you will need 88 tiles in total, considering a 10% wastage.
