How to Calculate Tiled Area Quantity Takeoff: A Step-by-Step Guide with Calculator
Prepared By: Parag Kamlakar Pal – Owner of www.civilnotess.com
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.
Tile Quantity Calculator
Use the calculator below to determine the number of tiles you will need for your project:
function calculateTiles() {
// Get input values
const area = parseFloat(document.getElementById(‘area’).value);
const tileSize = parseFloat(document.getElementById(’tileSize’).value);
const wastage = parseFloat(document.getElementById(‘wastage’).value);
// Calculate number of tiles needed
const numberOfTiles = area / tileSize;
const totalTilesWithWastage = numberOfTiles * (1 + wastage / 100);
// Display the result
document.getElementById(‘result’).innerHTML = `Total Number of Tiles: ${Math.ceil(totalTilesWithWastage)}`;
}
