To use this tile calculator, you must first measure your wall or floor.

Wall Tile Calculator: How to Measure Your Walls

Step 1: Measure the length of the wall you want to tile. 

Step 2: Next, measure the height of the wall you want to tile 

Step 3: Do this for each wall in the room you want to tile. 

Floor Tile Calculator: How to Measure Your Floor

Step 1: measure the length of the floor area you want to tile. 

Step 2: Next, measure the width of the floor you want to tile. 

Calculating Tile Area in Square Metres

Once you have the values for your wall or floor, simply enter them into our tile calculator. The calculator will then work out the area to be tiled in square metres.

Tip: Square and rectangular pieces are easy to measure, but L-shaped pieces can be a little tricky to figure out. If your room is L-shaped, start by mapping out the shape of the floor. Next, divide the drawing into two square/rectangular shapes and measure the width and length of each shape. Calculate the area of ​​each shape, then add the two areas together. This is your bottom line.

Tile Size – The Dimensions of Your Tiles

The next step is to input the dimensions of the tiles you want to use in your project. Simply enter the length and width of the tile into the calculator, and the calculator will then work out how many tiles you need to tile the wall or floor.


How Can a Tile Calculator Help You?

A tile calculator is designed to simplify the process of measuring and calculating tiles for any given space. It allows you to quickly and accurately determine how many tiles are needed for a wall or floor. 

It also simplifies the process of accounting for obstructions such as windows or doors, by enabling you to calculate the size of individual parts of a wall and then combine them to understand the total area that needs tiling.

Using a tile calculator is important as It ensures that you only buy the amount of materials necessary for your project while also reducing errors in measurements which could lead to costly mistakes during installation.

Having an accurate estimate before beginning your project will help you stay within budget by avoiding the need to purchase additional materials due to miscalculations or unforeseen obstacles, or by having too many tiles left over once you have completed your tiling project.

Ultimately, using our tile calculator can help you save time, money and stress throughout the entire tiling process.

Tips On Using Our Tile Calculator

We’ve designed our tile calculator to be very simple to use, to enable you to get accurate information about how many tiles you’ll need. Whether you need a bathroom tile calculator or want to work out how many tiles you’ll need for your kitchen, hallway floor, or any other area, the tile calculator will work in exactly the same way.

Accurately Measure Your Walls & Floors

Measuring tiles for walls or floors is the most important step in any tiling project as it ensures that the correct amount of material is purchased, reducing costs and wastage.

To begin this process, measure the length and width of the area you wish to tile using a tape measure; be sure to take into account any obstructions such as windows or doors that may alter your measurements (we’ll get to that later). These measurements should then be noted down for use in later calculations with a tile calculator. 

Once all necessary information has been gathered, it’s time to calculate how many tiles will be needed for the wall surface area by entering them into our  tile calculator along with your desired size of tile.

Use the Correct Units

Our calculator uses metres to work out the area of your wall or floor. So if you’re measuring in centimetres, simply divide the number by 100 to convert the value to metres.

Factoring in windows, doors and other obstructions

When planning a tiling project, it’s essential to factor in any windows, doors or other obstructions that may affect the measurements of the area that needs to be covered.

These should be taken into account during the initial measuring process. There are a couple of ways to do this, depending on which is easiest to do in your space. 

Firstly, you can simply subtract their measurements from those of the wall surface and note this information for later use with a tile calculator. 

Alternatively, you can split the wall into smaller rectangles and use the calculator to work out the size of each piece. To do this, simply means the height and length of parts of the wall (for example to the size, above and below a window) and use the calculator for each section individually. You can then combine the total number of tiles needed for each section once they have all been calculated.

Failing to do so could lead to inaccurate calculations, resulting in either too much material being purchased or not enough – both scenarios can prove costly!

Accounting For Tile Wastage

Tile wastage is an all-too-common occurrence when it comes to tiling projects and can be a costly issue if not planned for in advance. That’s why we place so much emphasis on correctly measuring your walls and other tiling areas, making sure you account for the awkward obstructive areas that get in the way.

However, there will always be a certain amount of wastage in any tiling project, and it’s important to account for this when purchasing your tiles.

Wastage can be as a result of dropping or breaking tiles, or of needing to cut tiles to fit around awkward shapes or corners on your wall or floor, and to accommodate things like pipework and vents.

For this reason it is always recommended to add 10% to the number of tiles needed for the project.

For example, if you used the tile calculator to work out that you needed 60 tiles for a surface, it would be recommended to buy an additional 10% to account for wastage, which would mean buying a total of 66 tiles.

Tile Calculator FAQs

How do I calculate how many tiles I need?

Use a tape measure to measure your prospective tiling area. Make sure you’ve noted which unit of measurement you’re using. Once you’ve done this, input this information into the tile calculator alongside the tile size you want. The calculator will then tell you how many tiles you’ll need for your project.

How do you calculate tile squares?

This will depend on whether you have bought the tiles already or are still shopping around.

If you already have your tiles at home, measure the length and height of the tiles and input this information into the calculator. If you are still shopping around, find your favourite tile and open the webpage in a separate tab. Copy the measurements from the page and input them into the calculator. If you have more than one potential tile you’re thinking of buying, repeat the calculation using the different tile measurements

How do you convert tiles to square metres?

Firstly, make sure you’re measuring your tiles in centimetres to avoid any conversion confusion.

1. Measure the length and width of your tile in centimetres.

2. Multiply the two numbers together to get the square cm of your tiles.

3. Divide your answer by 10,000 and that will give you your tiles in square metres.

For example:

Tile length: 20 cm

Tile height: 10 cm

Square cm: 20 x 10 = 200 cm2

Square m: 200/10,000 = 0.02 m2

How many tiles per square metre?

Now that you know how many square metres one tile is, you might want to work out how many tiles would fit into one square metre.

To do so, you simply divide the square metre volume of one tile by 1.

Using the example above:

1/ 0.02 = 50 tiles per square metre

How to work out the cost of tiles per square metre?

Once you know how many tiles you need per square metre, you can simply multiply this by the cost per tile. 

If the cost of the tile you want to use is £1 per tile, using the above example this would be:

50 x 1 = £50/square metre
