Measuring your space: how to calculate tiles needed for a floor or room

When commencing a tiling project, it can be difficult to know just how to calculate tiles needed for a floor or room. The first step is to determine how many tiles you’ll need to get the job done. On the one hand, you don’t want to order too many tiles and have an oversupply, but on the other you don’t want to run out half way through your job and have to go all the way back to the tile shop. Regardless of the tiling job you have at hand, it’s worth doing your due diligence and working out how many tiles you’ll need before starting – this will help you to reduce waste, budget accurately and save money.

 

How to calculate number of tiles needed for a room

 

It’s a simple process (usually) to calculate the number of tiles needed for a room or floor area. All you will need is a piece of paper, pencil, and a tape measure (or a tablet device of sorts). Then you will just need to measure the dimensions of the room with your tape measure. The best way to do this is by measuring one side of the room (length), and then the other side (width) and then multiplying them together to get the area in m.2 Drawing a plan on your piece of paper or tablet can help you to conceptualise the number of tiles needed in your particular space. The difficulty arises when you have an odd shaped room or floor that is tricky to measure (such as a round room). What helps with odd spaces, is to split the space up into smaller rectangles and squares; then you can just add them all together. There are a number of variables that may further affect the number of tiles you need, such as:

 

  1. Tile Size:

 

Tiles can range in size from small mosaic tiles through to large slab tiles. Obviously, your choice here will determine just how many boxes of tiles you will actually need to purchase to cover the area you’re tiling. People often go for tiles with straight edges either in a square or rectangular shape. Large tiles are great for making a room look bigger.

 

  1. Tile Layout Pattern:

Tile layout pattern refers to the way in which you lay the tiles on your floor or wall. There many different patterns used to install tiles, but most square and rectangle tiles follow a linear pattern. Other tiles such as herringbones tend to be laid at angles of 90 or 45 degrees. The way you lay your tiles will affect how many you will need to purchase. For example, if you start laying them without a plan you may end up wasting more tiles as you may need to cut them down to size; or pull them up if laid incorrectly (likely if you haven’t planned). Our top tip is to always plan your layout, regardless of whether you’re tiling a whole room or just a splashback.

 

  1. Gap Size between the Tiles:

A grout joint is essential to allow for the natural variations in the shape of the tiles, as well as allowance for some movement to prevent cracking. The gaps are filled with grout, which can be blended with the colour of the tile or contrasted for effect. You should choose the tile, decide on the tile pattern, and chose a grout colour before starting. A smaller grout joint is easier to maintain, and will make your space appear bigger. Porcelain tiles that have a rectified edge or straight edge, a 1.5mm joint is recommended. Whereas for some ceramic cushion edge tiles, 3mm is recommended. Once you calculate how many tiles you need to tile your wall or room, you should add an extra 10% to 15% on top, for wastage.
