How To Measure Your Room For Floor Or Wall Tiles

If your ready to go ahead and order tiles for either a wall, a floor or even both! Then its a good idea to know the exact amount (Or m2 coverage) you will need so you aren’t left with a surplus of expensive tiles sitting in the shed, or even worse you get towards the end of the installation only to realise that you are going to come up short and will have to place a further order and pay again for delivery!

A Quick Note About Tile Retailers & How To Measure.

Online tiling retailers sell their products in differing ways so its useful to know how your chosen supplier will calculate your order. Generally there are two schools of thought here;

  1. Retailer sells tiles by the square meter (m2)
  2. Retailer sells individual tiles ie Customer requires 25 tiles at £5.00 per tile = £125.00

We sell a vast range of tiles and within each individual product we sell differing sizes! Therefore it is far easier for our customers (and us!) that we sell by the square meter (m2) so you only need to calculate the area required and place your order.

However if your chosen supplier requires you to calculate how many actual tiles you need, you first need to work out what is the size of the chosen tile? What surface area you need to cover? And then calculate the number required to cover said area!

This can be tricky, especially if you want 2 or more differing tile sizes in your installation. However to assist you, even if you decide to purchase elsewhere here is a simple tiling calculator, you will still need to work out your required area so read on.


Step By Step Guide To Measuring For Floor & Wall Tiles

In our easy to follow guide of how to measure your room our images show a wall, however the same rules apply for a floor!


What you will need;

  • A good quality tape measure
  • Notepad
  • Pen Or Pencil
  • Calculator
  • Possibly an eraser 😉

Ok lets begin;

Step 1 – Measure The Total Surface Area Of The Floor Or Wall

  1. Measure the width of the wall or floor = A
  2. Measure the height or length = B
  3. Multiply A x B = X
  4. X = The total suface area of the floor or wall to be tiled.

OK make a note of this area eg 8 m2 now you are ready to move on to step 2

Step 2 – Remove areas not to be tiled or obstructions

Now subtract the areas of floor or wall not to be tiled! In our example we are using a door and a window, but this is exactly the same calculation for say a kitchen island or a bath.

  1. Calculate the width (C) & height (D)of the door. C x D = Y (Total surface area of the door).
  2. Calculate the width (E) & height (F) of the window E x F = Z (Total surface area of the window).
  3. Add these areas together Y + Z = (O) Total area not to be tiled, or total are for obstructions.

Again make a note of this figure and you are now ready to move to step 3


Step 3 – The Final Calculation

So now you will have the total surface area = (X) And the total are you do not need to be tiled = (O)

Simply subtract the two figures

X – O = Required tile surface area in m².




What should I order to allow for waste, cuts and spares?

We normally recommend that you allow 10-15% for cuts and wastage. You should always ensure you have some tiles left over for spares should you need them in the future.
