Our handy TILE CALCULATOR

Quick and easy guide to measuring your bathroom, kitchen, Hallway and any other room.

Calculating the area of a wall:

To calculate the area of a wall you will need to measure (we recommend at first in cm) the height and width of the wall (see below diagram). Then divide separately the height and width measurements you have taken in cm by 100, this will convert the measurement in metres.

Example: height 240cm / 100 = 2.4m, width 300cm / 100 = 3m

Multiple the two measurements together, this will then give the area of the wall in square metres.

Example: height 2.4m x width 3m = 7.2m2

Repeat this for the number of walls you’re wanting to tile. If you have an area that is trickier to measure like an L-shape we recommend breaking this down into square areas to make it much easier to calculate the area. If there is a door, window or both on the wall you’re wanting to tile you will need to repeat this process and measure the height and width of them. Multiple the two measurements together and then subtract this from the overall area you’ve calculated using the above method, this will then give you a total area which you can use to calculate the number of tiles you require.

Top tip: When calculating the number of tiles your require for your bathroom or kitchen walls, we recommend adding 10% to allow for cutting waste, breakages and a few spares.

Calculating the area of a floor:

To calculate the area of the floor you will need to measure (we recommend at first in cm) the depth and width of the floor (See below diagram). Then divide individually the height and width measurements you have taken in cm by 100, this will convert the measurement in metres.

Example: depth 400cm / 100 = 4m, width 250cm / 100 = 2.5m

Repeat this for the number of floors you’re wanting to tile. If you have an area that is trickier to measure like an L-shape we recommend breaking this down into smaller square areas to make it much easier to calculate. If there is a bath, shower or another object that you don’t want to tile underneath you will need to repeat this process and measure the depth and width of the object you’re wanting to exclude. Multiple the two together and then subtract this figure from the overall area you’ve calculated using the above method, this will then give you a total floor area which you can use to calculate the number of tiles you require.

Top tip: When calculating the number of tiles your require for the floor of your bathroom, Kitchen Hallway or other room, we recommend adding 10% to allow for cutting waste, breakages and a few spares.
