Use this area calculator to work out the area of a room.
Enter the width and depth values of the wall in the inputs below and pick a unit of measure from the dropdown.
The resulting area of the wall will be calculated in several different units of measure, both metric and imperial, useful if you are meauring the wall in one unit but for example the wall tiles you want are measured in a different unit.
If you wish to work out the area of more than one wall, or the wall area of an entire room, enter the dimensions for each wall into the calculator below, adding each result together to give you the total wall area of the room.
Do not forget to subtract the area taken up by doors, windows, or any other space that will not need tiling.
