(for cuts and wastage)
Use our handy calculator to help work out how many tiles you'll need for your project. Or read the guide below to help working out the measurements.

For a standard square floor using say 600 x 300mm tiles laid in a lineal pattern, measure the length of the room, and divide that by the length of the tile.
For example:- if the room is 4400mm long divide it by the length of the tile 600mm = 7.33 tiles, whatever the answer is round the calculation up to the next full tile, in this example 8 to allow sufficient tiles for offcuts.
To set out the room, divide it equally in half, marking a line at 2200mm across the room, this will give you the same size cut against each wall. This centre line will either be the centre or the edge of the tile for your setting out, leaving you with a small or larger cut to the wall. It always looks better with a larger cut and is easier to do. If you are laying the tiles in a brick effect, then the centre line will be at both the edge of the tile on one run, and the centre of the tile on the next run of tiles.
Repeat the above for the width of the room.
For example:- if the room is 2600mm wide, divide by the tile width 300mm = 8.66 tiles, so round this up to 9 tiles.
To get the total number of tiles for the floor, multiply the number of tiles for the length with the tiles for the width, 8 x 9 = 72 tiles required to do the job.
The calculations above allows for offcuts, but not breakages, so always allow a small amount extra, even if they don’t get used.
A 10% extra is usually enough to cover both breakages and offcuts – that way you have a few spare tiles that are from the same batch to keep in case of accidents or damage in the future.
For a wall with a door in it, break this down to separate pieces, to the left of the door, to the right, and above the door. For a window wall, depending on window size and depth of the reveals/ window cill etc, think of this as a the lid of a cardboard box folded inwards, if you were to unfold them, you would cover most of the hole, so best to measure the complete wall.
For an L shaped floor, find the centre line of each part of the L shape, and where the lines cross, this will be the starting point, as above either with the centre, or the edge of the tile could start on this line depending if you have a small or large cut to the wall.
Use the same way of calculating as in the diagram, remembering that if you are using a rectangular tile, that in one direction of the L shape, the tile will be laid length ways, and the other part of the L shape it will be laid width ways, so think about which way will look best before starting, this would usually be with the tile length being laid with the longest part of the L.
