When planning a tiling project, the key question should always be: how many tiles do I need? This helps you calculate not only your budget but also makes sure you buy enough tiles for the job.

If you are tiling a kitchen wall, using the same batch means you will get consistency across the colour and style but there is always the scenario that the tiles could be discontinued or changed slightly. This is a frequent problem when hoping to use the same style tiles across different rooms but are decorating them on different timescales. 

Here we give some simple tips to calculate how many tiles you will need for walls and floors to make sure you can get the job done in one go.
