1. The use of large format tiles has the effect of making a space appear larger. The standard size for large format tiles is 300 millimetres squared or more. Those tiles are large enough to cover more ground, making the room look bigger than it is. This makes them a great choice for areas when space is at a premium yet an air of spaciousness is required.
2. Because of their size, large format tiles require a perfectly flat and even surface in order to be put correctly. The tiles could break or become uneven if placed on such a surface. Be sure the surface has been properly prepared for large format tiles before beginning installation.
3. Because of their potential bulk, large format tiles, especially those made of real stone or ceramic, should be installed with care. As a result, you may have a harder time transporting and handling them, therefore it's crucial that you come prepared with the right hardware for a safe installation. It is probable that the surface they are being built on will require reinforcement to support the weight of the tiles once they are completed.
