Tile Size Considerations
Tile comes in virtually any size and shape you can imagine – ranging from small mosaics less than inch in size to single tiles up to 8 foot in length. Choosing the size (or format) of the tile is really dependent on taste, room size, style and budget.
As a rule of thumb, the less grout joints you have, the larger the room will feel. This creates less breaks in the tile giving a clean and sleek look. On the other hand, the larger the tile, the flatter your floor needs to be prior to installation and hence the more expensive the installation. Other considerations, like anti-slip requirements and room layout also play into the criteria for choosing the right size tile for your project.
There is definitely a strong trend worldwide towards tiles larger than 12″x24″ with tight grout joints (approximately 1/8″ in size) and this is in part due to the major innovations in tile manufacturing that makes these tiles now available at a small premium.
