Selecting the appropriate tile size for a space is not a simple task. It involves not just taking into account space available, but also the usage of the particular room. Tiles are available in a variety of sizes, for residential and commercial applications. The straightforward formula to get tile size right is to select a size that is proportionate to the size of the area you are covering. For example, if you are looking for tiles for an open space, like a large living room, it is best to opt for large format tiles. Similarly, for a medium sized space, such as a bedroom, you can opt for medium tiles, and maybe small tiles for a corridor or kitchen backsplashes. Keep the overall design scheme and aesthetic in mind while choosing the tile size for your space.
