Q. What is the standard size of tile spacers?

Answer

For floor tiles tile spacers with a minimum width of 3 millimetres should be used regardless of the type or style of tile being used (porcelain ceramic or stone). It is possible for the needed spacing to be as high as 10 millimetres depending on the tile. In most situations a spacer of 5 millimetres is employed and this is particularly true when transitioning from indoor to outdoor tiles.
