It goes without saying that today’s tiles come in more sizes, shapes, patterns and colors than ever before. Along with this availability comes virtually endless creative possibilities. Today we will focus on one of these options—the pattern.
When using an offset pattern, it is best to follow the American National Standards Institute (ANSI) guidelines. ANSI A108.02 section 18.104.22.168 states, “For running bond/brick joint and any offset pattern (i.e. non-continuous grout joints) utilizing tiles (square and/or rectangular) where the side being offset is greater than 15 in. (nominal dimension), the offset pattern will be a maximum of 33% unless otherwise specified by the tile manufacturer. If an offset greater than 33% is specified, specifier and owner must approve mock-up and lippage.”
