What is the size of a sample swatch?
It varies from 4''x4'' to 4''x12'' inches, depending on the tile. The idea behind the sample swatch offering is for that piece to represent the full-size product. We are committed to sending samples that show at least one piece of each color, texture, material, and size that compose the whole piece. For instance, a sample of a single color/material/size tile will most likely be a 4''x 4''. The same way a sample swatch of a mosaic tile that has clear glass, frosted glass, natural stone, and different colors in a linear pattern, will be at least a 3''x12''.
