Samples are usually 4inch x 4inch or 6inch x 6inch based on the type of tile. These samples are just a representation of the actual tiles for you to see the color and texture of the tiles. Samples are shipped by Fedex / USPS ground service, sometimes the samples are not in good shape on delivery as they are individually packed and lack the proper safe packaging as the actual tile order. Nevertheless they solve the purpose of showing you the color, texture and the pattern of the tiles.
