Barcodes can come in a wide range of sizes, with some 2D codes going as small as a 1/8th inch square. Generally speaking, however, the smaller a code becomes, the more difficult it is to read. Smaller barcodes limit the amount of characters you can use and are required to be printed at high resolutions to ensure that they will be readable by a scanner or imager.
