Looking for barcode dimensions? We can provide you with information about the official standards for barcode size and symbol dimensions. It’s important to keep these in mind when putting barcodes onto your products, especially if you are re-sizing or truncating the barcodes. If your barcode is too small, some barcode scanners may not be able to read it.
