Barcodes,Inc.

 Guest We have chosen a standard Interleaved 2 of 5 format which supports only numeric characters. Could you tell me the smallest size the bar code label could be? This is going onto a small disposable patch primarily used on infants and neonates. Not a lot of real estate.

Technically there is no smallest size you could make a bar code. From a practical point however there is a limit at which a code will become too hard to read. A bar code’s density is based on how physically wide it is, the number of characters, and the symbology type used. Most scanners do not read below a density rating of 5mil and this would require a higher resolution label printer to make the code in the first place. Seagull Scientific’s Bartender software is a simple to use label application that would allow you to see how small things can become in your case before you would run into reading difficulties.
