Barcode Sizes
The table below lists formulae for figuring the approximate dimensions of printed barcodes.
The dimensions of the barcode printed may vary, even when using the same program, depending on
conditions such as the characteristics and resolution of the printer used, paper quality, etc. The
dimensions derived from the formulae in this table are not guaranteed to be the actual dimensions of
the printed barcodes. Use this table as a reference when estimating the size of printed barcodes.
