how do you calculate the narrow and wide bar widths for a barcode using LPI?

Best answer:

LPI is “lines per inch” so if you have 8 LPI then you have 8 lines per inch so one line is (1 inch)/(8 lines) = 1/8 inch.

If your wide bars are 5 lines and your narrow are 2 lines then wide bars are 5/8 inch wide and narrow are 1/4 inch (or 2/8 inch).

Many fonts are done in points. There are 72 points per inch. So if you have 8 LPI (lines per inch) then you have 72/8 points per line. Multiply the number of lines by 9 to get the number of points.
