 All barcodes have an **X dimension**, which is the width, in thousandths of an inch, of the narrowest element (bar or space) in a barcode. This is usually referred to in **mil**. So a .002" bar width would be referred to as a 2-mil label. As we will see in the screenshot below, the minimum X Dimension for reliable day-to-day use is 2-mil.  However, a well maintained printer may print a 1-mil barcode using the right label and ribbon format (also shown below)
 === Wide-to-Narrow ratio ===
-This is how much wider are the wide bars than the narrow bars, and is limited by the symbology and printer used.  Code 39 can be 2:1, 5:2, or 3:1.  Whereas, Code 128 can be 2:1, 3:1, 4:1.
+This is how much wider are the wide bars than the narrow bars, and is limited by the symbology and printer used.  Code 39 can be 1:2, 2:5, or 1:3.  Whereas, Code 128 can be 1:2, 1:3, and 1:4.
 === Quiet zone ===
-Barcodes need some white space on the left and right side of them for a barcode to scan properly.  This should be 10 time the width of the mil size.  So a 1-mil barcode needs a quiet zone of 0.010" or 2.5mm, and likewise a 2-mil barcode needs a quiet zone of 0.020" or 5.1mm.
