We use the metrics system for its length, and we added inches to help you choose on the size that fits your style 152 mm (6 inches). Our ring gauge is measured in units of 1/64th of an inch. A 64-ring cigar would be 1 inch in diameter. For instance, a cigar called “8 x 48” is 8 inches in length and 48/64ths of an inch in diameter. The girth restricts how much of the cuban cigar’s burn tip is exposed to oxygen. The thicker the cigar, the slower and cooler the cigar smokes because more of the filler is exposed to oxygen. The body shape is the length balanced with a distinct ring gauge.
