Understanding ring sizes
A cigar is measured by length and ring gauge (diameter). The length is measured in inches. The ring gauge is measured in units of 1/64th of an inch. A 64-ring cigar would be one inch in diameter. Most cigars are between 32 and 52-ring size. For example, a cigar that is called '8 x 48' is 8 inches long and 48/64ths of an inch in diameter. The girth determines how much of the cigar's burning tip is exposed to air. The fatter the cigar, the slower and cooler a cigar smokes because more of the filler is exposed to air. The shape is the length balanced with a particular ring gauge.
