A cigar shape can vary greatly in size from brand to brand, so describing a cigar by its size as well as shape is important. Cigars are measured by two factors: length, which is given in inches, and “ring gauge,” a designation of a cigar’s diameter broken into 64ths of an inch. A cigar with a 42 ring gauge, for example, is 42/64 of an inch in diameter.
There is no correlation between the size of a cigar and its strength. An 8-inch cigar made with mild tobaccos will be mellow, while a thin, short cigar rolled with powerful tobaccos will be full bodied. While a cigar’s strength is determined by the tobacco it is rolled with, thin cigars have a tendency to burn hotter than fatter ones. Also important to note is that there is no consistency of strength from brand to brand: one company’s corona is likely to taste very different from another’s.
