Ladies' ring sizes are measured by wrapping a piece of string around the finger to be measured. The length of string is then measured against a chart called a ring sizer, and the length of the string will line up to the correct ring size.
"Ring" refers to the diameter of the cigar. It's in 1/64ths of an inch, so a 32 Ring cigar is 32/64" in diameter, or one-half inch. A 48 Ring cigar is 3/4" in diameter, and so on. Apparently there's a ring gauge you can get to measure cigars; it would have holes in it in various sizes, and whichever hole the cigar fits snugly into is the cigar's ring size. You could also use a ruler, calipers, just whatever you wanted.You might see a cigar specified as 6-1/2" x 42 ring. This cigar would be six and a half inches long by 42/64"in diameter. (The name for this size is Lonsdale.)Box-pressed cigars also have ring sizes, although those cigars are square--a 48 Ring box-pressed cigar is 3/4" x 3/4".
