... interesting ditty I found on the web on cigar sizes and shpes, for anyone who's interested:
Sizes & Shapes
Cigar shapes and sizes have two dimensions: length(either in centimeters or inches) and ring gauge, a measurement divided into 64ths of an inch(or, in the European method, millimeters). A cigar with a ring gauge of 40 for example, measures 40/64ths of an inch in diameter. There are two basic types of shapes: Straight sided and Figurados(Shaped). Straight Sided Cigars Churchill: A large corona format. The traditional dimension is 7 " x 48 ring.
Corona:
The traditional proportion is 5 1/2 to 6 " x 42 to 44 ring
Corona Gorda:
This long robusto could be called a robusto extra. The traditional measurements are 5 5/8 " x 46 ring.
Double Corona:
The standard dimension is 7 1/2 " by 49 to 52 ring.
Lonsdale:
The classic size is 6 1/4 " by 42 to 44 ring
Panatella:
More popular in years past than today. This format varies more widely in length than almost any other cigar size. Sizes vary from 5 to 7 1/2" by 34 to 38 ring.
Petit Corona:
This short corona is usually 4 1/2 " by 40 to 42 ring gauge.
Robusto:
This short Churchill format is growing in popularity. The traditional size is 5 to 5 1/2 " by 50 ring gauge.
Figurados or Shaped Cigars Belicoso:
Traditionally, a belicoso was a short pyramid, 5 or 5 1/2 " with a shorter more rounded taper at the head and a ring gauge generally of 50 or less.
Culebra:
The most exotic shape is actually three panatellas braided together and banded as one cigar. You smoke them separately. They are usually 5 to 6" by 38 ring gauge.
Diademas:
A true torpedo. The head and foot on this cigar are both closed. It is usually 8" or longer and is often boxed individually. It has a rung gauge of 40 at the head and 52 to 54, or even larger at the foot.
Perfecto:
This cigar is closed at both ends. The head is rounded, not tapered. The foot is closed like a torpedo or a diademas. It is usually shaped with a bulge in the middle. Perfectos can vary greatly in length, from 4 1/2 to 9 " by 38 to 48 ring gauge.
Pyramid:
A tapered head cigar with an open foot(the end you light). These cigars are between 6 and 7 " with a ring gauge of around 40 at the head that widens to between 52 and 54 at the foot.
