Therefore, get to know the various sizes and discover which one is right for you. Remember that the length of a cigar is measured in inches and the ring size, (girth), of a cigar is measured in 64ths of an inch.

Here are the more standard cigar sizes and shapes.

Petit Corona - This short corona averages only 4.5 inches with its ring gauge being 40 to 42.
Corona - Traditional formats are 5.5 to 6.0 inches with a 42-44 ring gauge.
Churchill - Basically a large corona. Dimensions hover around 7.0 inches in length by a 48 ring gauge.
Robusto - A short Churchill. Usually 5.0 to 5.5 inches by a rather stout 50 ring gauge.
Corona Gorde - Long robusto. Measures are 5.0 & 5/8's inches by a 46 ring gauge.
Toro - A very popular size. This cigar is 6.0 x 50 in the classic state.
Double Corona - Standard format is 7.5 to 8.0 inches by a 49 to 52 ring gauge.
Panetala - Shaped akin to a longer, thinner corona. Varies from 5.0 to 7.5 inches with a 34 to 38 ring gauge.

Culebra - A rather unusual shape is this one. This consists of three panatelas which are braided together and made to look like one twisted cigar. These are usually 5.0 to 6.0 inches in length with a ring gauge around 38. Just for the record...the cigars are designed to be seperated before smoking.
