Before we talk about the Shape and Size of a Cigar, it is important to understand that the same terminology of a Cigar shape/size can vary from brand to brand. That is why, we usually describe the shape by mentioning the Shape and Size together, which will form the identification label of the Cigar itself.

It is important as well to note that the Cigar shape and size can never be a hint for how strong a Cigar is: it is irrelevant. Moreover, a Robusto size at one brand might be full bodied (for example), where the same size at another brand can be medium.

So, Cigars are measured by their Length (in Inches mainly) and their “Ring Gauge”, which is the measurement of their diameter. All sizes are grouped under two main categories:
– Parejos,
– Figurados.

Parejos:
They are usually straight sided Cigars, with the foot open ended where we light them. Many sizes are grouped under the Parejos, we will list them from smaller to bigger:

1. Petit corona: 4 1/2″, 40 to 42 ring gauge.
2. Robusto: 4 3/4 to 5 1/2″, 48 to 52 ring gauge.
3. Corona: 5 1/2 to 6″, 42 to 44 ring gauge.
4. Corona Gorda: 5 5/8″, 46 ring gauge.
5. Toro: 6″, 50 to 52 ring gauge.
6. Churchill: 7″, 47 ring gauge.
7. Panetela: 5 to 7 1/2″, 34 to 38 ring gauge.
8. Double Corona: 7 1/2 to 8 1/2″, 49 to 52 ring gauge.

Figurados:
Any cigar that is not a straight sided size, thus does not fall under the “Parejos” category. Same as above, we will list them from smalled to bigger:

1. Belicoso: Short Pyramid, 5 to 5 1/2″, 50 ring gauge.
2. Pyramid: 6 to 7″, ring gauge starts with 40 at the head and ends with 50 to 52 at the foot. (please do not confuse between a Pyramid with an open foot and a Torpedo with a closed foot).
3. Torpedo: It’s kind of a Pyramid, but with a closed foot and a tipped head. This type of Cigars is rare, that is why nowadays it is confused with the Pyramid size.
4. Perfecto: It has many sizes (from 4 1/2 to 9″, and a ring gauge from 38 to 48).
