What Is Ring Gauge?
Cigar ring gauge refers to the diameter of a cigar, not its length or circumference.
The number represents how many 64ths of an inch wide the cigar is.
For example:
- 64 ring gauge = 1 inch in diameter
- 32 ring gauge = ½ inch in diameter
Many cigar smokers search for ring gauge in cm to better understand cigar thickness in metric measurements, especially outside the United States.
How to Convert Ring Gauge to CM
Ring gauge is measured in 64ths of an inch. To convert ring gauge to centimeters, use the formula below:
(Ring Gauge ÷ 64) × 2.54 = Diameter in cm
For example:
- Ring gauge 50 in cm equals 1.98 cm
- Ring gauge 54 in cm equals 2.14 cm
- Ring gauge 60 in cm equals 2.38 cm
- Ring gauge 64 in cm equals 2.54 cm
This formula works for any cigar size.
Common Cigar Ring Gauge Sizes
Most modern premium cigars fall between 46 and 64 ring gauge. Here are a few examples:
- 40–44: Petit Corona & Corona
- 48-52: The very popular Robusto
- 50–54: Toro (Also very common)
- 56+: Gordo, Double Toro and the quite recent "NUB" format to mention a few
While thinner cigars still exist, today’s retail market strongly favors medium to large ring gauges. Sizes between 48 and 60 dominate humidor shelves worldwide. You can read more about Cigar Sizes here.
Typical Smoking Time by Ring Gauge
Smoking time depends mostly on length and how slowly you smoke, but ring gauge plays a role. Thinner cigars tend to burn faster, thicker cigars slower.
As a rough guide, many 46–52 ring gauge cigars (common Robusto sizes for example) land around 40–60 minutes, while 50–54 (many Toros) often run 50–90 minutes.
Larger 56–60 ring gauge cigars can take 75–120+ minutes depending on length and pace, especially if you smoke slowly.
Why Ring Gauge Matters
Ring gauge affects:
- Draw resistance
- Smoke temperature
- Burn rate
- Flavor balance
- Mouthfeel
Thicker cigars generally burn slower and cooler due to increased filler tobacco.
Thinner cigars, or cigarillos, tend to emphasize wrapper flavor and may burn slightly hotter.
For beginners, understanding ring gauge makes it easier to estimate how thick a cigar will feel in hand and how long it may take to smoke.
When lighting larger cigars, especially around 56 ring gauge and above, a torch lighter often provides a more even and efficient ignition compared to a traditional soft flame. The wider foot of a large ring gauge cigar benefits from stronger, concentrated heat to ensure a proper burn from the start.
