Somewhere on the box, usually just after the length, sits a second number. A robusto might read five by fifty. A lancero, seven and a half by thirty-eight. That second figure is the ring gauge, and for something so quietly printed it stirs a surprising amount of opinion.
The short version is this: ring gauge is the diameter of the cigar, and a larger one is not automatically a finer smoke. What it changes is the character of the thing in your hand, how it burns, how it draws, and which part of the blend you notice most. Once you can read the number, you can choose with intent rather than habit.
What Ring Gauge Actually Measures
Ring gauge is measured in sixty-fourths of an inch. A fifty ring gauge cigar is fifty sixty-fourths across, a shade over three-quarters of an inch. Push the number to sixty-four and you have a cigar a full inch in diameter, which is about as wide as most people care to go. The figure is taken at the cigar’s widest point, and the length in inches is the number printed beside it.
So five by fifty means five inches long and fifty sixty-fourths thick. Seven and a half by thirty-eight, the classic lancero, runs longer than most and yet sits noticeably slim in the fingers. Neither measurement tells you anything about strength or quality on its own. They describe the shape of the cigar and very little else, which is precisely why the number is worth understanding rather than trusting.
What a Wider Gauge Changes in the Smoke
A wider cigar holds more filler leaf beneath the same wrapper. If those parts are new to you, the anatomy of a cigar sets them out plainly. That extra room does a few practical things. The burning coal sits in the middle of more tobacco and pulls in more air with each draw, so a fat cigar tends to burn cooler and slower, and the smoke arrives gentler on the palate. The draw feels looser and the smoke more generous in volume.
It also gives the blender more to work with. More filler means more leaves can be layered together, which is why larger sizes are often built for a rounder, more complex middle. A thinner cigar works the other way. The wrapper, which carries a good deal of a cigar’s flavour, makes up a larger share of the whole, so a slim vitola tends to taste more focused and wrapper-led, and it burns a touch hotter and quicker for the same reason. Knowing this is half of learning to taste what you are smoking.
The Swing Toward Bigger, and the Pushback
For most of the last quarter century the market has drifted steadily wider. The fifty to fifty-four toro became the default on most shelves, and the sixty ring gordo, once a novelty, now sits in almost every maker’s catalogue. A few brands have pushed the idea further still, into territory no ordinary cutter or ashtray was built for.
Not everyone followed. A good many seasoned smokers hold that the finest wrappers show themselves most clearly in slimmer formats, and that a well-made forty-six reveals a leaf a sixty would smother. There is a fair case to it. A delicate Connecticut shade wrapper has more of a voice on a lancero than on a gordo rolled from the same tobacco. If you would like to see how a handful of shapes stack up side by side, the Cigarro vitola dictionary lays them out. Neither camp is wrong. A gordo and a lancero are simply asking for different evenings.
Cigar Ring Gauge Chart: Every Size, Diameter and Fit
Sizes vary between makers, so treat the vitola names here as typical rather than universal, and the smoke times as a guide rather than a stopwatch. Ring gauge itself never wavers. It is simply a cigar’s diameter in sixty-fourths of an inch, so a fifty ring gauge cigar is fifty sixty-fourths across by definition, not by tradition.
| Ring gauge | Diameter (mm) | Diameter (64ths) | Vitolas cut at this gauge | Typical smoke time |
|---|---|---|---|---|
| 38 | 15.1mm | 38/64″ | Lancero (7 to 7.5 x 38), slim Panetela | 60 to 90 minutes, longer with a patient hand |
| 40 | 15.9mm | 40/64″ | Modern Lancero, Panetela | 55 to 75 minutes |
| 42 | 16.7mm | 42/64″ | Corona, Petit Corona, Lonsdale (6.5 x 42) | About 40 minutes |
| 44 | 17.5mm | 44/64″ | Corona (upper end), Corona Grande | 40 to 45 minutes |
| 46 | 18.3mm | 46/64″ | Corona Gorda, Grand Corona | About 45 minutes |
| 48 | 19.1mm (exactly 3/4 in) | 48/64″ | Churchill (traditional) | 60 to 90 minutes |
| 50 | 19.8mm | 50/64″ | Robusto, short Toro | 45 to 60 minutes |
| 52 | 20.6mm | 52/64″ | Toro (modern standard) | 60 to 75 minutes |
| 54 | 21.4mm | 54/64″ | Belicoso, fat Toro | 45 to 75 minutes, depending on length |
| 56 | 22.2mm | 56/64″ | Grandes-class cigars (Cohiba Behike BHK56, Saint Luis Rey Serie G) | 60 to 75 minutes |
| 60 | 23.8mm | 60/64″ | Gordo (6 x 60) | 75 to 90 minutes |
| 64 | 25.4mm (exactly 1 in) | 64/64″ | E.P. Carrillo’s Inch line | 90 minutes or more |
| 70 | 27.8mm | 70/64″ | Perdomo Inmenso Seventy | A long, unhurried sitting, well past 90 minutes |
| 100 | 39.7mm | 100/64″ | JFR Lunatic Belicoso Maduro (10 x 100, see below) | Several hours, rarely finished in one sitting |
The Churchill and the robusto make the point nicely. Many blends offer both, and the same family of flavours smokes as a very different hour depending on which you reach for. If you want them set against each other properly, we have compared the Churchill, toro and robusto in their own right.
What About a 100 Ring Gauge Cigar?
A cigar can, in principle, keep growing forever, and every few years someone tests that principle in earnest. The hundred ring gauge cigar is not a myth or a marketing rumour. Aganorsa Leaf’s JFR Lunatic Belicoso Maduro measures ten inches long by a full hundred ring gauge, a diameter of nearly forty millimetres, wrapped in a dark Mexican San Andrés leaf over Nicaraguan binder and filler. It ships in a wooden coffin rather than a box, production is capped at 2,500 a year, and at under forty dollars it is priced more as a curiosity than an investment.
It is not even the largest cigar ever rolled. In 2013 RoMa Craft Tobac produced a limited CroMagnon Femur vitola at ten inches by a hundred and thirty-three and a third ring gauge, a size that exists mainly to prove it can be done. Cigars at this scale are not really built for the humidor rotation. Nobody smokes a hundred ring gauge cigar in an evening, and few finish one in a single sitting at all. They belong to the same family as a novelty pumpkin at a country fair: worth admiring once, rarely worth repeating, and a useful reminder that ring gauge, past a certain point, stops describing a smoke and starts describing a spectacle.
Bigger, Smaller, or Simply Yours
That leaves the practical question of which to reach for. If you have an hour and want the cleanest read on a blend, a robusto around five by fifty rarely puts a foot wrong. If the evening is long and unhurried, let a toro or a Churchill stretch out. When you want the wrapper to sing, go slim. The number is a lever, not a verdict.
The surest way to find your own preference is to notice it. Note the ring gauge beside your tasting notes, and after a dozen cigars a pattern tends to appear. Most smokers are quietly loyal to a size long before they realise they have chosen one.
