A premium cigar takes somewhere between twenty minutes and two hours to smoke, and almost all of that spread comes down to two things: the size of the cigar and the pace of the person smoking it. A robusto is a forty-five minute cigar for most people. A toro runs closer to an hour. A Churchill wants an hour and a half, and a double corona will happily take the whole evening. Those are the figures to plan around, and the rest of this piece explains why they are ranges rather than promises.
The honest answer matters because choosing a cigar is largely choosing a block of time. Light a Churchill with twenty minutes to spare and you will either abandon it or rush it, and rushing a cigar is the surest way to make a good one taste bitter. Here is how long each of the common sizes takes, what actually moves the number, why speed ruins the smoke, and what to do when the evening ends before the cigar does.
The short answer, by vitola
Cigar size is written as length in inches by ring gauge, the diameter in 64ths of an inch, and both numbers push the clock. Longer cigars have more tobacco to burn through. Thicker ones burn cooler and slower, so a fat short cigar can outlast a thin long one. With that in mind, here are the working figures for the sizes you will actually meet at the counter.
A petit corona, around four inches by a 42 ring, is a twenty-minute cigar and the right answer for a cold balcony. A corona, five and a half inches by 42 or so, runs about forty minutes. A robusto, the classic five by 50, sits between thirty and fifty minutes depending on who is holding it. A toro at six by 50 or 52 takes fifty-five minutes to an hour. A Churchill, seven by 47 to 49, is an hour at a brisk pace and closer to ninety minutes at a considered one. A double corona, seven and a half by 50 or more, is the longest sitting of the lot at seventy-five minutes and upwards.
The robusto figure deserves a word, because the trade’s own references do not agree. Cigar Aficionado’s glossary puts a five by 50 at twenty to thirty minutes. Holt’s puts the same cigar at forty-five to fifty. Neither is wrong. The gap is pace, and it is roughly the difference between a smoker who draws every thirty seconds and one who draws every minute. If your robustos are finishing in twenty-five minutes, the cigar is not short. You are quick.
The three sizes that matter most, and how they suit different evenings, are compared side by side in our robusto, toro and Churchill guide. The full roster of named sizes, from the lancero to the gordo, lives in the Cigarro vitola dictionary.
What actually moves the number
Size sets the range. Four other things decide where in the range you land.
Ring gauge. Thicker cigars burn cooler and slower because there is more tobacco between the ember and the air. A 60 ring gauge stub will often outlast a slim seven-inch lancero, which is why the thick short formats have found an audience among people with an hour to spend but not two. The full physics of it is in our ring gauge explainer.
The cut and the draw. A punch or a V-cut leaves a smaller opening than a straight cut, which restricts the draw and slows the burn. A wide guillotine cut gives a looser, faster-burning cigar. A cigar rolled tight will resist and burn slowly; one rolled loose will race. None of this is a fault. It is just a variable to plan for.
Your cadence. The single largest factor, and the only one you control entirely. More on this below, but the short version is that a cigar smoked at a draw a minute takes nearly twice as long as the same cigar smoked at a draw every thirty seconds, and tastes considerably better for it.
Wind and weather. A breeze feeds the ember with oxygen and shortens the smoke noticeably, which is one reason a cigar on a windy patio never seems to last. Cold air does the same by pulling heat out of the foot faster. Humidity works the other way: a cigar stored wet burns slower and often reluctantly, which is why some smokers dry-box a stick for a day before an important evening.
Why rushing ruins it
The guideline every good tobacconist will give you is one draw a minute, give or take. Holt’s frames it as a pause of about thirty seconds between draws; Famous Smoke’s Cigar Advisor says roughly once a minute. Either way, the point is the same: the ember needs time to cool between puffs.
Puff faster than that and the foot overheats. Hot tobacco chars ahead of the burn line, the smoke turns harsh, and a bitterness sets in that usually does not go away, however well the cigar started. To my palate a rushed cigar loses its sweetness first, then its distinctions, until every third tastes of the same scorched note. The blender’s work is in the layers, and heat flattens them.
There is a second cost. Cigar smoke is not inhaled, but nicotine still reaches you through the mouth, and a cigar taken fast delivers it fast. That is the buzz some newcomers chase and the nausea that puts a good number of them off cigars altogether. Slow smokers rarely meet either.
Two small habits help. Let the ash grow to an inch or so before knocking it off, because a good column of ash insulates the ember from the air and keeps the burn cool. And rotate the cigar a quarter turn every few draws so one side does not run ahead of the other. If you are working through the review-by-thirds framework, the slower pace also gives each third the time it needs to show you something.
When the evening ends before the cigar does
You are under no obligation to finish. A cigar that has grown too strong, too hot, or simply outlasted your evening can be set down without ceremony. Many experienced smokers stop somewhere around the band and consider the job done; others prize the last two inches above everything. Neither is a rule.
If the cigar was good and the interruption was brief, let it go out on its own and relight within the hour. Purge it first with a gentle blow through the head to clear the stale smoke, then toast the foot and carry on. The technique is covered in our guide to relighting a cigar.
Saving a half-smoked cigar for tomorrow is possible, with honest expectations. Snip the ash and the charred end cleanly with your cutter, seal the cigar in an airtight bag or tube on its own, and keep it well away from the humidor, where the sooty smell would taint everything around it. Relit the next day, it will open with a charred note that takes a few draws to burn off, and it will never quite taste as it did the first time, because the oils in the tobacco set as the cigar cools. Beyond a day it is not worth the trouble.
The better solution is upstream. Look at the clock before you look at the humidor, and pick the size that fits the time you actually have. Thirty minutes is a petit corona. An hour is a robusto or a toro. A free evening is what Churchills are for. Get that habit right and you will rarely have to save anything.
Log the time with the tasting notes
Time is the one ingredient the blender cannot put in the box. A cigar gives you its best somewhere around a draw a minute, and the sizes exist so you can match the smoke to the sitting rather than the other way round. Choose by the clock, smoke slowly, and note the smoking time alongside your tasting notes each time, because your own average is a far better guide than anyone’s chart. The next time you have forty minutes and a robusto, you will know exactly what to do with both.
