Choosing the right case for the size of your cigars – 2025 Guide
Why the “right” case size changes everything
A beautiful case protects, enhances, and prolongs the pleasure. The "right" one isn't just a matter of "it fits / it doesn't fit." It fits the diameter (ring gauge), respects the length, avoids pressure points that mark the wrapper, and maintains a stable microclimate when you travel. A case that's too narrow compresses and can crack; too wide, it lets the cigar wiggle and increases the risk of shocks. This guide gives you a simple method for measuring , comparing , and choosing the perfectly compatible case—whether you're a fan of an evening Robusto or a ceremonial Churchill.
The basics: length & ring gauge (diameter)
The size of a cigar is read in two values:
- Length (in inches or millimeters)
- Ring gauge (diameter expressed in sixty-fourths of an inch)
Concretely, 1 ring = 1/64 of an inch . A “50 ring” cigar is therefore 50/64 of an inch in diameter (≈ 19.8 mm). This convention is universal in the cigar world and allows you to easily convert to the metric system.
Practical formula
Diameter (mm) ≈ Ring × 25.4 / 64
Example : a 52 ring ≈ 52 × 25.4 / 64 ≈ 20.6 mm . This allows you to estimate whether a given case (or internal housing) will accept your regular format. Tip: a caliper (or a simple flexible ruler) is enough to quickly check the actual diameter of a module.
The most common formats (and what they mean for the case)
The names (corona, robusto, toro, churchill, etc.) are comfort standards , not laws set in stone. They give an order of magnitude of length and ring gauge:
- Small Corona : ~4½” × 40–42 (≈ 114 mm × 15.9–16.7 mm)
- Corona : ~5½–6” × 42–44
- Robusto : ~4 ¾–5½ “ × 48–52 (≈ 120–140 mm × 19–20.6 mm)
- Toro : ~6–6¼” × 50–54
- Churchill : ~7” × 47 (≈ 178 mm × 18.7 mm)
- Gordo / 60 : ~ 4½–6 “ × 58–60 (thick!)
- Lonsdale / Panetela : thinner, longer
- Figurados (Torpedo, Perfecto) : variable diameters depending on the sections
These ranges are for guidance only: each cigar may vary depending on the brand. Use these limits to anticipate the tolerance required in the case (especially the head height).
How to Accurately Measure Your Cigar (At Home)
- Length : Place the cigar on a ruler, measure from the ring to the foot (not including any torpedo cap).
- Diameter : Place a caliper loosely; read in mm, then convert to ring if necessary (formula above).
- Comfort Guard : Add +1 to +2 mm of play in the case pocket to prevent compression due to humidity variations.
- Figurative case : remember the maximum diameter (the belly) to check compatibility.
Choose your type of case according to use
- Urban elegance : 1 or 2 cigar leather case , slim profile, for an everyday robusto/corona.
- Evening / gift : 2-3 cigar case to match the belt or shoes (brown, black or exotic shades).
- Business trip / weekend : travel case with rigid compartments + accessory pocket (cutter, lighter, humidipack).
- Large modules (54–60 ring) : choose cases with adjustable caps or oversized housings .

Case vs. Tube: Which to Choose?
- Metal tube : maximum protection against shocks, practical for carrying 1 cigar in a pocket. Can create a more humid micro-climate if you add a humidipack .
- Leather case : overall protection, aesthetic and durable, accepts several cigars and better preserves the wrappers thanks to controlled flexibility .
- Hard case : “Daily carry” solution for enthusiasts: machined compartments, waterproof seals , accessory space. Ideal with a 65–69% RH humidification bag (according to preference).
Humidity, temperature and materials: the points that make the difference
To maintain the flexibility of the wrappers and a regular draw during transport, aim for a microclimate of 65–72% RH (at a mild temperature). Below this: drier cigar, burns quickly, and aromas tend towards harshness. Above this: risks of poor combustion and mold if the excess continues. In practice, the "pleasure zone" for many enthusiasts is between 65% and 70% RH (a question of style and origin of the cigars).
When it comes to materials, Spanish cedar remains the king of species: it stabilizes humidity , releases a subtle fragrance that enhances aromas , and helps deter tobacco beetles , insects capable of ravaging a collection. It is used in cellars, but is also found as a filling for high-end cases .
Express method to choose the ideal case (step by step)
- Identify your 2–3 smokiest formats (e.g. Robusto 50, Toro 52, Churchill).
- Measure a sample (length + actual diameter).
- Check the margin of the targeted case (+1/2 mm on the diameter, +5 mm on the length).
- Anticipate use : 1, 2 or 3 cigars? accessories? plane?
- Choose an adjustable head if you alternate between Robusto and Toro (length variations).
- Add a 65–69% humidipack if transporting > 4 h.
- Test empty : insert a template (calibrated roll of paper) to check the space, then test with a cigar under a protective ring.
Plane, train, wedding: three scenarios and our recommendations
- City break & airplane (cabin): Choose a 3-5 cigar travel case (52-54 ring gauge), proper seals, and a cigar cutter slot. Cigars travel better in the cabin (more stable temperature and pressure). Add a humidipack (65-69%) and slip your accessories into the zippered pocket.
- 24–48 hour business trip
- Leather case for 2-3 cigars : (M/L) + straight cut. If you like 58-60 ring gauges, choose an XL that is clearly marked as compatible with 60 ring gauges.
- Weddings & special occasions: Prepare a Robusto/Churchill mix : a 2-3 cigar "L" case will cover most cigar-loving guests, while still looking chic in photos. As a gift, have the initials and date engraved—a guaranteed high-end effect.
Caring for a high-end leather case
- Hydration of the leather (1–2×/year) with a suitable, very light milk.
- Natural drying in case of humidity (never on a radiator).
- Store in a cotton cover when not in use.
- Rotate Cigars: Avoid leaving the exact same area under pressure for weeks.
Three Common Mistakes (and How to Avoid Them)
- Choose wisely : a 52 robusto is “fine” today, but a 54 tomorrow? Allow for some tolerance .
- Forget the length : many failures come from Churchills (≈ 178 mm). Always measure.
- Compact in bulk : the capes are marked. Use dividers or dedicated housings.
Our recommendations by profile
- Demanding beginner : Leather case for 1–2 cigars M (up to 52 ring). Ideal combo with a Robusto .
- Versatile Amateur : 3 cigar case M/L with adjustable head (Robusto/Toro).
- Large module aficionado : XL case compatible with 60 rings (or multi-slot rigid case).
- Traveler : Origin Travel Set – Complete Set (with straight cutter, V, punch, stand, analog hygrometer, 69% humidifier).
- Premium gift : engraved leather (initials, date), matching box, personal card.
Ultra-practical recap
- Ring = 1/64” ; convert to mm to check compatibility.
- Keep +1 to +2 mm margin on the diameter and +5 mm on the length.
- Aim for 65–72% RH , mild temperature, humidipack on the go.
- Spanish Cedar = stability + aromas + beetle deterrent.
Mini-FAQ
What is the formula to convert ring gauge to millimeters?
Ring × 25.4 / 64 = diameter in mm. Example: 52 ring ≈ 20.6 mm.
Does a Toro 54 fit in a “Robusto” case?
Not guaranteed: check the diameter margin (54 ring ≈ 21.4 mm) and the length (a Toro is longer). Prefer an M/L case with an adjustable head.
Can I mix sizes in the same 3-cigar case?
Yes, if each slot provides the necessary clearance for the largest module. Place the largest module in the center to limit lateral pressure.
What humidity level should I aim for during transport?
Between 65 and 70% RH is suitable for most hobbyists. Above 72%, the risk of erratic combustion increases.
Is Spanish cedar useful in a case?
Yes, for its hygroscopic balance properties and its repellent effect on beetles.
