Start with two measurements: cigar length and diameter. Capacity alone does not confirm fit. A case is right when its usable length and opening diameter are both larger than the biggest cigar you carry, with a little tolerance to spare.
Step 1: Measure the cigars you actually carry
Write down the length and ring gauge of the largest cigar you carry regularly, not the largest you own. Length is usually given in inches on the box; multiply by 25.4 to get millimeters. Ring gauge is diameter in 64ths of an inch; multiply by 25.4 and divide by 64 to get millimeters, or use the ring gauge converter. A 6 × 52 toro is 152 mm long and 20.6 mm across.
Quick reference
| Ring gauge | Approx. diameter | What to check |
|---|---|---|
| 42 | 16.7 mm | Fits most narrow individual channels |
| 46 | 18.3 mm | Comfortable in 20 mm channels |
| 50 | 19.8 mm | Common robusto width; needs 21 mm or wider |
| 52 | 20.6 mm | Confirm channels of at least 22 mm |
| 54 | 21.4 mm | Look for 23 mm or wider channels |
| 56 | 22.2 mm | Many compact channels become tight; 23.5 mm+ |
| 60 | 23.8 mm | Requires an explicitly wide opening, 25 mm+ |

| Robusto | 5 × 50 | 127 mm | 19.8 mm |
| Belicoso | 5½ × 52 | 140 mm | 20.6 mm |
| Toro | 6 × 50 | 152 mm | 19.8 mm |
| Gordo | 6 × 60 | 152 mm | 23.8 mm |
| Churchill | 7 × 47 | 178 mm | 18.7 mm |
| Lancero | 7½ × 38 | 190 mm | 15.1 mm |
| Double corona | 7⅝ × 49 | 194 mm | 19.4 mm |
Step 2: Read the case specifications
Product pages list several kinds of dimension, and they answer different questions:
- Exterior size (length × width × thickness) tells you how the closed case packs. It is not the usable interior length; allow 10–15 mm for the shell and lining if no interior figure is given.
- Maximum cigar length, slot length, or compatible length is the figure to compare with your cigar’s length.
- Opening, channel width, slot width, or maximum diameter is the figure to compare with your cigar’s diameter. Some makers state it as a ring gauge instead.
- Package size describes the gift box and matters only for shipping and wrapping.
Step 3: Leave tolerance
A cigar that exactly matches a limit is a tight fit. Makers hand-measure their products, lining takes up space, and cigars themselves vary slightly from their nominal size. Aim for at least 1 mm of clearance on diameter and 5 mm on length. Box-pressed cigars are wider across the flat than their ring gauge implies, so give them 2 mm.

Step 4: Choose capacity from real use
Buy for the number of cigars you normally carry plus one, not for the largest trip you can imagine. A half-empty case lets cigars move, and a bigger case takes more bag space every day. One- to three-cigar cases fit a pocket; four- and five-cigar cases belong in a bag; eight-cigar travel humidors are luggage.
Check your numbers
Use the case fit checker to compare a specific cigar with a specific case, and the travel case selector for a starting category. If a product page does not state the figure you need, ask us and we will confirm it where possible.
