Cigar Ring Gauges Explained
Ever wonder what the ring gauges mean and what size it really is? What does a 42, 50, 52 ring gauge actually mean. What size is a Corona, or a Robusto...
Hopefully this post will shed a bit more light on it.
Ring Gauges of Cigars
The ring gauge of the cigar relates to the diameter measured in inches. So for example a Double Corona with a ring gauge of 50 has a diameter of 50/64th of an inch.
Being in New Zealand, and not working with inches, this doesn't tell me an awful lot, so here is a table that shows the ring gauges in centimetres.
| Ring Gauge | mm |
| 1/4 | 6.3500 |
| 17/64 | 6.7469 |
| 19/64 | 7.5406 |
| 21/64 | 8.3344 |
| 23/64 | 9.1281 |
| 25/64 | 9.9219 |
| 27/64 | 10.7156 |
| 29/64 | 11.5094 |
| 31/64 | 12.3031 |
| 33/64 | 13.0969 |
| 35/64 | 13.8906 |
| 37/64 | 14.6844 |
| 39/64 | 15.4781 |
| 41/64 | 16.2719 PETIT CORONA (129mm long) |
| 43/64 | 17.0656 CORONA (142mm long) LONSDALE (165mm Long) |

| 49/64 | 19.4469 ROBUSTO (124mm long) |
| 51/64 | 20.2406 DOUBLE CORONA (194mm long) |
| 53/64 | 21.0344 BELICOSO (140mm long) |
| 55/64 | 21.8281 |
| 57/64 | 22.6219 |
| 59/64 | 23.4156 |
| 61/64 | 24.2094 |
| 63/64 | 25.0031 |
| 64/64 | 25.4000 |
* some cigars like Torpedos, Pyramids and Figurados will differ in diameter from top to foot.
* as the ring gauges are all odds, most cigars have an 'even' number. eg a corona is 42 ring gauge.
The different names and sizes are averages. Different manufacturers have different sizes. Coronas, Churchills, Robustos are generic names with the sizes above being the most common.
Hopefully you have found this helpful. The next step is to name the different cigars, the lengths, the names, eg Robustos, Coronas, Rothschild, Churchills, Panatellas, Short Churchills, etc. These names relate to the sizes of cigars and usually have an interesting history behind them.
