How ring gauge works
Ring gauge is a cigar's diameter in sixty-fourths of an inch. A 50 ring is 50/64 of an inch, which is about 19.8 mm. The formula: millimetres = ring gauge ÷ 64 × 25.4, and back again ring gauge = millimetres ÷ 25.4 × 64.
Cuban and European shops often give sizes in millimetres (for example 124 × 50), American shops in inches (4⅞ × 50). The ring gauge is the same number in both.
For what each size means for flavor and smoking time, read cigar sizes and ring gauge explained.
