Why calculate your humidor's capacity?
Knowing exactly how many cigars can fit in your humidor is essential for smart investing. An underutilized humidor struggles to maintain stable humidity — while an overloaded one prevents air circulation and compromises the preservation of your Havanas.
Whether you store Cohiba Robustos, Montecristo No. 2s, or Partagas Serie Ds, dimensions vary significantly from one format to another. Our tool automatically calculates the cylindrical volume of each cigar and applies it to your available space.
Optimize your storage, plan your upcoming purchases, and choose your next humidor with full knowledge — whether it’s a travel case, a desktop box, or a large-capacity collector’s cabinet. To complete your ritual, also discover our cigar cutters and cigar lighters.
FAQ
Everything about capacity calculation
Calculation method, margin to plan for, formats covered: answers to our most frequently asked questions.
How is a humidor's capacity calculated?
The capacity is estimated by dividing the humidor's internal volume (Width × Depth × Height in mm³) by the cylindrical volume of a cigar (π × (diameter/2)² × length). A stacking coefficient of 0.59 is applied to account for the unavoidable empty spaces between cigars. This calculation provides a reliable theoretical estimate to compare formats and plan your collection.
Should I leave empty space in the humidor?
Yes — it is recommended never to exceed 80 to 90% of the theoretical capacity. Optimal humidity circulation is essential to maintain stable hygrometry between 65% and 72%. An overfilled humidor creates dry spots and overly humid areas, which alter the quality and taste of your cigars over the long term.
Does this calculator work for all cigar formats?
Yes. It covers the most common formats from major brands (Cohiba, Montecristo, Partagas, Romeo y Julieta, Davidoff, Arturo Fuente, etc.). The calculation method is universal — it applies just as well to a small Panetela as to a Double Corona, provided you know the cigar's length and diameter.
Can I use it for a travel humidor?
Absolutely. Measure the usable internal dimensions of your case or travel humidor (in millimeters, without unusable areas like rounded corners or dividers). Enter these values and select the cigar format to get an accurate estimate of the number of vitolas you can take with you.
