Manufacturers use their own cigar sizes and rarely specify which size they’re referring to. The only measurement you can use to compare humidors is the internal volume in liters. As a rule of thumb, four Robustos fit into one liter of humidor capacity: a 150-liter humidor can hold approximately 600 Robustos.
In this article, you’ll learn why only 4 Robustos fit in one liter, why the stated numbers vary so widely, how to do the math yourself, and what it costs to store one liter in the humidors we sell.
A Petit Corona (ring gauge 42, 129 mm) takes up less than half the space of a Churchill (ring gauge 47, 178 mm) or a Gordo (ring gauge 60). A manufacturer who bases their calculations on small sizes will therefore arrive at a much higher number than a manufacturer who bases their calculations on Robusto. In addition, one manufacturer counts individual cigars on tightly packed shelves, while the other takes into account the air between the cigars and the space occupied by drawers and shelves.
The result: two cabinets with the same interior dimensions can have a stated capacity that differs by a factor of two. Anyone who compares them based on the number of cigars is comparing the calculation method, not the cabinet itself.
We use four Robusto long-filler cigars per liter for all the brands we carry. The manufacturers themselves use a more generous calculation: Raching lists 500 to 600 cigars for the MON800A (150 liters, or 3.3 to 4 per liter) and 3,000 to 4,000 (580 liters, or 5 to 7 per liter). This difference stems from the size used in the calculations. That is why our product pages list the number of Robusto cigars for each humidor according to the same standard, alongside the internal volume.
A Robusto (ring gauge 50, 124 mm) has a volume of 38 cm³. A box with a capacity of exactly one liter can hold twenty cigars when stacked tightly. A 150-liter cabinet is not a box: its internal volume includes the space between the shelves, the drawers, and their walls, the space for air circulation, and the air above and beside the cigars. Furthermore, you store cigars in boxes or in loose rows, not tightly stacked all the way to the door. In practice, about one-fifth of the interior space remains available for the cigars themselves, which works out to four per liter. That corresponds to the lower end of what Raching specifies for its smaller models.
The price per liter shows how much storage space you get per euro. The table below lists Raching’s temperature-controlled models, with prices including VAT as of November 2026.
| Model | Internal volume | Robusto (4 per liter) | Price | Price per liter |
|---|---|---|---|---|
| Raching C380A | 380 L | approx. 1,520 | €2,550 | €6.71 |
| Raching MON5800A | 580 L | approx. 2,320 | €4,470 | €7.71 |
| Raching CT48A | 450 L | approx. 1,800 | €4,343 | €9.65 |
| Raching C150A | 150 L | approx. 600 | €1,499 | €9.99 |
| Raching MON3800A | 380 L | approx. 1,520 | €3,799 | €10.00 |
| Raching MON1800A | 230 L | approx. 920 | €2,990 | €13.00 |
| Raching MA50 | 100 L | approx. 400 | €1,300 | €13.00 |
| Raching MON800A | 150 L | approx. 600 | €2,140 | €14.27 |
Large cabinets are cheaper per liter than small ones. The C380A and the MON5800A offer the most storage per euro. For the same size, the MON series costs more per liter than the C series because it features water cooling and ammonia removal.
For cabinets with exteriors made of leather, canvas, or handmade veneer, you’re paying for the furniture, not for storage space. Such cabinets cost two to eight times as much per liter as a functional cabinet of the same size. That’s a conscious choice for style. If you’re primarily looking for space for your collection, compare cabinets based on liters and price per liter.
Count the average number of cigars you have at home and add half that number to account for growth. Divide by four, and you’ll have the number of liters you need. If you store 300 cigars, you’ll need about 115 liters: the Raching C150A or the MON800A. If you store 1,000 cigars, you’ll need about 375 liters: the C380A or the MON3800A.
How many cigars fit in one liter?
About four Robusto cigars (ring gauge 50, 124 mm) per liter of humidor capacity. A tightly packed one-liter box holds twenty, but in a humidor, most of the interior space is taken up by shelves, drawers, air circulation, and the boxes themselves. For smaller sizes, such as a Corona, more will fit; for larger sizes, such as a Churchill or Gordo, fewer will fit. Four per liter is the standard we use for all brands and models.
Why does one manufacturer produce so many more cigars than another?
This is because manufacturers use different cigar sizes and usually do not specify which size they use. A specification based on small sizes will be much higher. Therefore, compare based on internal volume in liters.
Do drawers and shelves count toward the total volume?
The internal volume is the interior space of the cabinet. Drawers and shelves take up part of that space, which is already factored into the standard of four Robusto cigars per liter.
Can I store cigar boxes in an electric humidor?
Yes. Keep in mind that a box takes up more space than the cigars themselves; so plan on about three cigars per liter.
Is a larger cabinet more expensive to use?
A little, because more air is being cooled. Per liter, a large cabinet is generally more cost-effective to purchase. A half-empty cabinet isn’t a problem, as long as the humidification is working properly.
