The honest answer is: it depends on the size of the humidor and the size of your cigars. As a quick guide, a desk humidor typically holds anywhere from 20 to 100 cigars, a cabinet humidor holds several hundred, and a walk-in room holds thousands. But a 100-cigar humidor rarely holds exactly 100 in real life, and this guide explains why, so you buy the right size the first time.
How humidor capacity is measured
Stated capacities almost always assume two things: the box is full to the brim, and the cigars are a modest ring gauge, usually a Robusto or a Corona. Change either and the number moves. It is a headline figure, not a promise, which is why the same humidor can be described as holding 80 or 120 cigars depending on the cigar used as the yardstick.
Why ring gauge changes everything
A cigar's ring gauge is its diameter in 64ths of an inch. A slim Corona (ring 42) takes far less room than a thick Toro (ring 50) or a chunky Gordo (ring 60). Two humidors of identical volume can hold very different counts simply because of the cigars inside. That is why we quote our humidors in Toro as a realistic, modern reference, with the Robusto figure alongside, rather than a flattering best case.
Single layer versus stacked layers
Capacity also depends on format. A shallow drawer holds a single layer, while a deep chest holds cigars stacked in layers, which multiplies the count for a similar footprint. It is the reason our chest-format Snake, with a smaller footprint than a desk Diamond, still holds up to 100 cigars.
Real-world capacity: leave room to breathe
Two practical truths from experienced collectors:
- Most people do not pack a humidor to the brim, so real-world capacity is often 20 to 30% below the headline number.
- A humidor that is comfortably filled holds humidity more steadily than one that is nearly empty.
When in doubt, size up. You will grow into it, and it will perform better along the way.
A quick size guide
| Humidor | Realistic capacity |
|---|---|
| Diamond Small (desk) | around 80 Toro (about 90 Robusto) |
| Diamond Large | around 120 Toro (about 135 Robusto) |
| Snake (chest, limited edition) | up to 100 (Corona or Robusto) |
| Bar Cabinet humidor insert | 150+ cigars |
Slim vitolas raise these numbers; Churchills and large ring gauges lower them.
How many Boveda packs for that capacity?
As a rule, use one 320g Boveda pack per roughly 100 cigars of capacity; more packs mean steadier humidity and longer life. Full details are in our Boveda 320g guide. There is no water to add: you simply replace the packs when they stiffen, typically every two to four months.
How to choose the right size
Match the humidor to your habit and leave headroom: count the boxes you keep moving, add what you would like to lay down to age, then choose the size just above that. Consider format too (drawer versus chest) and, at cabinet scale, dynamic circulation for even humidity.

Frequently asked questions
How many cigars does a desk humidor hold?
Typically 20 to 100, depending on the model and ring gauge. Our Diamond Small holds around 80 Toro.
Does ring gauge really change capacity?
Yes, significantly. Slim Coronas fit far more than thick Toros or Gordos in the same space.
Should I buy a bigger humidor than I need?
Usually yes. A comfortably filled humidor holds humidity better, and collections tend to grow.
How many cigars does the Litolite Diamond hold?
Around 80 Toro in the Diamond Small and around 120 Toro in the Diamond Large, shifting with ring gauge.
How many Boveda packs do I need?
About one 320g pack per 100 cigars of capacity.
