Quick answer
Walk-in humidors typically need about 1 pint of moisture output per day for every 250-350 cubic feet of well-sealed space.
Output (pints/day) = volume / coverage rate
How to use the Cigar Humidor Calculator
- 1Measure the humidor room's internal dimensions.
- 2Divide the volume by the coverage rate of the humidification device.
- 3Round up to the next available unit size for a margin against door openings.

Frequently asked questions
Why does door traffic matter?
Every opening exchanges humid air for dry room air, so busy humidors need extra output capacity.
Do I need dehumidification too?
Only in humid climates — most humidors need active humidification, not removal.
