I'm looking to convert (2) bar cabinets with glass doors into humidors. The dimensions are approximately 1' wide by 1' deep by 3' tall. Is there a general rule of thumb for how many cigars can be stored in a given space? Or is my best bet to figure the volume of a 100-cigar humidor and use that ratio as a guideline?

I'm planning on lining the cabinet with 3/8" thick Spanish cedar and using Le Veil digital humidification, if that matters.

Any input would be greatly appreciated.
