What BTU does a smoker need?

A general rule: 1 BTU per cubic inch of cooking chamber per hour. A 3,000 cubic inch smoker (17x17x10 cooking chamber) needs roughly 3,000 BTU/hr at 225°F smoking temperature.

What is the firebox to cooking chamber ratio?

The standard recommendation is a 1:3 firebox-to-cooking-chamber ratio by volume. A well-designed firebox and stack creates natural draft maintaining even temperatures.
