    There is a firebox size calculator on the site if you search for it. Probably be some more people chiming in on this

    Welcome. I'm not a builder, but there are a couple of calculators on here that folks use for all the sizes, dimensions and other stuff. However, one thing I've learned is that the FB should be about 30% of the CC. So, I'd say around 40 gallons.

    Good luck. Go to the smoker build section and look or click on the search bar and enter your question.

    My 150 has a 50 gal fire box. Works great! b

     
  5. My 120 FB is a 22" cube.
