How big should I make my fire box

I have always heard that the firebox should be at least 1/4 of the volume of the cooking chamber. You have 76,302 cubic inches of cooking chamber, so you would want at least 19,075.5 cubic inches of firebox, or 26.72" x 26.72" x 26.72" for a box shaped firebox or for a pipe shaped firebox you want a 36" pipe at least 18.75 inches long. That pipe firebox sounds kind of "stubby", so you may want to see if you can get a 30 inch pipe that is 27 inches long. If you have to change sizes to make things fit, go up.

But I am not a professional pit builder, so make sure you get another opinion. I'm basing this on the information I have gained from hearing this question asked before.

But I did stay at a Holiday Inn Express last night if that means anything...

Make sure the firebox is at least 24" long regardless of shape so you won't have trouble making your wood fit.

We all know what a pain that can be if your wood doesn't fit in the box.

I would agree with the 24 inch minimum with one addition. Assuming that you are going to make a square box I would go to 26x26 and install a 24x24 insert liner on the inside. You say that you want to cook all year round and a big factor in the rain or cold is loosing your heat. The liner will solve some of that problem.

I bend the two ends at a 90 degree x 1 inch, and put 4 small steel bolts in place to hold the side from moving. Do this on 5 sides. Now you have a 1 inch liner in place.
