I guess you'll have to solicit measurements from people who own pots you think are close.
The wall thickness is no more than 1/8" so a published interior can have 1/4" added to it to get to a max.
The handle brackets are another issue entirely, I don't think my oilcan mug would even fit without some modification to this thing to clear handles.
I plan to just make it simple and use a wider pot, with some manner to hold the pot off the top 1/2" or so. With a stoker hole. This will be a pair of snips and test kind of stove, at $3 invested, that's the amount of planning I intend to put in. Stove rides inside of pot when stored (yes, my pot will get ashy, I'll survive).
Edit: I picked up one of each today, here's the measurements. 4 1/2" exactly inside clear. The top has a 1/8" roll on it.
The weight of the 5 1/8" high is 4.64oz. The 7" high is 6.16oz.
