The chimney is not yet built.

If it's a prefab, I would stick to 6". *The chimney should be the size
of the stovepipe.
If it's a masonry chimney, the only reason to go bigger (7") is if you
want to more easily reline the chimney further down the road.. *But, a
bigger chimney will create more draft, thus a little more heat lost to
the exterior.

I just installed a new woodstove in my home that came with a 6"
stovepipe exhaust. *We had a 7" brick chimney built for it. *It works
fine. I wanted a chimney that could be relined easily (in ~30 so years).

Thanks.
This is for a small (20x24') cabin with loft. *I'm thinking of a prefab
metal chimney out the exterior wall. *I know this is perhaps not the best
arrangement but I prefer not to punch a hole in the new roof. *

Bad choice, poor draft and drainage problems. A roof isn't sacred, and
a prefeb near the peak will be perfect for your installation. Follow
code for height, use the right flashing exactly like the directions
(under the shingles upstream and over the shingles downstream) and
install a storm collar. The only real trick part is cutting the
elliptical hole so the pipe is nice and straight going through the
roof. HTH
