Travis,
Asking "how large a pinhole camera I'd need for 16x20 format" is in
essence not different than asking: I have an SLR what lens should I buy?. The
answer is: it depends on the application and/or results you want to achieve.
Having said that, if I was making a 16x20" camera, I'd make it wide angle,
perhaps something equivalent to 75mm to 90mm in 4x5 format (in case you are
familiar with this format), in other words, I'd make it so it has anywhere from
300mm to 360mm in focal length or distance pinhole to film/paper.
You were not asking for pinhole sizes but: As for getting scientific about
pinhole, as Chris was refering to, I don't like optimum pinholes either, but I
do measure the pinholes I make, I'd hate to poke a hole in a metal foil and by
chance get the perfect optimum hole for my camera. By knowing what the "perfect
optimum" hole is and by measuring my pinholes, I can not only know the f/stop of
my camera but equally important I can make sure I avoid using the perfect
optimum pinhole!!
