Okay so I think we are all a little confused here (maybe it's still just me lol) the viewfinder that I have is for a 35mm rangefinder that doesn't have frame lines for differnet focal length lenses. The viewfinder can be set to 35mm, 50mm, 90mm, 135mm, and has spaces in between for intermediate focal distances.

So what I am trying to figure out is what setting on the viewfinder is closest to what this pinhole will be according to the dimensions from my original post (taking into consideration I will be using 120 (6x9) instead of 35mm film.

Maybe I'm overthinking this a little but I just want to have a general idea of what I will be taking a picture of and I figured the viewfinder would help tremendously.
