I am trying to make a little tool for myself to compare viewfinder sizes. I do get some results but the rectangles seem to be a bit small I think. Probably interpreting some values wrong. Can someone please have a look?
The colors in red are the 6D's sensor size, magnification, viewfinder coverage and aspect ratio respectively.
magni = ((35,8 mm * 23,9 mm) = 855,62 mm2) * .71x = 607,4902 mm2
surface = (magni * 97%) = 589,265494 mm2
edge = sqrt(surface) = 24,274791327630398396804364790437 mm) * 2 = 48,549582655260796793608729580875 mm
aspec_part = edge / (3 + 2) = 9,7099165310521593587217459161749 mm
width = aspec_part * 3 = 29,129749593156478076165237748525 mm
height = aspec_part * 2 = 19,41983306210431871744349183235 mm
width_px =(width * 0,0393700787) = 1,1468405339938635232734500043636 inch * 72 dpi = 83px
height_px = (height * 0,0393700787) = 0,76456035599590901551563333624242 inch * 72 dpi = 55px
Below are the results I get.
