Calculating the Projected
Image Size
The screen diagonal dimension
can be approximated by using one
of these formulas:
Zoomed out
7.5*Distance(ft.)=Diagonal(in.)
0.625*Distance(m)=Diagonal(m)
or
Zoomed in
6.25*Distance(ft.)=Diagonal(in.)
0.52*Distance(m)=Diagonal(m)
For example:
If your xb31 is 10 feet from the
screen, the approximate zoomed
out screen diagonal dimension will
be 7.5*10 = 75 inches. Zoom Ring
