What are the screen sizes of IMAX, cinema compared to home projectors? (1 Viewer)

[JediFonger]

i've been googling. are the following figures somewhat correct?

in feet:
IMAX screen size=65'x85' (107' diagonally)
AMC/Showcase screen size (largest auditorium)=27'x46' (53' diagonally)
my home front projected screen size=6'x7' (it's about 9', but i only do 7.5' diagonally)

in inches:
IMAX screen size=780"x1020" (1,284" diagonally)
AMC/Showcase screen size (largest auditorium)=324"x552" (636" diagonally)
my home front projected screen size=72"x84" (it's about 100", but i only do 90" diagonally)

The Imax theater in Jakarta used to be the biggest, and I think it was sort of ~80' high, but don't quote me on that.

The rest of the numbers look reasonable - I do about a 70" diagonal at home, myself.

Ahh, but what are the viewing angles of each screen? It is conceiveable that your HT screen could 'appear' larger...

Clearly, someone who's never been to an IMAX theatre.

Eh, you can do it in the HT environment; the problem is that when you're a foot off of the screen, you've the unexpected difference of having to actually change the focus and convergence of the eye - something that one doesn't normally have to do in an Imax or conventionally viewed HT space.
