A:Answer My screen is just 100 inches, my projector is 8 and a half feet from screen. I have no doubt this projector will do a screen as big as a double garage door, and if you have never seen an Epson in use, oh my gosh, the picture is so colorful and clear as a large flat screen TV, and no glare from a glass screen, like if you happen to have a small light on in the room. I love this projector,
