EPSON PowerLite 9300i Projector Distance and Screen Size Calculations Use the calculations below to determine the how far to place the projector from the screen and the size of the screen. Standard Zoom Lens (V12H004S02) To find the distance when you know the screen's diagonal size: ❏ Distance at Wide setting (inches) = (diagonal screen size [inches] × 3.7857 - 9.6813)/2.54 ❏ Distance at Tele setting (inches) = (diagonal screen size [inches] × 5.175 - 9.5418)/2.54 To find a screen's diagonal size when you know the distance: ❏ Screen size at Wide setting (inches) = (projection distance [inches] × 0.264152 × 2.54) + 2.557334 ❏ Screen size at Tele setting (inches) = (projection distance [inches] × 0.193237 × 2.54) + 1.843826 Rear Projection Wide Lens (V12H004R02) To find the distance when you know the screen's diagonal size: ❏ Distance (inches) = (diagonal screen size [inches] × 1.81553 - 6.59805)/2.54 To find a screen's diagonal size when you know the distance: ❏ Screen size (inches) = projection distance [inches] × 2.54 × 0.5508024 + 3.634232 Wide Zoom Lens (V12H004W02) To find the distance when you know the screen's diagonal size: ❏ Distance at Wide setting (inches) = (diagonal screen size [inches] × 2.68681 - 6.80456)/2.54 ❏ Distance at Tele setting (inches) = (diagonal screen size [inches] × 3.80739 - 6.46563)/2.54 To find a screen's diagonal size when you know the distance: ❏ Screen size at Wide setting (inches) = (projection distance [inches] × 2.54 × 0.372189 + 2.53258) ❏ Screen size at Tele setting (inches) = (projection distance [inches] × 2.54 × 0.262647 + 1.698179) Middle Throw Zoom Lens (V12H004M01) To find the distance when you know the screen's diagonal size: ❏ Distance at Wide setting (inches) = (diagonal screen size [inches] × 5.02466 - 13.5124)/2.54 ❏ Distance at Tele setting (inches) = (diagonal screen size [inches] × 7.6049 - 13.3501)/2.54 To find a screen's diagonal size when you know the distance: ❏ Screen size at Wide setting (inches) = (projection distance [inches] × 2.54 × 0.199018 + 2.689217) ❏ Screen size at Tele setting (inches) = (projection distance [inches] × 2.54 × 0.131494 + 1.75546) Middle Throw Zoom Lens (V12H004M02) To find the distance when you know the screen's diagonal size: ❏ Distance at Wide setting (inches) = (diagonal screen size [inches] × 7.409 - 14.5823)/2.54 ❏ Distance at Tele setting (inches) = (diagonal screen size [inches] × 11.2032 - 14.8525)/2.54 To find a screen's diagonal size when you know the distance: ❏ Screen size at Wide setting (inches) = (projection distance [inches] × 2.54 × 0.134971 + 1.968187) ❏ Screen size at Tele setting (inches) = (projection distance [inches] × 2.54 × 0.08926 + 1.323702) Long Throw Zoom Lens (V12H004L04) To find the distance when you know the screen's diagonal size: ❏ Distance at Wide setting (inches) = (diagonal screen size [inches] × 10.6703 +14.1243)/2.54 ❏ Distance at Tele setting (inches) = (diagonal screen size [inches] × 14.407 + 13.343)/2.54 To find a screen's diagonal size when you know the distance: ❏ Screen size at Wide setting (inches) = (projection distance [inches] × 2.54 × 0.093718 1.323702) ❏ Screen size at Tele setting (inches) = (projection distance [inches] × 2.54 × 0.069411 0.926168) 4 - EPSON PowerLite 9300i Projector 10/03
