(All values obtained using the formula below are approximate and may differslightly from the actual values.)Screen aspect ratio 16:9 Screen aspect ratio 4:3Projection screen height (SH) = SD (m) x 0.490 = SD (m) x 0.6Projection screen width (SW) = SD (m) x 0.872 = SD (m) x 0.8Minimum projection distance (LW) = SD (m) x 1.1503 - 0.056 = SD (m) x 1.4098 - 0.053Maximum projection distance (LT) = SD (m) x 2.2951 - 0.041 = SD (m) x 2.8106 - 0.037
