If a value in a chart does not match the results of the formulas, use the values in the chart. The ceiling must be strong enough to support the projector and the installation must be in accordance with any local building codes. All formulas are based on a 4:3 aspect ratio and screen. Distances are in inches, for millimeters multiply by 25.4. Distances may vary ±5%. Formulas The Projection Formulas use the image width for calculation. Image width is the same for all aspect ratios, only vertical image size varies. For proper projector placement, determine the image width for a desired screen size. Use the Screen Formulas below to calculate all screen dimensions. Plug in the image width for "W" in the Projection Formulas. Refer to the diagrams and charts for popular screen sizes on page 2. Definitions: W = Image Width H = Image Height (Size) B = Vertical distance between lens center and screen center C = Throw distance D = Vertical distance between lens center and screen top (screen bottom for desktop) = Projection angle Projection Formulas: B = 0.2986W C = 1.2008W ­ 1.142 D = 0.0764W = tan-1 (B/C) 4:3 Screen Formulas: W = H x 4/3 H = W x 3/4 Screen Diagonal = W x 5/4 www.necvisualsystems.com VT37/47 Page 1 of 6 Diagrams and Distance Charts The following diagrams show the relationship between projector position and the screen.
