Use the possibilities of On-line Projection Size/Distance Calculators offered by the digital projection equipment manufacturers, whose products Firm Alpha CO., LTD has honor to officially represent on the local and regional markets

A Projection Size/Distance Calculator is an effective tool to determine:

• How far away from your projection screen you will need to place your projector. Calculate the max/min projection distance by desired screen size (width x height or diagonal)
• What size screen you will require. Calculate the screen size (width "x" height or diagonal) by known projection distance. Please note - this calculation depends on your projector model and how far you will position your projector away from the screen.
• Which optional lens (if your projector has this option) you may need to provide the required size screen and projection distance.

While using Projection Size/Distance Calculator please note that a list of offered to your attention digital projectors and lenses may in many cases include EOL (discontinued) models.
