Projector Screen Size Calculator

Please Note:

Calculations are for reference only. Accuracy is believed to be +/-5%

Enter your throw ratio and your projection distance.

If you know the zoom on the lens you may enter a min. and max for the throw ratio.

Example: The Manufacturer provides only one Throw Ratio at 1.58 but states the zoom to be 1.2.

The min Throw Ratio would be 1.58 and the max throw ration would be 1.58 x 1.2 = 1.896

Important: Throw Ratio = Distance/Width

Manufacturers specs vary in their presentation of the Throw Ratio.

You may want to consult your manual to verify that the throw ration is stated as Distance/Width.

Where possible we recommend using the MFG projection calculators.
