Projector throw calculator

Distance = throw ratio × image width. Enter the ratio from the spec sheet (one value for a fixed lens, two for a zoom), then the image size and shape. Distances are measured from the lens to the screen.

Set to the IN5009's 0.79–7.02:1 zoom.

Throw ratio, shortest

Throw ratio, longest

Image diagonal

inches

Screen shape

Enter a throw ratio between 0.1 and 5 and a diagonal between 20 and 400 inches.

Or start from the distance

With the same lens and screen shape, how large an image does a given lens-to-screen distance give?

Lens to screen

metres

Enter a distance above zero.

The plan above is to scale. Real lenses are not perfectly linear, so check the projection-distance table on the data sheet when the fit is tight.
