How do I find the correct value?

Throw distance = Image width x Ratio
Image width = Throw distance / Ratio
Ratio = Throw distance / Image width

Glossary

f-Value
f stands for focal length (Brennweite). Ratio of the focal length to the aperture. Zoom lenses often have two values. The large apertures are described with small numbers and the small apertures with large numbers. A lens with a lower f-number lets more light through.

IMAGE THROW RATIO
Also projection ratio, called ratio, throw. It is the ratio of the projection distance to the image width. The product of the number with the screen width is the distance between the projector and the screen. Therefore the screen width can be calculated if you divide the screen distance by the ratio. If two numbers are given (e.g., 1.5-2.5:1), this means the projector has a zoom lens and the ratio can be changed within the specified range.

SCREEN SIZE (Diagonal)
Distance between two diagonally opposite corners.

ASPECT RATIO
The aspect ratio that represents the ratio of width to height

IMAGE RESOLUTION
Number of image points (pixels) of the width and height of an image: e.g., 1920×1080
