How do I find the right value?

Distance = image width x Ratio
Image width = Distance / Ratio
Ratio = Distance / image width

Glossary

f-Number
f stands for 'focal length'. The ratio of focal length to aperture. Zoom lenses often have two values. The larger apertures are described with small numbers and the smaller apertures with large numbers. A lens with a lower f-number lets more light through.

THROW RATIO
Also known as projection ratio or throw ratio. It indicates the ratio of the projection distance to the image width. Multiplying the number by the screen width gives the distance between the projector and the screen. Therefore the screen width can be calculated by dividing the throw 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 adjusted within the specified range.

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

ASPECT RATIO
Aspect ratio, the ratio of width to height

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