Image width = Distance / Ratio
Ratio = Distance / Image width
Glossary
F-STOP
f stands for 'focal length' (Brennweite). Ratio of focal length to 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.
THROW RATIO
Also called projection ratio, ratio, or throw. It expresses the relationship between the throw distance and the image width. Multiplying the ratio by the image width yields 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.
IMAGE SIZE (Diagonal)
Distance between two diagonally opposite corners.
ASPECT RATIO
Aspect ratio, the relationship of width to height
IMAGE RESOLUTION
Number of picture elements (pixels) of the width and height of an image: e.g. 1920×1080
