Projector screen size calculator
A projector is quoted by its throw ratio: the distance from the lens to the wall, divided by the width of the picture it makes there. Give it that and one measurement, and this gives you the other — drawn on the wall at true scale.
What do you want to work out?
On the projector's spec sheet — distance divided by image width. A short-throw is under 1.

A projected image has no bezel, so the wall only has to hold the picture. For a television in the same room — the TV size calculator.
