37:20 Diagonal ÷ 1.135 = Width Width ÷ 1.85 = Height

CINEMASCOPE FORMAT
 47:20 Diagonal ÷ 2.55 = Height Width ÷ 2.35 = Height

The height of the screen should approximately be one sixth of its destance to the last row of seats. The distance between the screen and the first row of seats should be about twice the height of the screen. The minimum distance between the screen bottom and the floor should be about 1.25 m if the audience is sitting resp. 1.60 m if the audience is stanmding.
