How much bigger is an IMAX frame than a standard film frame?
About ten times the area of a standard 35 millimeter frame, because IMAX runs 70 millimeter film horizontally through the camera and projector.
An IMAX frame, exposed on 70 millimeter film run horizontally through the camera and projector rather than vertically, captures roughly ten times the image area of a standard 35 millimeter film frame.
