11.3.1.2-2 Horizontal Viewing Angle

The horizontal viewing angle from the eye point of the user to the center of the visual display image area should be in the range between a minimum of minus 35 degrees and a maximum of plus 35 degrees, measured in the horizontal plane relative to direct, frontal perpendicular viewing.

Additional Information: The preferred horizontal viewing angle is in the range between a minimum of minus 15 degrees and a maximum of plus 15 degrees. For workstations with multiple visual display screens arrayed in the horizontal dimension, this horizontal viewing angle may be expanded to a range between minus 60 degrees and plus 60 degrees for tasks where head rotation is allowed. 100, 1472G
