Viewing Distance

Recommended viewing distance between the eye and the monitor : 1.5x diagonal of screen

The optimal viewing distance partly depends on the quality of
the image (contrast, resolution, brightness, etc.) and on the
user’s visual acuity. However, the greatest factors in determining
the optimal viewing distance are the horizontal viewing angle
and the size of the characters (character height) on the screen.
This also means that there is a direct correlation between the
horizontal viewing distance and the size of the computer screens.

Moving the screen further from the viewer, however, also means
that the characters on the screen will have to be enlarged
proportionally. The disadvantage of doing this, is that less
information fits on the screen which results in more scrolling

 

According to NEN 894-2, the optimal viewing angle lies
between 0 and 15º and 0 and -15º (area A). The acceptable
viewing angle lies between 0 and 30º and 0 and -30º (area B).
Area C is not easily visible anymore. As a result, users will have
to turn their head to get a good view of it (see Figure 3).source
