CHAPTER 2: Setting Up Your Monitor

Ergonomic guidelines
The recommended screen positioning is based upon the
following guidelines. These guidelines are based on available
scientific literature and published standards.
Screen height
The recommended screen height for displays (except in special
circumstances, such as for bifocal use) is that the top of the
display should be set at or slightly below (about 1 inch or
25 mm) your eye level while you are sitting in a comfortable
working posture. This guideline places the center of the screen
at an ideal 15° to 20° viewing angle for most desktop displays.
If the display has multiple users, the screen height should be
easily adjustable to accommodate each user’s height and
preference.
Screen tilt
The screen should be tilted so your line of sight is
perpendicular to the screen. This angle creates the most
consistent viewing distance when scanning from the top of the
screen to the bottom. You may need to adjust lighting to avoid
screen glare when the screen is tilted upward.
Screen distance from user
The screen should first be placed at arm’s length from the user,
then adjusted back and forth to suit individual preference.
