Ergonomic guidelines
The recommended mounting heights, the range of adjustability required to
provide comfortable use by a range of users, and the forces required for making
adjustments to the monitor are based upon the following guildelines. These
guidelines are based on available scientific literature and published standards.
Screen height
The recommended screen height for monitors (except in special circumstances,
such as for bifocal use) is that the top of the monitor should be set at or slightly
below (about 1 inch, or 25 mm) the user’s eye level while the user is 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 monitors. If the monitor
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 the user’s 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 monitor screen should first be placed at arms length from the user, then
adjusted back and forth to suit individual preference. Vertical adjustments
should not result in a change in viewing distance.
Stand adjustment forces
The force required to make any adjustment to the stand (height, tilt, pan, or
portrait/landscape orientation) should not exceed 5.1 lbs. (2.32 kg).
