Positioning the monitor
Adjusting the monitor height
Your monitor position should allow your head to be balanced comfortably over your
shoulders. It should not cause your neck to bend forward uncomfortably or backward
to any degree. You may find it more comfortable to position the monitor so that the
top line of text is just below your eye height. Your eyes should look slightly
downward when viewing the middle of the screen.
Many computer designs allow you to place the monitor on top of the system unit.
If this places the monitor too high, you may want to move the monitor to the desktop.
On the other hand, if the monitor sits on your work surface and you feel any
discomfort in your neck or upper back, the monitor may be too low. In that case,
try using a thick book or a monitor stand to raise the monitor.
Tilting the monitor
Tilt the monitor so that it faces your eyes. In general, the monitor screen and your
face should be parallel to each other. To check for correct monitor tilt, have someone
hold a small mirror in the centre of the viewing area. When sitting in your normal
work posture, you should be able to see your eyes in the mirror.

HINT: Eye Height
Your eye height will change considerably, depending on whether you use a reclining or upright posture,
or some posture in between. Remember to adjust your monitor's height and tilt each time your eye
height changes, as you move through your comfort zone.
AVOID! If you look at the monitor more than you look at paper documents, avoid placing your monitor to the
side.
Safety and Comfort
Place the monitor directly in front of you. To deter-
mine a comfortable viewing distance, stretch your
arm toward the monitor and notice the location of
your knuckles. Place your monitor near that location.
You should be able to see the text on your monitor
clearly.
