Chapter 2. Arranging Your Workspace
To get the most from your computer, arrange both the
equipment you use and your work area to suit your
needs and the kind of work you do. Your comfort is of
foremost importance, but light sources, air circulation,
and the location of electrical outlets also can affect the
way you arrange your workspace.
Comfort
Although no single working position is ideal for
everyone, here are a few guidelines to help you find a
position that suits you best.
Sitting in the same position for a long time causes fatigue.
A good chair can make a big difference. The backrest
and seat should adjust independently and provide good
support. The seat should have a curved front to relieve
pressure on the thighs. Adjust the seat so that your
thighs are parallel to the floor and your feet are either flat
on the floor or on a footrest.
When using the keyboard, keep your forearms parallel to
the floor and your wrists in a neutral, comfortable
position. Try to keep a light touch on the keyboard and
your hands and fingers relaxed. You can change the
angle of the keyboard for maximum comfort by adjusting
the position of the keyboard feet.

Height
Adjust the monitor so the top of the screen is at, or
slightly below, eye level. Place the monitor at a
comfortable viewing distance, usually 51 to 61 cm (20 to
24 in.), and position it so you can view it without having
to twist your body. Also position other equipment you
use regularly, such as the telephone or a mouse, within
easy reach.
Glare and Lighting
Position the monitor to minimize glare and reflections
from overhead lights, windows, and other light sources.
Even reflected light from shiny surfaces can cause
annoying reflections on your monitor screen. Place the
monitor at right angles to windows and other light
sources, when possible. Reduce overhead lighting, if
necessary, by turning off lights or using lower wattage
bulbs. If you install the monitor near a window, use
curtains or blinds to block the sunlight. You might have
