Choosing an Ergonomic Location for Your
Computer
Before you get started, find the best location for your new computer. Here are
some things to consider when planning your workspace:
❑ Stable work surface — Use a stable work surface large enough to support
the computer and other peripheral equipment.
❑ Ventilation — Leave at least eight inches of space on the left and back sides
of your computer to enable proper ventilation.
❑ Placement of the keyboard, mouse, and other input devices — Place
your keyboard, mouse, and other input devices so that your arms and hands
are in a relaxed, comfortable position. The keyboard should be directly in
front of you. Adjust the level of the keyboard so that your lower arms are
parallel to the floor. Keep your wrists in a relaxed position when you are
using the keyboard—not angled up or down. Use the palmrest only briefly,
for resting. While typing, never use the palmrest or rest your hands on the
table. Position the mouse at the same level as the keyboard. Hold the mouse
with a relaxed hand, and use your whole arm to move it. Take breaks during
sessions with your computer. Excessive use of the mouse or a joystick may
strain muscles or tendons.
❑ Furniture and posture — Sit in a chair with good back support and
armrests. Adjust the level of the chair so your feet are flat on the floor. A
footrest may make you more comfortable. Sit with relaxed, upright
posture—avoid slouching forward or leaning far backward.
❑ Viewing angle of the display — Position the display 18 to 26 inches
directly in front of you, with the top of the screen at or a little below eye
level. Use the display’s tilting feature to find the best position. You can
reduce eye strain and muscle fatigue by placing the display in the proper
position.
❑ Lighting — Choose a location where windows and lights do not create glare
and reflection on the display. Use indirect lighting to avoid bright spots on
the display. You can also purchase accessories for your display that help
reduce glare. Proper lighting adds to your comfort and work effectiveness.
