Getting Started
Selecting a place to work
❖
If you are using an external monitor, the top of the display
should be no higher than eye level.
❖
If you use a paper holder, set it at about the same height and
distance as the screen.
Seating and posture
When using your computer, maintain good posture with your
body relaxed and your weight distributed evenly. Proper seating is
a primary factor in reducing work strain. Some people find a
backless chair more comfortable than a conventional chair.
Correct posture and positioning of the computer
Whichever type you choose, use the following guidelines to adjust
your chair for maximum computing comfort.
❖
Position your chair so that the keyboard is at or slightly below
the level of your elbow. You should be able to type
comfortably with your shoulders relaxed and your forearms
parallel to the floor.
If you are using a conventional chair:
❖
Your knees should be slightly higher than your hips. If
necessary, use a footrest to raise the level of your knees and
ease the pressure on the back of your thighs.
