Keyboarding Ergonomics
Teaching students about proper posture and physical setup can help them
prevent health problems caused by typing.
Keep the following tips for wrists and hands in mind:
• Keep wrists aligned, straight, and level. (See the illustrations below.)
• Position chairs so students do not stretch to reach keys.
• Wrists should not rest on anything.
• Take periodic rest breaks.
Follow these guidelines to properly adjust equipment and posture:
• The keyboard should be just below elbow height so the elbows are bent at a
90° angle.
• The chair should adjust so it can fit the various sizes of your students.
• Forearms and thighs should be parallel to the floor when the student is
seated at the computer.
• Feet should be flat on the floor or placed on a tilted footrest.
• Position devices so that light does not reflect off the screen. Light reflecting
off the screen can cause eye strain and frustration.
