An individual workstation should provide the operator with a comfortable sitting position sufficiently flexible to reach, use and observe the screen, keyboard and any paper document referred to while keying. Some general guidelines to minimize fatigue include:

Posture Support

The seat and backrest of the chair should support a comfortable posture permitting occasional variations in the sitting position. Chair height and backrest angle should be easily adjustable. A footrest may be necessary.


When using the keyboard, the upper arm and forearm should form a right angle. The hands should be in a reasonably straight line with the forearm, using a wrist rest. Long or unnaturally high reaches should be avoided. Armrests should also be avoided while keying.

Legs and Feet

The chair height is correct when the entire sole of the foot can rest on the floor or on a footrest and the knee is level with or slightly higher than the hip. This allows blood to circulate freely in the legs and feet.

Monitor Position

Monitors that adjust vertically enable the operator to select the optimum viewing position.  Eyes should be level or slightly below the top of the screen. The monitor should be centered and approximately one arm's length away (or closer for better vision). 

Workstation Surface

The table or workstation should suit the task to be done. It should be large enough for reference materials, files, telephone, calculator or other necessary items and also permit different positions of the screen and keyboard. An adjustable surface height is an advantage.
