Computer Monitor Height

• The top of your monitor should be at eye level.
• However, lower is preferable to higher to allow for natural lowering of vision below the horizon.

Computer Monitor Distance

• The viewing distance is dependent upon the task and the visual display and should not be less than 300mm. For visual displays used in offices, a longer viewing distance (400mm to 750mm) is recommended as this leads to less strain on the eyes and allows greater freedom to move the head.’ ISO 9241-303:2008

Computer Monitor Horizontal Placement

• The ideal horizontal position for the screen is directly in front of the user so that the head, neck and torso are not turned to one side.
• The screen and document are positioned as close as possible to each other; The screen(s) is not placed more than 35° to the left or right of the user.

Computer Monitor Tilt

• The height and tilt of the screen should be easily adjustable to maintain an appropriate viewing angle. The bottom of the screen should be slightly closer to the user’s eye than the top as our eyes are accustomed to higher objects being further away.
• Note that tilting the screen forward to avoid glare problems on the screen is not an acceptable solution to lighting problems. It is recommended that LCD screens have a minimum tilt adjustability of 0° to 20°;

Computer Monitor Swivel

• The screen should swivel from side to side at least 45° in each direction.
