Viewing Angles and Distance

  • Position monitor, keyboard, and chair in straight line,
  • Top of monitor screen at or slightly below the eye horizon,
  • Comfortable, non-straining distance to read monitor (typically 15-30 inches),
  • Adjust brightness, contrast, and color to comfortable levels,
  • Avoid glare by positioning away from windows and direct lights,
  • Keep written work materials propped up near monitor screen.

Neutral Typing Position

  • Use an adjustable chair, keyboard tray, or desk/table to achieve the "neutral position" of a straight hand: wrist: forearm,
  • Keep upper and lower arms at a 90 degree angle to each other,
  • Position mouse as closely to keyboard as possible to minimize reaching and twisting.

Lower Back Support

  • Use a chair that provides lumbar (lower back) support - if adjustable, adjust to maintain an erect sitting posture,
  • Ideal chairs can be easily raised or lowered, and have 5 wheel legs for safety,
  • Keep feet planted firmly on floor or footstool to counterbalance forces on lower back.

Legs and Feet

  • Plant feet firmly on floor or - if not possible - use a foot stool,
  • Keep thighs parallel to floor,
  • Ensure leg clearance from table or keyboard tray to avoid bumps, scratches, pinches, and torn clothing.
