How to Set Up Your Keyboard


Keyboard Positioning

  • The keyboard should be positioned directly in front of the user at a height and distance that promotes the best posture. 
  • The keyboard should lie flat or negatively inclined (i.e., tilted slightly away from the user) and not be propped up on the keyboard legs to promote neutral wrists.

Body Positioning

  • The ideal position during keyboard use includes the following:
    • Shoulders are relaxed and close to the sides of the body
    • Elbows are bent to 90 degrees
    • Hands are aligned with the forearms
    • Wrists are relaxed and in a neutral position
    • Fingers maintain a comfortable, natural curve
    • Thumbs rest on the space bar

What Not To Do


  • Potential Hazards
    • Keyboards that are positioned too high or too low can put undue stress on the wrists, arms, and shoulders.
      • Examples:
        • Keyboards that are too low may cause the user to type with their wrists bent up.
        • Keyboards that are too high may cause the user to raise their shoulders in order to elevate their arms to the level of the keyboard.
    • Keyboards that are positioned too close or too far away may lead to poor postures.

  • Keyboards that are too far away may cause excessive trunk leaning and/or an elbow angle that is too open.
  • Keyboards that are too close may cause extreme bending at the elbows.
  • Standard articulating keyboards can cause the wrists to bend sideways in order to reach all the keys.
