For many of us, our primary workplace consists of a computer desk. Although sitting at a desk and typing all day long may not seem like hard work, it can cause pain in the arms, neck and shoulders if the height and position of the desk aren't correctly adjusted. Fortunately, finding the right height for your desk is as simple as setting a height for your chair and performing a few practice tests.

  1. 1

    Set your desk chair to the height that is comfortable for you. You should be able to sit upright in the chair with the upper legs parallel to the floor and your feet flat on the floor.

  2. 2

    Hold your forearms out at a 90-degree angle, with your upper arms loose at your sides. Measure the height of your hands from the floor.

  3. 3

    Adjust your computer desk so that the position of the keyboard will be just under your hands. A 90-degree angle gives the best posture for typing and mouse use.

  4. 4

    Place your monitor on your desk. Ideally, the upper part of the monitor, about 5-8 cm (2-3 in) below the top of the casing, should be at your eye level. If it is too low, raise the monitor by placing an object under it, such as a book or monitor stand. Raising the desk itself will only leave you typing with your arms at an uncomfortable angle.

Tips and warnings

  • You can use an online desk height calculator to give you approximate heights without the need for trial and error. Because people are different, there may be a few centimetres' variation in the perfect height for you. For an example calculator, see the Resources section.
