1. Knee space should measure at least 20” from side to side under the work surface;
24” of knee space is preferred.
2. The underside of the work surface or keyboard tray should be higher than your
knees. If you work at a desk with a work surface that cannot be raised or lowered,
the clearance under the work surface should be at least 26.2”.
There should be at least 12.2” of front-to-back clearance at knee height, measured from
underneath the front edge of the work surface back toward the wall supporting the work
surface. Taller people will need more clearance. Now adjust your Kinesis keyboard and
computer monitor.
Adjusting your Keyboard
Adjust the angle and height of your keyboard so that the front of the keyboard is
approximately at the same height as your elbows. Your forearms should be parallel to
the floor. Be Careful of the Following:
1. Are you striking the keys on your keyboard too hard? Try to remember to soften
your touch.
2. Are your shoulders raised or hunched? Relax and lower them. If the armrests of
your chair are forcing your shoulders up, consider asking to have the armrests
removed. If your work surface is forcing your shoulders up, consider asking to
have it lowered.
3. Do you keep your hands poised above the keyboard? Relax them; don’t allow
yourself to keep your hands frozen in one position. Remember mini-breaks.
4. Are you leaning against a sharply angled edge? Move back to relieve pressure on
your forearms.
5. Are you leaning over to reach things in your workstation that could be placed
closer? Do you often reach behind your body or above shoulder height to retrieve
something that could be moved forward or down? Try to find an arrangement that
keeps materials you frequently use within convenient reach (about 20” away for a
heavy object).
Finally, listen to your body. If you think you may be more comfortable adopting a
different posture or way of working, experiment! And if you are experiencing persistent
discomfort or unusual sensations, see a health care professional for advice.
