Work Heights for Sitting and Standing:
Position your input devices at elbow height
- Shoulders relaxed with upper arms hanging normally at the sides of your body.
- Elbows bent at 90 degrees or in a more open angle.
- Forearms in-line with wrists so that wrists are not bent up or down.
Adjust monitors slightly below eye height
- Head remains upright and neutral, while eyes gaze slightly downwards
- Bifocal or progressive lenses may require lower heights.
- Monitor distance (18-30”) should allow comfortable viewing without forward leaning.
Work Surface Too High?
Work Surface Too Low?
IF YOUR DESK IS TOO HIGH OR TOO LOW
- Measure your elbow height to determine which height to change your desk to.

Refer to the Campus Office Ergonomics eCourse and Self-Evaluation for more information.
How to Measure Elbow Height
- Adjust your chair: Chair Adjustment Job Aid
- Sit deep into your chair with your hips at approximately the same height as your knees, with your feet supported on the floor.
- Relax your shoulders and allow your arms to hang comfortably by your sides.
- Bend your elbows approximately 90 degrees or in a more open angle, while keeping your hands in line with your forearms.
- Measure the distance between the floor and your elbow (green line in photo).
- Select the closest desk height option that matches your elbow height. Many desks adjust in one-inch increments.
- Test this height for comfort by using a keyboard tray or other surface set at the test height before placing the work order. If needed, ask your supervisor or a coworker to hold a notebook or other firm surface at the measured height.
How to Change Your Desk Height
To raise/lower your desk, contact your supervisor or UCSF Logistics to help you with this request. If you change your desk height, you may need to raise/lower your monitor in order to keep it slightly below eye height.
