The numbers, in one place
| Measure | Figure |
|---|---|
| Ergonomic assessment | many employers offer one; ask HR or your safety team |
| Monitor position | top of the screen at or slightly below eye level |
| Viewing distance | about an arm's length, roughly 20 to 40 inches (50 to 100 cm) |
| Break interval | change position every 30 minutes or so |
| Eye breaks | every 20 minutes, look at something 20 feet away for 20 seconds |
In one paragraph
A poorly arranged workstation is linked to neck, back, wrist and eye strain, and the largest single factor remains how long you stay in one position.
Worth doing
- Ask your employer for an ergonomic assessment of your workstation
- Set the chair first, then the desk height, then the screen
- Get an eye exam if you have frequent eye strain or headaches at the screen
- Change position regularly rather than chasing one perfect posture
Worth avoiding
- Working from a laptop on your lap for long periods
- Holding a phone between ear and shoulder
- Assuming equipment alone removes the need to move

When to speak to a doctor
See your doctor for persistent numbness, tingling or weakness in the hands or arms, which can indicate nerve compression. Go to the emergency room or call 911 for sudden weakness in both legs, or any bladder or bowel changes with back pain. Report work-related symptoms to your employer.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarized or generalized beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
