Computer Workstation Ergonomics: Monitor, Chair and Movement Basics

This article has been rebuilt for an international audience using current official or authoritative sources. It explains the original topic without carrying forward unsupported numbers, guarantees or culture-specific assumptions.
- There is no single “golden angle” that fits every body and workstation.
- The screen should generally be directly ahead, with its top at or below eye level.
- Frequent position changes and breaks matter as much as static posture.
Start with adjustability
Ergonomics aims to reduce awkward posture, force and repetition. A good setup lets the user keep the head balanced, shoulders relaxed, elbows near the body and wrists reasonably neutral. Body size, vision needs, task and equipment all affect the correct adjustment.
Monitor placement
OSHA recommends placing the monitor directly in front of the user, at least about 20 inches away, with the top line of the screen at or below eye level. People who use bifocals may need a lower position. Reduce glare by placing the screen perpendicular to bright windows where possible.
Chair and input devices
Adjust seat height so the feet are supported by the floor or a footrest. The backrest should support the lower back, and the seat should not press behind the knees. Keep the keyboard and mouse close enough that the elbows remain near the torso. Laptop users working for long periods may benefit from an external keyboard and raised display.
Movement is part of the setup
Even a well-adjusted chair does not make prolonged sitting harmless. Change posture, stand, walk and look away from the screen regularly. Persistent pain, weakness, numbness or visual symptoms should be assessed by an appropriate health professional.
Rules, product specifications and local conditions can change. Use the linked primary sources and current local guidance before making legal, tax, health, travel or purchasing decisions.
