Monitor Viewing Distance Calculator
A practical desk-distance range from monitor size, aspect ratio, and use case. Not a medical standard.
Result
Practical range: 50–84 cm
Based on 1.5–2.5× screen height for mixed desktop use on a 16:9 panel. This is a desk-distance rule of thumb, not a medically correct universal distance.
How this was calculated
- Screen height is derived from the diagonal and aspect ratio.
- Distance range is a multiple of screen height: general 1.5–2.5×, productivity 1.2–2.0×, gaming 1.0–1.8×.
- This is a documented desk rule of thumb, not the TV 30°/40° FOV method.
Limitations
- There is no single medically correct universal distance.
- Chair height, glasses, and desk depth can reasonably move you inside or outside the range.
