Ideal Monitor Viewing Distance Calculator
Recommended sitting distance from monitor size and resolution — far enough for comfort, near enough to use the pixels.
Two limits bracket the answer: too close and a big screen forces head-turning and eye strain; too far and you can't resolve the detail you paid for. The classic guidance is roughly arm's length (50–70 cm) for a 24–27″ monitor. Higher resolution lets you sit *closer* before pixels show — one reason 4K shines on large or close screens but is wasted at a distance.
