At a distance of 1 meter, what is the maximum DPI resolution that the eye can discern?
I suspect about 100 dpi
above which value there is no point in excess resolution?

maybe there is a table or formula for resolution / distance

and I'm talking about the normal vision of an ordinary average person

Answer 1

Depends on the eyes. There are people with vision 2.0 +

Answer 2

It is necessary to complain about Google to the ECHR for banning people left and right. :)

Normally, the human eye is able to separately perceive objects, the angular distance between which is not less than 1 ′ (1 minute).

Further elementary school trigonometry.

Answer 3

from this article - https://habr.com/ru/post/450072/?_ga=2.142371570.1...

at a distance greater than 2873.6 pixel sizes, the eye will not see the graininess.

300dpi - 24cm
200dpi - 36cm
150dpi - 48cm
100dpi - 73cm
