There are some guidelines for selecting screen size based on distance to viewer. There are even certifications to be satisfied in, for example, movie theaters.
The attached article contains a chart, any you find will show the same.
Optimal screen size for typical desktop installation is 24-27" screen. Bigger than that would require more distance between viewer and screen. And as the chart represents, the bigger the screen, the greater the distance should be. This is determined by the viewing angle of the eye at 20/20.
These are only guidelines for typical installations. CAD/CAM, for example, would need greater resolution but bigger is not necessarily better.
Again, these are guidelines, not "standards"...
