Based on this question, "Why do many sites leave half of each webpage empty?" and its comments and answers, I did some research, but I didn't find a complete answer.
For me it is obvious that it is a good decision to limit the width of the main container, but what is the recommended max-width for the main container for large screens, in 2017, when the screens become larger and larger? What variables should be considered in this decision?
Also, let's say a website has multiple columns in the main container, what is the max-width for the main column?
Update: I have now a related question. I recommended to one client to reduce the width of the main container in the homepage, but I can't convince him. It is a website with photos, like pexels.com. It is in this case important to limit the width if the elements are not one more important than other?
