Based on this question, ["Why do many sites leave half of each webpage empty?"](https://ux.stackexchange.com/questions/104705/why-do-many-sites-leave-half-of-each-webpage-empty/104743#104743) 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 on 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?
