This is how the blog looks:

When you go to the expanded post, I want it to be a wide page with no sidebar. Setting that for each new post is not the problem. The problem is the old posts of which I have 5000+.
I have gone into each post for August – June 2017 over the last 3 days to change it manually so it looks like this:

I have posts from May 2017 to March 2012 that need to be change from default to the format above. That’s 5000+ posts so if there is a way to set the option in code so all of the old posts appear like above without having to individually go into each post and manually do it would be great.
