I am trying to put a map into the center of my ArcMap's layout view. I have checked various options (Full Extent; Zoom in and out; File --> Page Print Setup) but neither of them solved the problem.
Currently, my map looks like this:
And a while ago I managed to produce this map. I remember that it involved selecting a pre-defined "A4" sized page in one of the menus. Unfortunately, I am unable to reproduce how I got there.
Now I would like to center the first map in the same way as the second map. I am aware of at least a subset of similar questions that were asked on this site. All solutions that I found there, however, involved manually shifting the map around. Ideally, I would like to reproduce exactly what I did such that the map extent of both maps is the same.
