I'm using QGIS v.3.22.0. I've been going crazy trying to adjust a map size to match a graticule in the Print Layout. I don't want to have any squares cut in the middle. I don't want to adjust the grid to match the map size obviously, because that would change the interval I want to use in the grid.
All I want is to be able to adjust the map's dimensions in such a way that it matches the grid. The problem is when I try to do this manually, it automatically zooms, changes the scale, and changes the grid.
