When making detailed maps having clearly defined borders matters a lot. I often find when zooming out on the maps that the set proportions seem to get messed up, extending out in one or both directions, making some of the maps take on a really sloppy look. I have 0 idea if my players see this issue too, which concerns me since I work very hard to set a certain atmosphere and buggy borders on maps really break the immersion for me when GMing.
