The scale is usually referenced to the center of the map (I don’t have any around anymore, but I think the USGS Topos say so on them). However, the issue of the scale depends on the projection you are using and, I am pretty sure, the geoid you are using.

Hello,
Greetings!
When we make a map, we add a graphical scale bar as a measurement/indicator of linear distances. We also know the distance is not the same as it goes from south to the north. My question is where the scale bar is precisely referenced to? The center of the map or somewhere?
Thanks,
Yurong
