I’m struggling to change the scale of my map using the tmap package. I’ve attempted to adjust various parameters using the ‘scale’ argument in the tmap_save function, but it seems that this doesn’t resolve my issue.

As you can see from comparing the two maps, the one on the right appears smaller than the other one, despite both maps having the same cell size. At the end, it looks like the size of the cells is smaller compared to the other one. This discrepancy is due to the fact that the second city is significantly larger than the other one. Therefore, I’ve been trying to find a way to make the larger city appear bigger on the map. Any suggestions would be greatly appreciated. Thank you!

This is the code I used to create the two maps

tm_shape(shapefile) + 
tm_borders() + 
tm_layout(frame = F) 
tmap_save(shapefile, "shapefile.png",height = 11.27, width = 14.69)
