Thank you, I am experimenting with changing the map canvas now. You’re correct as well, I am looking into getting an updated version of QGis also. With an updated version of QGis what is the normal function one would otherwise use to do this?

Hi Mike,
 
  
 
Firstly I would say that you should seriously think about updating your QGIS, as 2.18.28 is very old. The current long term release version is 3.28.5. QGIS 3 has many improvements over 2, and has been in development for long enough that the bugs are mostly worked out. I can not remember your specific issue from 2, but I know that labeling has been much improved recently in 3, with very good, but not necessarily perfect, correspondence between how labels look in the layout and how they look on exported pdf's and images, the difference is mostly just that occasionally a label will not shows up on an export when it is present in the layout. I have not noticed differences in size or font. The correspondence between labels in the map canvas and the layout/print is much improved also.
 
  
 
You may want to try adjusting your map canvas scale to match the scale in the layout. I have found that there is usually a sweet spot where the map canvas labels display almost exactly the same as in the layout.

    labels the same size when exporting Map as pdf or image via composer

Good morning,
 
  
 
I?m messaging as, when I export my Map as pdf (or as image) the labels on the Map are smaller than what is shown when I preview after ?drawing the map? in the composer manager.
 
  
 
At present I can remedy this to an extent by lowering the MAP dpi in composer manager, but this obviously comes at the cost of the labels teetering on illegibility (which is just another version of the issue I?m trying to remedy in the first place). I understand a better remedy might be a case of converting the raster layer (which I am only presuming is the underlying map that I?m having issues with) ?from pixels to points? (or vice versa).
 
  
 
However, I have QGis version 2.18.28 and there doesn?t appear to be any explicit function pertaining to this, and indeed said remedy may in fact be something different entirely. Am open to any alternative resolutions if so, hope you can help?
 
  
 
Note: Have attached a version of the Map which I?ve managed to sort based on lowering the dpi, which as you can see works ok but it would be preferred to have it clearer.
