Thanks, Redrobes!

Midgardsormr is quite correct. I created the map at the intended print scale of 24" x 36". The posted file is a 100 ppi, JPG reduced to 70% quality to achieve its current file size. Just to make a smaller file to upload/download.

Because I created this map in Xara, I still have the .xar file, which because is a vector file is resolution independant until I export it. When I do print, I will export the file as a 300 ppi TIF or just print in native scale and format directly from Xara to my new Canon printer.

I create the scale and dimensions based on intended end result, yet with the freedom to go larger or smaller as need arises.

Of course, see the thread "Regional Maps in Xara Xtreme 4.0" in the Tutorials Forum to get an idea, how I created this map.
