Teutonia is a large place. To compare it to our world It would begin at France's west coast and reach all the way to eastern Ukraine. From the Baltic Sea all the way down to mediterranean and the Southern tip of mainland Italy. Teutonias west coast is shorter than its eastern boarders, Archangel (or Karelia) would sit in Latvia whilst Vilnus would sit in Patras, Greece.
Thats how big of an area Teutonia covers, it's the size of most of Mainland Europe.
