World Descriptions
This makes the far south eastern continent as wide as the part of Africa stretching from the upper tip of Somalia to Freetown, Sierra Leone, or roughly 4500 miles. It is of Equal height, so it would stretch roughly the entire north-south length of Africa as well. More or less, this continent is an Africa that is perfectly squre, thus the ocean would be filled with land to make it a box of sorts.
This would make the southern part of the main continent roughly 7000 miles wide, or roughly the distance from Gibraltar, Spain to Tokyo Japan. Additionally from the mountain range at the very southern tip of the main continent to the top of the mountain range past the Avia territory, it is roughly 6500 miles.
The northern part of the continent stretches even further, probably in the neighborhood of 8500 miles wide, or in plain terms, the above journey from Tokyo to Gibraltar, then traveling to London.
This makes the great sea in between the main and east continents roughly 4500 miles wide.
The Marin Lake (possibly consider breaking them up into several large lakes, but maybe keep them) are roughly 565 miles across, thus making them the width of the northwestern great lakes, Superior, Michigan and Huron.
The Island of master humans should be about 4000 miles wide and 1500 miles high. 1500 miles is roughly the distance from the southernmost tip of Texas to the flat northern border of the United States in the Dakotas.
The distance of the great ocean from the edge of the Marin land to the southern part of the northeasternmost continent (the new world so to speak)is roughly 5200 miles. By comparison the Atlantic Ocean is 4000 miles from the tip of Florida to the western edge of Africa (Western Sahara).
That would make the total distance from edge to edge of this world roughly 24,000 miles across. Thus the circumference of this planet is nearly identical to that of earth.
