forgottenhsfacts:

Cause I just spent a bunch of time figuring it out. Follow my logic.

So the Dream Towers on Prospit are the same size as Jade’s house. We know this because of her dreambot

Jade’s house is about half the size of the Volcano

Measure that out and that leaves Propsit at being 5 volcanoes across

Prospit is tiny in comparison to Skaia

Count that out and Skaia is 37 Volcanoes in diameter

Skaia is the same size as the Player Planets therefore each planet is 37 Volcanoes in Diameter

But wait?? How many measurements is a Volcano??? Well to that we look here.

Based on some yacht websites, yachts like that are about 200 feet long so turn that sideways against the volcano and it’s about 240 feet tall

120 times 37 equals 8880 feet or 2707 meters. 

Meaning each planet’s diameter is about 1.68 miles/ 2.7 kilometer

Okay so everyone’s mentioning perspective so here’s a way that doesn’t use that, where everything is next to each other 

So 1.5 miles/2.4 km, about the same. Def in that ballpart
