My Glorantha varies. It is much smaller. Furthest to Boldhome is 4.5km, Boldhome to Nochet 2.8km. Paraguas Walls are 34cm high, Gonn Orta about 6ft tall, and the Block only 27metres on each side.
Humans are about an inch tall, while some insects are normal size (to us) but appear to be gigantic to Gloranthans.
My Glorantha is 1:72 scale.
