Oh! Didn't know you meant in general. That's the way its always been. Geo has been roughly four footish while Ronts has been roughly three footish. I don't really know /why/ Geo has been taller. It just made he most sense at the time and I can't remember the reasons why.
Ronts just happens to be shorter. Except for the times that Geo is average raccoon proportion, which doesn't happen often...but happens Enough.
