Original Description:
 
I used bases to make things easier and more show accurate but I used Inkscape to make them look cleaner
 
original base owners are down below:

the rest are mine.
 
I want to make a Hight chart for certain characters and races
 
The wolf ponies: the wolf ponies in their wolf form are slightly bigger than normal ponies but depending on the pony if the pony is born huge (like big mac or trouble shoes) then their wolf forms are HUGE as big as a cow but taller almost as tall as Celestia.
 
Adam: Adam is said to be 8 feet tall (i think) so is the same in Equestria and he is slightly bigger then Celestia since idk if Celestia is supposed to be 7 feet tall also if Adam were human, he will NOT doe young because of his Hight because I think he is literally built to be this tall so he’ll be fine.
 
the swamp ponies I’ve updated to be almost as tall as Celestia for the males and females are shorter.
 
I’m going to do drawings for an updated “wiki” like thing so I can keep track of stuff and also just because I want to I think is really cool to have a “wiki” for this world.
 
it’s kind of hard getting things accurate when there is barely any size line up like in that cheese sandwich episode.
 
characters like Hyde and the others are like the average pony though some are slightly shorter or taller than others
