Well Tori is 2.85 units tall, so if you think Toribash uses the metric unit then it's 2.85m tall. Which is quite tall.
Typing /am 1 will give you 2.59 units of height when you pause the game on the first frame (meaning of you have 500 frames to start out, you will pause at 500).
So the height of tori is 2.59 units tall. (Assume the unit of measurement is in meters)
