Hello, @fbtwtf . . . just using my ruler, I come up with the following.
AIBI is about 2-1/2 inches tall and about 1-1/2 inches wide and front to back about 1-1/2 inches (mostly due to his head).
In his bunny costume he is about 3-1/2 inches feet to top of ears.
The necklace extends out to 13 inches. The pocket magnet is 1-1/2 inches wide and 1-2/3 inches tall.
I hope this helps. If you need metric, @edward should be able to answer that.
