Exactly how big is lenny?

In all three of the Toy Story films there are small diffrences between the size of a single character from scene to scene, particularly in background characters. Perhaps worst effected was my personal favourite Lenny. I have done extensive research by studying his size in various scenes, compared especially to woody and buzz of whom their dimensions are known. I concluded that Lenny what usually around 3 1/2 inches wide, and 2 inched tall when standing erect. Lenny is a very longg (or thick if you will) character, which distorts the appearence if his size, and he often stands facing slighltyu upwards, his body pivited on his legs. What do you guys think?
