*bangs head against a table* Brain's...dead...need....something that's...funny....*looks at Tumblr posts send via text* Oh! This one's funny!

Lol, I personally headcannon that Kai is taller than Jay. Actually, I'm gonna put down what I headcannon to be the ninja's heights.

Zane I believe would be the tallest, and he's around 6'1-6'2.

Kai's the next tallest at 5'11(though he says he's 6'0 because he's Kai. XD)

Cole...mmm, I either headcannon that he's slightly shorter than Kai(around 5'10) or that he's the second-shortest of the ninja(at around 5'8).

Lloyd(as a teen) is around 5'9

Poor Jay is the shortest ninja at about 5'7-5'7.5. XD 

What about you guys? How tall do you believe the ninja are? Who's the tallest? Who's the shortest? Tell me what ya think! :)
