He's not 5'4 as claimed. He's more like 5'1
My friend who is 5'4 and doesn't lie about his height met him and he can say 100% that this guy isn't 5'4. He really is tiny.
He was surprised because he's met other "short" celebrities and they're around his height but not Kevin Hart, he actually is child size.

Jack Black is supposedly 5'6 (hes probably 5'4) but regardless, look how much shorter Kevin is!
