What is the real height of randy orton and how long are his arms?

RKO in my opinion is the best superstar in the wwe and he will win the money in the bank and get back the wwe title because it looks gay on sheamus. wwe website says hes 6'4 and some other sources say he is 6'5 and one said he is 6'6. just exactly how tall is randy orton and how long are his arms
