Padding size

Could anyone who has a Medium Rearz Safari, Princess, or Black Diapurr measure the padding length and inform me? Also for the Bambino diapurrs, I wish the Abu Space padding was longer, like the M4, but it's just a few inches shy and it really bothers me :/ I love them so much, but I really need the extra length if that makes sense. I want to get a new AB Diapurr that's long like the m4, but is cuter, even though the cost may be much greater
