Is there any difference for the old Pampers Baby Dry Size6(16kg+) or the new Pampers Baby Dry Size7(15kg+)

I wore Old pampers Baby Dry size 6 4 years ago. At that time I had a 75 cm waist. I need to stretch the tapes a lot to fit into those.
Now the package changed. And size 7 appeared.
I want to ask, is there any sizing differnece in these two diapers? The new ones are longer? More strectchier waist? Wider?

enerally size 6 and 7 are the same length but size 7 is strecher. I'm not sure if they changed things up though over in the UK since they added a size 8. I imagine size 7 UK are same as americas size 7.I bought some like last year when they introduced the new no sag features and they measured the same.
