We use Charmin, not the linty one, I noticed when they "improved" it. It was an inch or more shorter and yes roll is bigger. I have noticed Oreo original cookies are thinner and smaller in original package it is very easy because the package is baggy. I have noticed some others that are smaller, same package probably all of them cost more.
My big gripe is leave them all the same size and just raise the price. They (companies) think we are too stupid to notice, very insulting. I am buying more generic products, same size and taste good.
