1/2" difference.....
A bit of trivia.....the other day one of my bathrooms needed a sully of tp......so I got a few rolls from stash. These were the "new" mega rolls.. On the dispenser was the remnants of a "regular" roll. When I was replacing, I looked at the actual tissue, and thought, hmm....one looks a bit narrower than the other...so I did a comparison. Sure enough! The regular roll's paper width is almost 1/2" wider than the new "mega" roll. Don't remember which brands I was comparing, if that makes a difference, don't know, but it was an interesting moment.........so here again we have a bit less of product.
