That’s absolutely not the case. Look at the pictures in the thread I
linked. Here is the mini, the (old 6.7”) Pro Max, and the Fold on top of each other:

The Fold screen is only around 35% wider than the mini screen.
The numbers I cited were for the screen alone, without bezels, since for the Apple Fold we only have accurate numbers for the screen. The Pixel Fold screen is 2.65” wide. As I said, I would assume that the bezels on the Apple Fold will be thinner than those on the Pixel Fold, because the latter were really wide.
