The A321 is not wider than an A320. The A320 family[1] comes in a variety of sizes and configurations to support different profiles, but they are all variations in length, fuel capacity and MTOW.

Making a plane longer is relatively straightforward, just insert additional sections before or after the wings. Making a plane wider you may as well design a whole new aeroplane.

I said "cabin is a bit wider" not the plane itself. I was under the impression that with neo they made the isolation on the walls of the cabin a bit thinner (2 inches?) gaining more room in the cabin while keeping the outside shape the same but I can't find anything about it anymore
