Is 80 gms printer paper getting thinner - or am I just imagining it!
Certainly getting more expensive


I suspect if it is getting thinner - then it will be getting wider or
longer if it is to maintain the 80gm spec.

You fail to allow for the possibility that it is getting denser.
Slightly less unlikely than the size of A4 changing significantly.


and in any case it's 80 grams *per square metre*, so changing the size of A4 would have no effect.
