Add default paper size inline with Language Settings in Yast.

Add in selection of language a “default paper size”

For example I selected English UK. In options I select a default paper size of A4 amongst all other paper definitions.

ALL applications would then adopt the default paper size. Every application that is capable of selecting a paper size will inherit the default.

Example everything in open office, Evolution and Kmail and Image applications will use the default.

I associate the default paper size with language as normally by selecting a country you normally associate a country and its language with a paper size default.
