SSA/ASS subtitles are scaled proportional to movie height, so with these two 
movies their size (in pixels) should be identical. If you have a sample where 
they aren't, send it.

Different fonts can have different visual sizes with the same FontSize. You 
can check if this is the case by changing FontSize directly in the subtitles 
file, not relying on ass-force-style. This is especially true with FreeType < 
2.2.0.
